Vitamin D binding protein variant that determines VDBP isoform, affecting vitamin D transport, bioavailability, and supplementation response

Second functional variant in glutathione S-transferase Pi 1, reducing enzyme activity to ~80% of normal and defining key GSTP1 haplotypes that affect detoxification capacity and cancer susceptibility

Common coding variant in the HNF1A transcription factor dimerization domain that modestly reduces beta-cell function and transactivation activity, raising LDL cholesterol and lowering CRP, while increasing type 2 diabetes risk in normal-weight individuals and accelerating diabetes onset in MODY3 carriers

SNCA 3′-region variant in the extended 3′ UTR that affects alpha-synuclein mRNA stability and expression, consistently associated with Parkinson's disease risk across Asian and European populations

Intronic variant in ZMYM4, a chromatin-remodeling transcription factor whose locus is associated with body fat distribution (waist-hip ratio, BMI-adjusted waist circumference) and immune regulation; rare deleterious ZMYM4 variants are enriched in severely obese children.

Deep intronic IL6R variant associated with atopic dermatitis risk and systemic IL-6 signaling, with the G allele elevating eczema risk while reducing inflammatory cardiovascular markers through altered IL-6 receptor expression or splicing

Intronic ABCA1 variant associated with population differences in HDL cholesterol capacity; the A allele tags reduced cholesterol efflux activity and lower HDL in carriers

Intronic variant in IFNL4 — the strongest host genetic predictor of hepatitis C spontaneous clearance and treatment response, controlling interferon lambda antiviral immunity

Rare protective missense variant in the NF-kB inhibitor zeta gene that reduces Th17-driven autoimmune thyroid inflammation and lowers hypothyroidism risk

Near-gene upstream variant in IL6 associated with hepatocellular carcinoma risk through altered interleukin-6 regulation — an independent inflammaging signal
