Additional Evidence Fails to Associate Variation in KCNE4 With Equine Anhidrosis. A prior genome-wide association (GWA; N = 200) including Thoroughbreds and stock horses implicated chromosome 6 (NC_009149.3) in owner-reported equine anhidrosis. A missense variant in KCNE4 (NC_009149.3:g.11813731A>G) was proposed as a risk allele, although its association with anhidrosis was not reported. Variant annotation and protein modelling in the original study suggested the G allele conferred risk. We reported no association of the G allele with anhidrosis in 50 horses phenotyped by an intradermal terbutaline sweat test (ITST); all horses produced sweat regardless of genotype. ...
