Cervicitis
Introduction
Background
Cervicitis is an inflammatory condition affecting the cervix uteri, the lower, narrow part of the uterus that connects to the vagina. It is clinically defined by ICD-10 code N72, ICD-9 code 616, and ICD-8 code 620. [1] While often asymptomatic, cervicitis can manifest with symptoms such as vaginal discharge, bleeding, or pelvic pain. This condition is a common gynecological finding, particularly among women of reproductive age.
Biological Basis
The inflammation characteristic of cervicitis can arise from various factors. Infectious agents, particularly sexually transmitted infections (STIs) like Chlamydia trachomatis and Neisseria gonorrhoeae, are frequent causes. Other potential triggers include bacterial vaginosis, allergic reactions, or physical irritation. Research indicates that host genetics play a role in the susceptibility and progression of cervical phenotypes, including cervicitis. [1] Genome-wide association studies (GWAS) have identified specific genetic variants associated with cervicitis, such as rs1049137, rs12611652, rs6866294, and rs36214159. [1] These genetic associations contribute to a more comprehensive understanding of cervical biology and pathology, complementing the understanding of environmental and infectious etiologies. [1] The human papillomavirus (HPV), a primary initiator of cervical cancer, also interacts with host genetic factors, particularly in the HLA region, influencing immune response and disease pathogenesis. [1]
Clinical Relevance
Cervicitis is clinically relevant due to its potential impact on women's reproductive health. If left untreated, it can ascend to the upper reproductive tract, leading to pelvic inflammatory disease (PID), which can result in chronic pelvic pain, infertility, and ectopic pregnancy. Furthermore, cervicitis can influence the risk and progression of other cervical pathologies. Studies have shown genetic overlaps between cervicitis, cervical dysplasia, and cervical cancer. [1] Understanding the genetic factors associated with cervicitis is an important step towards a more complete understanding of cervical biology and can inform risk stratification for cervical cancer, potentially aiding in screening programs and targeted interventions. [1]
Social Importance
Cervicitis holds significant social importance as a prevalent condition affecting women globally. Its association with STIs underscores broader public health concerns regarding sexual health education, screening, and access to healthcare. The asymptomatic nature of many cases means that cervicitis often goes undiagnosed and untreated, contributing to the spread of STIs and increasing the risk of long-term reproductive health complications. By clarifying the genetic background of cervical conditions like cervicitis, research contributes to better prevention strategies and treatments, ultimately improving women's health outcomes and reducing the burden of cervical diseases. [1]
Phenotypic and Clinical Data Resolution
The research faced limitations in the granularity and standardization of phenotypic data, primarily relying on International Classification of Diseases (ICD) codes for defining conditions like cervicitis. [1] While simplifying analysis, this approach may introduce heterogeneity due to potential variations in code usage across different healthcare systems. [1] Furthermore, the use of publicly available datasets precluded the harmonization of phenotype definitions, which could subtly influence the observed results. [1] A significant constraint was the limited accessibility to detailed clinical information, such as specific human papillomavirus (HPV) status or histopathological features, especially when analyzing summary-level data. [1] This lack of detailed clinical context restricts the ability to fully elucidate the precise role of detected genetic loci in the etiopathogenesis of cervical pathology, particularly concerning specific HPV strains. [1]
Additionally, colocalization analyses were hampered by the absence of actual cervical tissue samples in the available gene expression datasets. [1] Consequently, the study had to prioritize signals from proxy tissues, such as vagina, uterus, oesophagus mucosa, and gastro-oesophageal tissues, chosen for their histological similarity to the cervix. [1] While these approximations are reasonable, they may not entirely capture the unique regulatory landscape and tissue-specific genetic effects within the cervix, potentially leading to an incomplete understanding of gene function in this specific context. [1]
Ancestral Representation and Generalizability
