Association of single-nucleotide polymorphisms from 17 candidate genes with baseline symptom-limited exercise test duration and decrease in duration over 20 years: the Coronary Artery Risk Development in Young Adults (CARDIA) fitness study.

ABSTRACT:

Background

It is not known whether the genes involved with endurance performance during young adulthood are also involved with changes in performance. We examined the associations of gene variants with symptom-limited exercise test duration at baseline and decrease in duration over 20 years.

Methods and results

A total of 3783 (1835 black, 1948 white) and 2335 (1035 black, 1300 white) participants from the Coronary Artery Risk Development in Young Adults study were included in the baseline and 20-year models, respectively. Two hundred seventeen single-nucleotide polymorphisms (SNPs) in black participants and 171 in white participants from 17 genes were genotyped. In blacks, 5 SNPs in the ATP1A2, HIF1A, NOS3, and PPARGC1A loci tended to be associated (P<0.05) with baseline du
