A CLCNKA polymorphism (rs10927887; p.Arg83Gly) previously linked to heart failure is associated with the estimated glomerular filtration rate in the RENASTUR cohort.
Individual genotyping of rs10927887 in the two study populations and a third independent heart failure cohort (combined n = 5,489) revealed an additive allele effect on heart failure risk that is independent of age, sex, and prior hypertension (odds ratio = 1.27 per allele copy; P = 8.3 × 10(-7)).