Despite being a pioneering multi-ancestry GWAS meta-analysis for cervical phenotypes, a notable limitation lies in the disproportionately small number of non-European samples included in the analysis. [1] Although similar effect estimates were observed across the analyzed ancestries, the limited representation of non-European populations, particularly Black and Asian individuals, reduces the overall generalizability of the findings. [1] Given the significantly high prevalence of cervical malignancy in many non-European populations, this imbalance restricts the direct transferability and predictive accuracy of the developed genetic risk scores (GRS) to these diverse groups. [1] Future research endeavors should prioritize the inclusion of larger and more representative non-European cohorts to enhance the clinical utility and equity of genetic risk stratification across global populations. [1]
Genetic Heritability and Unaccounted Variation
The study's heritability estimates, while aligning with previous array-based findings, did not fully account for the genetic contribution from the Human Leukocyte Antigen (HLA) region. [1] This exclusion is a significant limitation, as the HLA region plays a critical role in host immune response to infections like HPV, which is central to cervical cancer development. [1] This methodological constraint suggests that the reported heritability estimates likely underestimate the total genetic influence, leaving a considerable portion of genetic variation unexplained compared to higher estimates from family and registry studies. [1]
Furthermore, challenges in constructing and applying genetic risk scores (GRS) were identified, particularly concerning the HLA region. [1] The use of inappropriate linkage disequilibrium (LD) coverage or a failure to accurately capture population-specific LD structures within this complex region can lead to the underperformance of GRS. [1] This highlights an ongoing knowledge gap in fully integrating the multifaceted genetic and environmental factors, such as specific HPV strains and host immune responses, into comprehensive models for predicting cervical disease risk. [1]
Variants
The PAX8 gene encodes a transcription factor crucial for organogenesis, particularly the development of the female genital system, including the cervix. Beyond its developmental role, PAX8 signaling is also implicated in cellular proliferation, with evidence suggesting it can enhance the growth of tumor cells, making it a significant focus in reproductive tract cancers. [2] Located adjacent to PAX8 is PAX8-AS1, a long non-coding RNA (lncRNA) identified as a potential regulator of PAX8 gene expression. [1] Both PAX8 and PAX8-AS1 are prioritized as key candidate genes for various cervical pathologies, including cervicitis, cervical dysplasia, and cervical cancer, indicating their central role in the genetic underpinnings of these conditions.
A prominent genetic variant in this critical region is rs1049137, a single nucleotide polymorphism (SNP) on chromosome 2. This variant has been strongly associated with both cervicitis and cervical dysplasia. [1] Specifically, the G allele of rs1049137 exhibits an odds ratio of 0.92 for cervicitis and 0.92 for dysplasia, suggesting it may confer a protective effect or be linked to a reduced risk of these conditions. [1] While the genetic signal of rs1049137 for cervicitis and dysplasia appears largely independent of signals for cervical ectropion in the same genomic area, it shows a moderate correlation with the lead genetic signals for cervical cancer. This suggests a partially shared genetic susceptibility across the spectrum of cervical conditions from inflammation to malignancy. [1]
The genetic region encompassing PAX8 and PAX8-AS1 is characterized by a credible set of variants, including rs1049137, that collectively influence cervical phenotypes. Many variants within this credible set overlap with regulatory enhancer elements or transcription start site (TSS) flanking regions in relevant cell types, such as HeLa cells. [1] This suggests that genetic variations in this locus likely impact the expression and activity of PAX8 and its antisense regulator PAX8-AS1, thereby affecting cellular processes in the cervix. PAX8 is known to be crucial for the normal development of the female reproductive tract, and its dysregulation can contribute to abnormal cell growth. [2] The interplay between these genes and their associated variants highlights a complex genetic predisposition that underlies not only cervicitis but also the progression towards more severe cervical pathologies like dysplasia and cancer.

