Intronic variant in SYCP2L on chromosome 6p24.2; the G allele associates with earlier natural menopause (approximately 0.17 years per allele copy) by influencing expression of a meiosis-specific centromere protein essential for primordial follicle survival

Third independent CTSS-locus atopic dermatitis risk signal from the Budu-Aggrey 2023 GWAS; G allele associated with OR 1.25 for eczema risk through a distinct regulatory mechanism acting on cathepsin S expression in antigen-presenting cells

Gain-of-function variant in the P2X7 receptor that increases ATP-gated pore formation, IL-1β release, and microglial neuroinflammation, associated with mood disorders and chronic pain severity

Intronic/promoter-region ADIPOQ variant where the A allele reduces circulating adiponectin, blunting insulin sensitization and raising cardiovascular and metabolic risk

Intronic CYP2C9 haplotype tag associated with altered warfarin sensitivity and NSAID metabolism in Asian populations

Aryl hydrocarbon receptor variant in the transactivation domain that alters AHR signaling, affecting CYP1A2 inducibility, caffeine metabolism patterns, and circadian clock interactions

Downstream regulatory variant affecting LPL expression and triglyceride clearance — the A allele increases LPL activity and lowers plasma triglycerides

Missense variant in the DNA damage recognition gene XPC that reduces global-genome nucleotide excision repair capacity, affecting recovery from UV-induced damage, exercise-generated oxidative DNA lesions, and environmental carcinogen exposure

Promoter variant that reduces APOC3 expression, associated with lower triglycerides, favorable lipoprotein profiles, and enrichment in centenarians

Pathogenic missense variant in the cytochrome P450 1B1 enzyme that abolishes most enzyme activity, causing primary congenital glaucoma and reduced estrogen hydroxylation capacity
