Pain
Pain is a complex, subjective, and often distressing sensory and emotional experience associated with actual or potential tissue damage. It serves as a fundamental protective mechanism, alerting an individual to injury, illness, or potential harm, thereby prompting withdrawal, rest, or seeking medical attention. This universal experience is influenced by biological, psychological, and social factors, making its perception highly individual.
At its biological core, pain involves the intricate processing of noxious stimuli by the nervous system, a process known as nociception. However, the experience of pain extends beyond mere sensation, encompassing emotional and cognitive dimensions. Research highlights that individual differences in pain sensitivity, perception, and susceptibility to chronic pain conditions have a significant genetic component. Genome-wide association studies (GWAS) have been instrumental in uncovering specific genetic loci and single nucleotide polymorphisms (SNPs) associated with various pain phenotypes. These include associations with chronic widespread pain[1], back pain[2], multisite chronic pain[3], pain sensitivity[4], and various forms of neuropathic pain, such as diabetic neuropathic pain[5], neuropathic pain following total joint replacement[6], and neuropathy in cancer patients[7]. Genetic variations have also been linked to specific conditions like dysmenorrhea [8], chronic musculoskeletal pain[9], and pain experience in specific populations, such as associations with pleiotrophin polymorphism in Japanese adults[10]. These studies suggest that putative causal genes are often expressed in brain tissues and are implicated in neurogenesis, neuronal development, neural connectivity, and cell-cycle processes [4].
Clinically, pain is broadly categorized into acute pain, which is typically temporary and resolves with healing, and chronic pain, which persists beyond the normal healing period, often lasting for months or years. Chronic pain represents a major healthcare challenge, impacting millions globally and encompassing a diverse range of conditions. Understanding the genetic architecture of pain is crucial for developing personalized medicine approaches, allowing for more targeted diagnostics, preventative strategies, and effective treatments. Furthermore, studies have underscored significant sex differences in the prevalence and genetic underpinnings of chronic pain, with a recognized need for sex-stratified genetic analyses to fully capture these biological distinctions[11].
The social importance of pain cannot be overstated. Chronic pain significantly diminishes an individual’s quality of life, affecting physical function, mental health, and social participation. It is a leading cause of disability worldwide and imposes a substantial economic burden through healthcare costs, lost productivity, and reduced quality of life. Advancements in understanding the genetic basis of pain offer hope for mitigating this burden by paving the way for novel therapeutic targets, improved pain management strategies, and ultimately, enhanced well-being for those affected.
Limitations
Section titled “Limitations”Understanding the genetic architecture of pain is a complex endeavor, and current research faces several inherent limitations that influence the interpretation and generalizability of findings. These limitations span methodological and statistical constraints, the inherent complexity of pain phenotypes, and the challenges in fully accounting for genetic and environmental interactions.
Methodological and Statistical Constraints
Section titled “Methodological and Statistical Constraints”Many pain genetics studies have historically utilized small sample sizes, frequently employing candidate gene or gene panel approaches[12]. While these studies contribute to initial hypotheses, their limited statistical power can hinder the detection of true genetic associations and robustly characterize the genetic landscape of pain sensitivity[12]. Although larger genome-wide association studies (GWAS) have emerged, particularly from extensive cohorts such as the UK Biobank, the overall number of comprehensive GWAS on the diverse spectrum of pain phenotypes remains restricted[12]. Such power limitations can also contribute to issues like genomic inflation and necessitate large-scale meta-analyses to reliably identify genetic effects [13].
A critical aspect of genetic research is the replication of initial findings by independent investigators, ideally across larger and more diverse samples, to confirm novel genetic associations [14]. Furthermore, current genotyping platforms do not encompass all known common genetic variations throughout the human genome, potentially leading to an incomplete capture of genetic contributions and an increased risk of false discoveries [14]. This partial coverage of genetic variation can impact the accuracy of heritability estimates and obscure a complete understanding of the genetic basis of pain.
Phenotypic Complexity and Generalizability
Section titled “Phenotypic Complexity and Generalizability”Pain manifests as a highly complex and variable phenotype, characterized by substantial interindividual differences in sensitivity and perception[12]. Research often focuses on distinct types of pain, such as neuropathic pain, acute post-surgical pain, or dysmenorrhea, each potentially possessing unique genetic underpinnings and physiological responses[8]. The diverse nature of pain experiences, including its documented correlations with psychiatric conditions, personality traits, autoimmune disorders, anthropometric measures, and circadian rhythms, highlights the significant challenges in precisely defining and measuring pain phenotypes for genetic investigation[12].