Definition and Core Terminology
Cervicitis is precisely defined as an inflammatory disease affecting the cervix uteri. [1] Within large-scale genetic studies, such as the FinnGen study, it is operationally identified through specific International Classification of Diseases (ICD) codes, notably ICD10 N72, ICD9 616, and ICD8 620, and designated by the phenotype identifier N14_INFCERVIX. [1] This condition is distinct from other cervical phenotypes like ectropion, which describes a benign eversion of the columnar epithelium, highlighting cervicitis's primary characteristic as an inflammatory process rather than a structural variation. [1] The term "cervicitis" itself directly translates to inflammation of the cervix, serving as a foundational concept in gynecological pathology. [3]
Classification Systems and Nosology
The classification of cervicitis primarily relies on established nosological systems, particularly the International Classification of Diseases (ICD) codes, which categorize it as an "Inflammatory disease of cervix uteri". [1] This categorical approach facilitates standardized data collection and epidemiological research, as demonstrated by its use in large biobank studies like FinnGen and the Estonian Biobank for identifying cases and controls. [1] While these ICD-based definitions provide a broad classification, studies acknowledge that such reliance on administrative codes can introduce heterogeneity due to variations in coding practices across different healthcare systems. [1] The concept of "cervicitis controls" in genetic research further refines its classification by explicitly excluding other inflammatory diseases of the female genital tract (ICD10 codes N70-N77), ensuring a more specific and focused study population. [1]
Diagnostic and Operational Criteria
Diagnostic criteria for cervicitis, particularly in large genetic association studies, are operationalized through the application of specific ICD codes: ICD10 N72, ICD9 616, and ICD8 620. [1] These codes serve as the primary measurement approach for case ascertainment, distinguishing individuals with cervicitis from control groups that are explicitly defined by the absence of these and related inflammatory conditions. [1] While these criteria enable large-scale data analysis, the research notes that relying solely on ICD codes may lack the granularity of more detailed clinical information, such as Human Papillomavirus (HPV) status or specific histopathological features, which could offer deeper insights into its etiopathogenesis and potential subtypes. [1] Future studies are encouraged to evaluate detected genetic loci in relation to these more specific clinical and pathological biomarkers to further elucidate the role of genetic factors in cervical pathology. [1]
Genetic Predisposition and Host Immunity
Cervicitis susceptibility is influenced by an individual's genetic makeup, including inherited variants and polygenic risk factors. Host genetic factors are known to play a role in the risk of Chlamydia trachomatis-related infertility, which is often preceded by cervicitis, suggesting genetic modulation of the immune response to this common pathogen. [4] Specific genetic variants, such as single-nucleotide polymorphisms (SNPs), can influence an individual's ability to clear infections or their inflammatory response, thereby predisposing them to or protecting them from cervical inflammation. Studies have also identified genes like HLA-DR, HLA-DQ, and MICA as being associated with cervical preinvasive and invasive disease, indicating a role for immune system genes in cervical health. [5]
Beyond direct immune response, human genetic variants can impact the composition and diversity of the vaginal bacteriome, which is crucial for maintaining cervical health. The intricate balance of vaginal bacterial taxa, characterized by alpha and beta diversity metrics, can be influenced by the host genome. [6] Dysbiosis in this microbial community, potentially driven by genetic predispositions, can create an environment conducive to inflammation and infection, contributing to the development of cervicitis. The combined effect of multiple genetic loci, rather than single Mendelian forms, likely contributes to the overall polygenic risk for such complex inflammatory conditions.
Environmental Exposures and Lifestyle Factors
Environmental and lifestyle factors are significant drivers of cervicitis, primarily through the introduction of pathogens and direct irritation of cervical tissues. Sexually transmitted infections (STIs), such as Chlamydia trachomatis, are well-established causes, with host genetic risk factors influencing the outcome of such infections. [4] Engaging in certain "risky behaviors," like having a higher number of sexual partners, is identified as an environmental risk factor that can increase exposure to infectious agents and subsequent cervical inflammation. [5]
Beyond infectious agents, other environmental exposures and lifestyle choices contribute to cervicitis. For example, a lifetime smoking index has been identified as a risk factor for cervical disease, suggesting that chemical irritants or systemic effects of smoking can exacerbate cervical inflammation. [5] Additionally, the use of oral contraceptives represents a medication effect that can interact with an individual's genotype and influence reproductive health, potentially affecting cervical susceptibility to inflammation. [7] These factors collectively disrupt the cervical environment, making it more vulnerable to inflammatory processes.
