Intergenic variant in the SLC2A9 urate-transporter locus — the C allele is associated with lower serum uric acid levels and reduced gout risk
Intronic variant in SLC12A5 reducing KCC2 potassium-chloride cotransporter function, shifting GABA signaling from inhibitory to excitatory and increasing risk for depression and anxiety
Intergenic GWAS locus upstream of homeobox genes HOXA10 and HOXA11 that may influence their regulation; carrying the A allele is associated with increased risk of endometriosis, particularly moderate-to-severe disease
Intronic variant in IL2RA intron 1 that creates an estrogen-responsive enhancer element — the risk C allele allows estrogen receptor alpha binding and increases IL2RA transcription, altering T-regulatory cell function and autoimmune disease susceptibility
Intergenic variant near SLC30A1 (ZnT1), the primary basolateral zinc exporter in intestinal enterocytes; the A allele is markedly less common in East Asian populations (7.6%) than in European (49.4%) or African (42.7%) populations, suggesting population-specific selective pressure on zinc transport efficiency.
Regulatory variant that increases sortilin expression, lowering LDL cholesterol and cardiovascular risk
Intronic variant near the TRAF3IP2 locus (annotated in IPCEF1 at chr6q25.2 by dbSNP, 43 Mb distal) that was genotyped alongside TRAF3IP2 coding variants in SLE studies; the A allele is independently associated with SLE susceptibility (OR=1.73, P=0.046) and SLE pericarditis in the Ciccacci 2013 Italian cohort — completing the three-SNP TRAF3IP2/locus panel
Sodium/potassium/calcium exchanger that regulates melanin production in skin cells
Loss-of-function variant in phosphodiesterase 3B — carriers have enhanced cAMP-mediated lipolysis, higher HDL cholesterol, lower triglycerides, and reduced cardiovascular disease risk
Intronic variant in the ATP2B1 calcium pump gene; the common G allele reduces PMCA1 expression in vascular tissue, impairing calcium efflux and raising blood pressure — one of the most replicated blood pressure GWAS loci across Asian and European populations
