Synonymous exon 8 variant in perilipin 1 that tags a haplotype associated with fat mobilization efficiency and sex-specific obesity risk

Intronic regulatory variant in FADS2 that tags a 10-SNP haplotype reducing basal FADS1 and FADS2 expression, lowering long-chain PUFA synthesis capacity and arachidonic acid levels; T allele carriers have lower D5D and D6D activity and reduced fasting insulin.

Longevity-associated intronic enhancer variant with 1.9-fold increased probability of reaching age 95

Rare truncating variant in desmoplakin that creates a premature stop codon at position 72, disrupting cardiac desmosomal integrity and predisposing carriers to arrhythmogenic cardiomyopathy with predominantly left ventricular involvement.

CETP promoter variant that raises HDL cholesterol by reducing cholesteryl ester transfer protein activity; A allele carriers show higher HDL-C but mixed cardiovascular outcome evidence.

Missense variant in Toll-like receptor 4 reducing bacterial endotoxin recognition and dampening inflammatory responses

Intronic SMAD3 variant tagging the CAD-protective haplotype where the T allele reduces SMAD3 enhancer activity in arterial smooth muscle cells, lowering TGF-beta-driven vascular remodeling and coronary artery disease risk

Upstream regulatory variant near TCN2 associated with reduced holotranscobalamin levels — the bioactive fraction of circulating vitamin B12 available for cellular uptake

Intronic eQTL in CHRNA5 that modulates alpha-5 nicotinic receptor mRNA expression levels, forming an independent risk signal for nicotine dependence and lung cancer distinct from the Asp398Asn coding variant (rs16969968)

Pathogenic missense variant in the VWF propeptide D2 domain that introduces an aberrant N-glycosylation site, disrupting VWF multimerization and Weibel-Palade body storage; heterozygous carriers have type 2A von Willebrand disease with qualitative VWF deficiency and variable bleeding risk