Another substantial limitation in pain genetics is the restricted generalizability of research findings. Many studies have been predominantly conducted in populations of European ancestry[14]. However, pain responses, including the efficacy of analgesics and underlying genetic variations, are known to differ significantly across various ethnic populations[14]. Consequently, results obtained from one population may not be directly applicable or transferable to others, underscoring the imperative for genetic studies to include diverse ancestral backgrounds to ensure broader applicability and a more comprehensive understanding of pain’s genetic architecture across human populations[14].
Unexplained Genetic and Environmental Influences
Section titled “Unexplained Genetic and Environmental Influences”While single nucleotide polymorphism (SNP)-based heritability estimates for chronic pain phenotypes typically range from approximately 7% to 12% on the liability scale, a considerable portion of the genetic variance remains unexplained, contributing to the phenomenon of “missing heritability”[13]. This gap suggests that current genetic models may not fully account for all contributing genetic factors, such as rare variants, structural variations, or complex epistatic interactions. Additionally, genetic association studies primarily identify statistical correlations, emphasizing the ongoing need for further research to elucidate the precise biological mechanisms through which identified genetic loci influence pain perception and processing, particularly when candidate genes lack clear functional annotation[14].
The development and experience of pain are not solely determined by genetic factors but are also profoundly shaped by environmental influences and intricate gene-environment interactions[13]. For instance, observed sex-related differences in pain prevalence and its genetic architecture can be mediated through mechanisms such as sex-differential gene expression, epigenetic modifications like methylation, hormonal influences, and environmental factors that are strongly correlated with sex[3]. A holistic understanding of pain therefore requires integrating genetic discoveries with environmental exposures and their complex interplay to fully unravel the multifaceted biological pathways that contribute to individual variability in pain susceptibility and experience.
Variants
Section titled “Variants”Genetic variations contribute significantly to individual differences in pain perception and the risk of developing chronic pain conditions. This section details several single nucleotide polymorphisms (SNPs) and their associated genes that have been implicated in pain pathways, ranging from direct sensory transduction to broader neurological and stress responses.
One group of variants impacts genes crucial for neuronal function and stress regulation. The rs11172113 variant in the LRP1gene, which encodes the Low-density lipoprotein receptor-related protein 1, is relevant becauseLRP1 plays a vital role in neuronal survival, synaptic function, and inflammatory processes within the nervous system. Alterations in LRP1activity could influence neural plasticity and the brain’s response to injury, thereby affecting chronic pain development. Similarly, variants likers1050316 and rs3790455 in the MEF2D gene, encoding Myocyte Enhancer Factor 2D, are important as MEF2Dis a transcription factor essential for neuronal development and synaptic plasticity. Research highlights that pathways like “neurogenesis” and “synaptic signaling” are significantly associated with pain sensitivity, suggesting thatMEF2Dvariants could modulate pain through these fundamental neuronal processes[12]. Furthermore, the rs17689882 variant, located near CRHR1, MAPT-AS1, and LINC02210-CRHR1, is of interest due to CRHR1’s central role in the body’s stress response system. The Corticotropin Releasing Hormone Receptor 1 mediates responses to stress, and disruptions can impact anxiety and depression, both of which are strongly correlated with chronic pain states[3]. The “glucocorticoid receptor signaling pathway,” which CRHR1influences, has been explicitly linked to anxiety and chronic pain, underscoring the potential impact of this variant on pain through stress-related mechanisms[15].
Another set of variants affects genes directly involved in sensory processing and neurotrophic support, which are fundamental to how pain signals are initiated and maintained. Thers10166942 variant near MSL3B and TRPM8 is particularly significant due to the TRPM8 gene, which codes for a well-known cold and menthol receptor. TRPM8is critical for sensing cold temperatures and is implicated in cold allodynia, a type of pain where cold stimuli cause discomfort. Variants inTRPM8can alter the sensitivity of this receptor, potentially influencing an individual’s experience of cold-related pain and contributing to conditions like neuropathic pain[16]. Likewise, the rs12134493 variant near LINC01765 and NGF-AS1is relevant through its potential influence on Nerve Growth Factor (NGF) signaling. NGF is a crucial neurotrophin that promotes neuronal growth and survival, and it is a potent mediator of inflammatory and neuropathic pain. Research highlights that many genes associated with pain are involved in “neuron and brain development, and neuron signaling,” emphasizing the broad impact of neurotrophic factors like NGF on pain pathways[12].