Gene-Environment Interplay and Developmental Influences
The development of cervicitis often arises from complex gene-environment interactions, where an individual's genetic predisposition is modulated by external factors. For instance, genetic effects can exhibit sex-specific differences, and gene-environment interactions have been found to be an efficient way to test for such effects. [8] Interactions between genotype and variables like sex, oral contraceptive use, and body mass index (BMI) can significantly influence health outcomes, suggesting that genetic susceptibility to cervical inflammation may be contingent upon these environmental or physiological states. [7]
Early life influences and epigenetic mechanisms also contribute to cervical health and disease susceptibility later in life. Developmental factors such as gestational age, birth BMI, and early growth have been considered in genome-wide association analyses, indicating that early life conditions can program an individual's physiology in ways that might impact inflammatory responses. [7] Furthermore, epigenetic modifications, including DNA methylation and histone marks, play a critical role in regulating gene expression and immune function in cervical tissues. [5] These modifications, influenced by both genetic background and environmental exposures, can alter the susceptibility of cervical cells to inflammation and infection over time. Factors related to reproductive function, such as age at menarche and menopause, also represent age-related and hormonal influences that can modulate the cervical environment and its vulnerability to cervicitis. [9]
Biological Background of Cervicitis
Cervicitis is an inflammatory condition affecting the cervix uteri, a critical component of the female reproductive system. [1] This condition is characterized by an inflammatory response within the cervical tissue, which can disrupt the normal physiological state and cellular functions of the cervix. [1] While the exact etiology can vary, host genetic factors are known to modify an individual's susceptibility to this and other cervical phenotypes, influencing the body's homeostatic mechanisms and compensatory responses to potential pathogens or irritants. [1] Understanding the intricate biological mechanisms underlying cervicitis is crucial for comprehensive insights into cervical health and pathology.
Genetic Predisposition and Regulatory Networks
Genetic mechanisms play a significant role in determining an individual's vulnerability to cervicitis. Genome-wide association studies (GWAS) have identified specific genetic loci associated with cervicitis, including variants in the 2q13 region, such as rs1049137. [1] This region is linked to the expression of the PAX8 gene and its antisense RNA, PAX8-AS1, which are essential biomolecules involved in the development of the female genital system and may also influence cellular proliferation within cervical tissues. [1] Such genetic variations can affect gene expression patterns and regulatory networks, thereby modulating the cervical environment and its susceptibility to inflammation.
Further genetic analyses have pinpointed other candidate genes implicated in cervical conditions, including CLPTM1L on chromosome 5 and CDC42 on chromosome 1p36.12. [1] Variants within the intron of CDC42, such as rs2268177, have been identified, and colocalization analyses indicate their association with CDC42 expression. [1] Additionally, the long non-coding RNAs CDC42-AS1 and LINC00339 are also prioritized as candidate genes due to their colocalization with GWAS signals in trait-relevant tissues, suggesting their involvement in complex regulatory networks that impact cervical biology. [1] LINC00339 has been observed to promote cell proliferation, migration, and invasion in various cancer contexts, indicating its potential role in cellular growth and pathological processes within the cervix. [10]
Immune System and Autoimmune Associations
The immune system is a central player in the pathophysiology of cervicitis, with genetic variations in the Human Leukocyte Antigen (HLA) region being particularly influential. [1] Key biomolecules like HLA-DRB1 and HLA-B are critical for presenting antigens to T-cells, thereby orchestrating the adaptive immune response against pathogens, including human papillomavirus (HPV), which is a significant factor in cervical pathology. [1] Genetic associations in this region highlight how individual immune profiles can influence the efficacy of the immune response and the overall susceptibility to inflammatory diseases of the cervix.
Moreover, studies suggest a shared genetic predisposition between cervical conditions and certain autoimmune diseases, such as psoriasis and thyroiditis. [1] This implies that specific combinations of HLA alleles or other immune-related genes, like GSDMB, might predispose individuals to both chronic inflammation in the cervix and systemic immune dysregulation. [1] These systemic consequences underscore the complex interconnections between localized cervical inflammation and broader immune regulatory networks, potentially influencing the body's compensatory responses to persistent immunological challenges and contributing to the development or persistence of cervicitis.
Cellular Pathways and Disease Progression
The molecular and cellular pathways underlying cervicitis involve intricate regulatory networks that govern cellular functions within cervical tissue. Candidate genes such as CDC42 are implicated in these pathways, with genetic variants colocalizing with its expression, suggesting an impact on its function. [1] The coordinated action of critical proteins and regulatory elements within these pathways is essential for maintaining normal cellular functions and responding effectively to pathological conditions in the cervix. [1] Disruptions in these signaling pathways, potentially modulated by genetic variants, could impair the cervix's ability to maintain homeostasis or effectively resolve inflammation.
The observed genetic overlap between cervicitis, cervical dysplasia, and cervical cancer further highlights shared pathophysiological processes. [1] Genetic factors that influence cellular proliferation, apoptosis, or immune evasion, such as those associated with PAX8 or CLPTM1L, may play a dual role in both inflammatory responses and the early stages of neoplastic transformation. [1] This intricate connection suggests that understanding the molecular changes and regulatory networks involved in cervicitis provides crucial foundational knowledge for comprehending the broader spectrum of cervical biology and pathology, including the progression towards more severe conditions.
