Genetic Susceptibility in Hidradenitis Suppurativa
Research Guide
What is Genetic Susceptibility in Hidradenitis Suppurativa?
Genetic susceptibility in hidradenitis suppurativa refers to inherited genetic factors and identified loci contributing to disease risk and familial aggregation in HS patients.
Genome-wide association studies reveal heritability in HS families with loci in γ-secretase genes like NICD1/2 implicated in pathogenesis (Pace et al., 2022). Polygenic risk scores and ethnic variations emerge as key areas, supported by systematic genomic reviews covering 114 citations. Over 10 papers from 2011-2023 detail genetic architecture, with van der Zee et al. (2012) providing foundational phenotyping insights cited 201 times.
Why It Matters
Genetic susceptibility insights enable risk prediction for HS family members, guiding early screening in high-risk groups (Pace et al., 2022). Personalized medicine targets γ-secretase pathways, improving treatments for severe phenotypes as seen in familial clusters (van der Zee et al., 2012). Associations with IBD highlight shared genetic risks, informing multidisciplinary care (Huang et al., 2012; Chen and Chi, 2019). These advances shift HS management from symptomatic relief to prevention, reducing morbidity in affected populations.
Key Research Challenges
Identifying Causal Variants
Distinguishing causal genetic variants from associated loci in HS remains difficult due to complex polygenic architecture (Pace et al., 2022). Limited family-based sequencing hinders validation of heritability estimates. Functional studies linking γ-secretase mutations to follicular occlusion are sparse.
Ethnic Variation Mapping
Genomic studies underrepresent non-European populations, obscuring ethnic-specific risk alleles in HS (Pace et al., 2022). Heritability differs across ancestries, complicating polygenic risk score transferability. Larger diverse GWAS are needed for equitable risk prediction.
Translating to Risk Scores
Developing clinically viable polygenic risk scores for HS faces validation gaps in prospective cohorts (van der Zee et al., 2012). Integrating rare variants with common loci challenges scoring accuracy. Clinical trials testing PRS-guided interventions lack scale.