Finally, several variants are found in genes involved in broader cellular processes and stress responses that can indirectly modulate pain. Thers9349379 variant in PHACTR1 (Phosphatase and actin regulator 1) is involved in regulating cell structure and signaling, which could indirectly affect neuronal communication or inflammatory responses. Variants rs11153082 and rs2273621 in FHL5(Four and a half LIM domains protein 5) are part of a family of proteins that regulate transcription and cellular stress responses, potentially influencing pain pathways through their role in cellular adaptation and signaling. Thers547584345 variant in ZMAT3 (Zinc Finger Matrin-Type 3) is noteworthy as ZMAT3is a transcription factor involved in stress responses and apoptosis, processes that are critical in nerve injury and the transition to chronic pain. Given that major depressive disorders are “genetically correlated with pain,” genes involved in general stress and cellular regulation, such asZMAT3 and FHL5, may contribute to this comorbidity [9]. Similarly, variants rs1537375 and rs10757270 in CDKN2B-AS1(Cyclin Dependent Kinase Inhibitor 2B Antisense RNA 1) are found in a long non-coding RNA that influences cell cycle and proliferation, which could play a role in the cellular environment of chronic pain. Lastly, thers13207082 variant near CDCA7P1 and POM121L2(a nuclear pore complex protein) might affect fundamental cellular transport mechanisms, indirectly impacting gene expression and neuronal health relevant to pain. Disruptions in fundamental cellular processes are increasingly recognized as contributors to the complex etiology of chronic pain[12].

Classification, Definition, and Terminology
Section titled “Classification, Definition, and Terminology”Defining Pain and its Core Concepts
Section titled “Defining Pain and its Core Concepts”Pain is precisely defined as a complex, unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage. The International Association for the Study of Pain (IASP) has significantly contributed to standardizing the terminology, providing a comprehensive list of pain terms with definitions and notes on usage[17]. This standardized vocabulary establishes a crucial conceptual framework, ensuring clarity and consistency in clinical practice, research, and communication across various disciplines [17]. Understanding pain extends beyond its sensory input, encompassing its subjective and affective dimensions.
Classification and Phenotypic Subtypes
Section titled “Classification and Phenotypic Subtypes”Pain is broadly classified into distinct categories based on its duration, etiology, and anatomical location, representing a categorical approach to its diverse manifestations. A fundamental distinction exists between acute and chronic pain, with chronic pain typically defined by its persistence for more than three months[18]. Further classification identifies various phenotypic subtypes, including back pain[13], neck or shoulder pain[18], diabetic neuropathic pain[5], dysmenorrhea [8], and multisite chronic pain[3]. These specific classifications are essential for tailoring diagnostic approaches and therapeutic interventions, recognizing the distinct underlying pathophysiology of each pain type.
Beyond duration and location, pain can also be characterized by its context, such as acute post-surgical pain[14]or chronic postoperative pain[19]. The biological processes of nociception—the detection of noxious stimuli—and sensitization, which can lead to the development and maintenance of chronic pain, are critical concepts in understanding the transition from acute injury to persistent pain states[3]. Furthermore, the severity and intensity of pain symptoms are integral to its characterization, influencing clinical assessment and the stratification of individuals in research studies[3].
Operational Definitions and Measurement Criteria
Section titled “Operational Definitions and Measurement Criteria”Operational definitions for pain are crucial for consistent diagnosis and objective measurement in both clinical and research settings, often involving specific criteria and quantitative scales. For example, in studies of acute post-radiotherapy pain, cases were precisely defined as individuals reporting a pain score of 4 or higher, while a reference group included those with a pain score below 4[16]. Similarly, for conditions like neck or shoulder pain, participants are categorized as cases based on self-reported pain in the specified region, often within a defined temporal window, such as the preceding three months[18]. These thresholds and cut-off values provide clear, measurable criteria for identifying and distinguishing different pain populations.
Measurement approaches frequently involve structured questionnaires that assess the presence, anatomical location, and duration of pain, such as inquiring whether pain or discomfort has been experienced for more than three months[18]. These systematic inquiries aid in establishing diagnostic criteria, enabling differentiation between transient and persistent pain conditions. While specific biomarkers for pain are still an evolving area, the recognized interplay between the immune and nervous systems in nociception and sensitization offers insights into the biological underpinnings of chronic pain development[3].
Signs and Symptoms
Section titled “Signs and Symptoms”Clinical Presentation and Phenotypic Spectrum
Section titled “Clinical Presentation and Phenotypic Spectrum”Pain manifests in a wide array of clinical phenotypes, ranging from localized acute discomfort to widespread chronic conditions. Common presentations include specific regional pains such as back pain, knee pain, and neck and shoulder pain, or more generalized forms like multisite chronic pain[12]. Specific conditions like dysmenorrhea involve pelvic pain, while diabetic neuropathic pain and post-total joint replacement neuropathic pain represent distinct neuropathic phenotypes[8]. The severity of pain is highly variable, often described along a spectrum from mild to severe, and can exhibit diurnal patterns in intensity[3].