Genetic Regulation of Cervical Cellular Processes
The development and persistence of cervicitis involve intricate genetic regulatory mechanisms that influence cellular function and tissue homeostasis. Specific genetic variants, such as rs1049137, rs12611652, rs6866294, and rs36214159, have been identified as significantly associated with cervicitis, suggesting their involvement in modulating cellular responses to inflammatory stimuli. [1] These variants may impact the expression or function of nearby genes, potentially altering receptor activation or downstream intracellular signaling cascades essential for maintaining cervical health. For instance, variants overlapping with transcription start site (TSS) flanking regions, like rs1015753 in HeLa cells, or with regulatory enhancer elements, suggest a direct role in gene regulation by influencing the binding of transcription factors and the overall transcriptional output. [1]
Long noncoding RNAs (lncRNAs) also play a critical regulatory role; for example, LINC00339 has been shown to promote cell proliferation, migration, and invasion in other cancer types by acting as a sponge for microRNAs, such as miR-145, miR-148a-3p, and miR-378a-3p, thereby modulating gene expression via post-transcriptional regulation. [1] The expression of LINC00339 itself can be induced by transcription factors like SP1, further highlighting the hierarchical regulation of these pathways. [11] Another gene, CLPTM1L, whose upstream region overlaps with a TSS in HeLa cells, also points to the importance of precise gene regulation in cervical biology. [1] Dysregulation of these gene regulatory mechanisms can lead to an imbalance in cellular processes, contributing to the inflammatory state characteristic of cervicitis.
Immune and Inflammatory Signaling Pathways
Inflammation in the cervix is significantly influenced by immune signaling pathways, with host genetics playing a crucial role in modulating the immune response. Genes like HLA-DRB1 are central to immune recognition and antigen presentation, and their genetic variants can impact the effectiveness of the immune system in clearing pathogens or resolving inflammation. [1] Another key player is GSDMB (Gasdermin B), which is involved in pyroptosis, a type of programmed cell death that is highly inflammatory. [1] A specific splice variant, rs11078928, has been shown to abolish the pyroptotic activity of the GSDMB protein, potentially altering the cellular response to infection or damage and influencing the resolution or perpetuation of inflammation. [1]
The region encompassing GSDMB has also been linked to various inflammatory and autoimmune conditions, including asthma, inflammatory bowel disease, multiple sclerosis, primary biliary cholangitis, and rheumatoid arthritis, underscoring its broad involvement in immune-mediated pathologies. [1] Furthermore, systemic inflammatory diseases and autoimmune conditions are associated with an increased risk of high-grade cervical dysplasia and cervical cancer, suggesting a shared mechanistic basis involving dysregulated immune signaling and inflammatory feedback loops [1] These interactions highlight how systemic immune dysregulation can contribute to localized cervical inflammation and potentially impact disease progression.
Cellular Proliferation, Migration, and Developmental Mechanisms
The integrity and function of cervical tissue rely on tightly controlled cellular proliferation, migration, and developmental pathways. PAX8 (Paired Box 8) and its antisense RNA, PAX8-AS1, exhibit a dual role in cervical biology, being important for the development of the female genital system and potentially enhancing the proliferation of tumor cells. [1] This suggests that dysregulation in PAX8 signaling can contribute to abnormal cell growth, a hallmark of both inflammatory and neoplastic conditions. Similarly, CDC42 (Cell Division Cycle 42), a small GTPase, is known to regulate cell proliferation, migration, and invasion, and its altered expression is observed in cervical cancer. [1] These intracellular signaling cascades, often initiated by receptor activation, dictate cellular fate and behavior, impacting tissue repair, remodeling, and susceptibility to chronic inflammation.
The long noncoding RNA LINC00339 also contributes to cellular proliferation and invasion, as observed in other cancers, by modulating specific molecular axes. [1] Such regulatory mechanisms can influence the biosynthesis of components required for rapid cell division or the catabolism of cellular structures during migration. The WNT4 gene, located at the 1p36.12 locus, is another critical component in gynecological development, and its dysregulation could contribute to pathological changes in cervical tissue. [1] Aberrant control over these developmental and proliferative pathways can lead to an environment conducive to chronic inflammation and potentially contribute to the progression from cervicitis to more severe conditions like dysplasia.
