Her, genotype ex interactions had been also observed for three independent loci inside the SELE gene. These findings could have significant public overall health and clinical implications.648 American Journal of Hypertension 26(five) MayCompared with common variants which have been reported previously for other BP-related traits, variants identified in our major analysis each explained a reasonably big proportion of the variation inside the BP salt-sensitivity phenotypes (ranging 0.five .1 ). These benefits highlight the possible utility of examining intermediate phenotypes in genomic study. Furthermore, by supplying sturdy proof of genotype ex interactions, our findings recommend a genomic explanation for observed sex differences in this complex trait. Encoding among the big endothelium-derived vasoactive mediators, the DDAH1 gene is implicated in BP salt sensitivity due to its influence on NO production through the regulation of asymmetrical dimethylarginine (ADMA).21 ADMA,The GenSalt StudyFigure two. Log P values for the genotype ex interactions of 292 single nucleotide polymorphisms in 14 candidate genes and systolic blood pressure (SBP), diastolic blood stress (DBP), and mean arterial stress (MAP) responses to low- (a) and high-sodium (b) interventions. Labeled SNPs had Q 0.05.which has been shown to enhance after salt loading, is inversely linked with NO synthesis and BP.224 DDAH1 metabolizes ADMA to L-citrulline and dimethylamine, playing a important role inside the determination of in vivo ADMA concentration.While preceding research have not implicated DDAH1 gene variants inside the pathogenesis of salt sensitivity, DDAH1 variants happen to be associated with ADMA concentrations plus the increased threat of important BP-related traits, includingAmerican Journal of Hypertension 26(five) May possibly 2013Table 4.