This diversity in presentation underscores significant inter-individual variability in pain sensitivity and perception[12]. For instance, some individuals report chronic musculoskeletal pain localized to specific regions, while others experience pain “all over the body,” though this diffuse phenotype is less common[9]. Genetic factors are increasingly recognized as contributing to this phenotypic diversity, with genome-wide association studies (GWAS) identifying genes associated with various pain types, including chronic pain, back pain, and dysmenorrhea[12].
Assessment Modalities and Inter-individual Variability
Section titled “Assessment Modalities and Inter-individual Variability”Assessment of pain primarily relies on subjective measures, such as patient-reported questionnaires and standardized measurement scales that quantify intensity and impact[12]. However, objective measures, like the cold pressor test, are also employed to assess individual pain sensitivity[12]. The integration of both subjective and objective data is crucial, given the substantial interindividual variability in how pain is experienced and expressed[12]. Biomarkers, often identified through genetic research, are emerging as potential objective indicators, with studies exploring genetic associations with pain severity and risk factors[13].
Beyond general inter-individual differences, pain presentation and perception can vary by demographic factors. While specific age-related changes are not detailed, the genetic architecture of pain is being explored across different populations, including adolescents[15]. Sex differences are evident in conditions like dysmenorrhea, where pain severity is a key phenotypic trait, and genetic analyses are conducted to understand these specific patterns[8]. The complex interplay of genetic and environmental factors contributes to the unique pain profile of each individual.
Diagnostic Implications and Clinical Correlations
Section titled “Diagnostic Implications and Clinical Correlations”The detailed characterization of pain signs and symptoms holds significant diagnostic value, aiding in the differentiation of various pain conditions and guiding clinical management. Identifying specific pain phenotypes, such as neuropathic pain versus musculoskeletal pain, is critical for accurate diagnosis and selecting appropriate therapies[18]. Certain presentations, like the sudden onset of severe pain or pain accompanied by neurological deficits, can serve as “red flags” indicating serious underlying pathology requiring immediate attention. Genetic insights are beginning to offer prognostic indicators, for example, through the identification of variants near the nerve growth factor locus associated with dysmenorrhea severity[8].
Pain frequently correlates with a range of other health conditions and traits, highlighting complex clinical correlations. Chronic pain, for instance, is often comorbid with major depressive disorder (MDD), sleep disturbances, and obesity[3]. There is also recognized cross-talk between the immune system and nervous system in nociception, with many autoimmune disorders associated with chronic pain and neuroinflammation[3]. Furthermore, chronic pain is a common component of numerous neurological diseases, including Parkinson’s disease, Multiple Sclerosis, and migraines[3]. Understanding these correlations is vital for holistic patient care and developing comprehensive treatment strategies.
Causes of Pain
Section titled “Causes of Pain”Pain is a complex sensation influenced by a multitude of interacting factors, ranging from an individual’s genetic blueprint to their environment and broader health status. Understanding these diverse causal pathways is crucial for comprehending the variability in pain perception and experience.
Genetic Underpinnings of Pain Sensitivity
Section titled “Genetic Underpinnings of Pain Sensitivity”Individual variability in pain sensitivity and perception is substantially influenced by genetics. Genome-wide association studies (GWAS) have identified numerous genetic loci associated with various pain phenotypes, including chronic pain, back pain, knee pain, neck and shoulder pain, migraine, dysmenorrhea, and neuropathic pain , and at Chr8p21.3 (GFRA2) in diabetic neuropathic pain[18]. These genetic findings suggest that alterations in protein synthesis, modification, or the efficiency of signaling pathways, including those involving transcription factor regulation, contribute to the susceptibility and severity of pain.
Inter-Systemic Crosstalk and Metabolic Modulators of Pain
Section titled “Inter-Systemic Crosstalk and Metabolic Modulators of Pain”Pain pathways are not isolated but engage in extensive crosstalk with other physiological systems, notably the immune and metabolic systems. There is significant interaction between the immune system and the nervous system in the processes of nociception and sensitization that lead to chronic pain[3]. This involves immune cells releasing mediators that modulate neuronal excitability and vice versa, creating a complex feedback loop. Metabolic factors also play a critical role, as seen in the comorbidity of obesity and chronic pain, where chronic inflammation and the metabolic activity of adipose tissue can influence pain perception and inflammatory responses[3]. These systemic interactions highlight how integrated physiological networks contribute to the overall pain experience through complex network interactions and emergent properties.