Interconnected Genetic Networks and Disease Progression
Cervical pathologies, including cervicitis, dysplasia, and cancer, are not isolated conditions but are linked through shared genetic backgrounds and intricate pathway crosstalk. Genome-wide association studies (GWAS) have revealed significant genetic overlap and correlations between these distinct cervical phenotypes, indicating that common underlying genetic susceptibilities influence the spectrum of cervical disease. [1] This systems-level integration suggests that pathway dysregulation in one condition can predispose individuals to others, with genetic variants influencing the hierarchical regulation of multiple interconnected biological networks.
Colocalization analyses further refine this understanding by linking GWAS association signals with expression quantitative trait loci (eQTLs), providing insights into how genetic variants impact gene expression in trait-relevant tissues, such as the oesophagus mucosa, which shares cellular and gene expression similarities with the cervix. [1] For instance, CDC42, CDC42-AS1, and LINC00339 show colocalization with cervical cancer GWAS signals, highlighting their potential roles in a broader phenomic network that encompasses cervicitis. [1] While human papillomavirus (HPV) infection initiates cervical cancer development, host genetics significantly influences its progression and prognosis, underscoring the importance of these intrinsic regulatory and signaling networks in determining an individual's susceptibility and the emergent properties of cervical pathology. [1]
Large-Scale Biobank Investigations and Genetic Discoveries for Cervicitis
Large-scale cohort studies leveraging population-based biobanks have significantly advanced the understanding of cervicitis at a population level. For instance, a comprehensive meta-analysis combined data from the Estonian Biobank (EstBB), encompassing 92,042 women, and the FinnGen study, which included up to 112,951 Finnish female individuals from its R5 release. [1] These studies utilized detailed electronic health records and genotyping data, defining cervicitis cases based on International Classification of Diseases (ICD) codes (N72, 616, 620), identifying 19,285 cases in EstBB and 1,093 cases in FinnGen. [1] This approach allowed for robust genetic association analyses, revealing several genome-wide significant variants linked to cervicitis, such as rs1049137, rs12611652, rs6866294, and rs36214159, thereby clarifying the genetic background of this benign cervical condition. [1] The use of such extensive biobank data provides a foundation for longitudinal follow-up, offering the potential to track temporal patterns and the natural history of cervicitis within these populations, though specific longitudinal findings related to cervicitis progression were not detailed in this particular study. [1]
Epidemiological Prevalence and Genetic Correlates of Cervicitis
The epidemiological assessment of cervicitis, particularly its prevalence patterns, is informed by the substantial case numbers identified in large population cohorts. The combined EstBB and FinnGen datasets revealed a considerable number of cervicitis cases (over 20,000 women), indicating its notable prevalence within these European populations. [1] Beyond direct prevalence, these studies explored the genetic overlap and associations between cervicitis and other cervical phenotypes, as well as broader health conditions. Genetic signals for cervicitis were found to share credible set variants with cervical dysplasia and cancer, suggesting a partially shared genetic susceptibility across these conditions. [1] Furthermore, phenome-wide association studies (PheWAS) using genetic risk scores for cervical cancer demonstrated associations with increased risk of dysplasia, viral warts, and diseases with suspected autoimmune etiologies like thyroiditis and psoriasis, highlighting potential broader genetic and immunological predispositions that might also influence cervicitis. [1]
Methodological Approaches and Cross-Population Perspectives in Cervicitis Research
Population studies on cervicitis employ rigorous methodologies, often relying on large-scale genome-wide association studies (GWAS) with mixed logistic regression models, adjusting for factors like year of birth and principal components to account for population structure. [1] The large sample sizes from biobanks like EstBB and FinnGen contribute significantly to the statistical power and representativeness within their respective populations. However, a key methodological limitation highlighted is the reliance on relatively simple phenotype definitions based solely on ICD codes, which could introduce heterogeneity due to variations in coding practices across healthcare systems. [1] While the meta-analysis represented a step towards multi-ancestry GWAS, it acknowledged a small number of non-European samples, limiting the generalizability of findings, especially for populations with a high prevalence of cervical malignancy. [1] Future research necessitates including additional Black and Asian populations to improve the transferability of genetic risk scores and enhance understanding of ancestry-specific effects and geographic variations in cervicitis susceptibility. [1]