Dynamic Regulation and Neurological Context of Pain
Section titled “Dynamic Regulation and Neurological Context of Pain”The intensity and perception of pain are subject to dynamic regulatory mechanisms, including those influenced by circadian rhythms and broader neurological contexts. Sleep disturbances and a loss of circadian rhythm are frequently observed in individuals experiencing chronic pain, and many chronic conditions, including pain, exhibit diurnal patterns in symptom severity and intensity[3]. This suggests a hierarchical regulation where central nervous system processes and internal biological clocks modulate the experience of pain through mechanisms like post-translational regulation and allosteric control of key proteins. Furthermore, chronic pain is a common component of various neurological diseases, such as Parkinson’s disease, Multiple Sclerosis, and migraines, underscoring the deep integration of pain pathways within the central nervous system’s broader regulatory networks[3].
Pathway Dysregulation and Therapeutic Avenues
Section titled “Pathway Dysregulation and Therapeutic Avenues”Dysregulation within these complex pain pathways represents a core mechanism underlying various chronic pain conditions. Genetic studies have illuminated specific instances of pathway dysregulation, identifying shared genetic factors associated with conditions like back pain[13], chronic musculoskeletal pain[9], and acute post-surgical pain[14]. These findings suggest that alterations in specific genes or their regulatory elements can lead to aberrant signaling, metabolic imbalances, or altered protein function, contributing to pain pathology. Understanding these specific dysregulated pathways and compensatory mechanisms provides critical insights for identifying potential therapeutic targets, offering avenues for developing more effective and personalized pain management strategies.
Pharmacogenetics of Pain
Section titled “Pharmacogenetics of Pain”Understanding the genetic basis of human variations in pain is crucial for elucidating the molecular mechanisms underlying pain sensitivity and individual responses to analgesic drugs , presents significant ethical challenges concerning the use of genetic information. As genetic testing for pain predisposition becomes more feasible, ensuring robust informed consent processes is paramount. Individuals must fully comprehend the potential implications of such tests, including the probabilistic nature of genetic risk and the absence of definitive prognoses, before making decisions about their genetic data.
A critical concern is the potential for genetic discrimination, where individuals identified with genetic predispositions to severe or chronic pain could face adverse treatment in areas like employment, insurance, or even social interactions. Safeguarding the privacy of genetic data related to pain is therefore essential to prevent its misuse. Furthermore, for conditions where genetic factors significantly influence pain experience, the availability of prenatal genetic screening could introduce complex reproductive choices, raising questions about the societal value placed on different levels of pain sensitivity and the ethical boundaries of genetic selection.
Societal Impact and Health Equity
Section titled “Societal Impact and Health Equity”The identification of genetic factors influencing pain severity and susceptibility, such as those implicated in multisite chronic pain or acute post-radiotherapy pain[3], carries substantial social implications, particularly regarding stigma and health equity. While genetic insights could legitimize the experience of chronic or severe pain, potentially reducing the stigma associated with “invisible” illnesses, there is also a risk of creating new forms of labeling or discrimination based on genetic predispositions. This could lead to individuals being viewed through the lens of their genetic risk, rather than their full personhood, affecting social perceptions and support systems.
Furthermore, advancements in genetically informed pain management could exacerbate existing health disparities if access to sophisticated diagnostics or personalized therapies is not equitably distributed. Socioeconomic factors, geographic location, and cultural considerations profoundly influence access to care and the interpretation of pain experiences. Without deliberate policy interventions, vulnerable populations, who often already face barriers to adequate healthcare, could be further marginalized, widening the gap in health outcomes and reinforcing systemic inequalities in pain management globally.
Policy, Regulation, and Research Ethics
Section titled “Policy, Regulation, and Research Ethics”The rapid expansion of genome-wide association studies into various pain conditions, including back pain and adolescent anxiety and pain[13], necessitates robust policy and regulatory frameworks. There is a pressing need for clear guidelines governing genetic testing for pain susceptibility, particularly concerning direct-to-consumer offerings and their clinical integration. Comprehensive data protection regulations are crucial to manage the immense datasets generated from studies involving hundreds of thousands of individuals[20], ensuring participant privacy and preventing unauthorized access or misuse of sensitive genetic information.
Ethical considerations in research are also paramount, demanding stringent protocols for informed consent, data sharing, and the management of incidental findings, especially when dealing with vulnerable populations like adolescents [15]. As genetic insights begin to inform clinical practice, the development of ethical clinical guidelines will be essential to ensure that genetic information is used responsibly and effectively in pain diagnosis and treatment. This also extends to global health perspectives, where equitable resource allocation for research and intervention must be considered to prevent further disparities in pain management across different nations and socioeconomic strata.
