Résumé
BACKGROUND AND AIMS: Genome-wide linkage analysis studies reported the importance of the long arm of chromosome 13 in systolic blood pressure regulation. Therefore, isolating a genetic variant related to this chromosomal region could be challenging. Klotho KL-VS allele is located on this chromosomal region and its relationships with cardio-vascular risk factors need extensive investigations. The aim of the present study is to examine whether the klotho KL-VS genotype is associated with cardio-vascular risk factors, more particularly hypertension, in two independent cohorts. A secondary objective was to investigate relationships with antihypertensive treatment, arterial stiffness and carotid artery parameters. METHODS AND RESULTS: A total of 1023 French individuals were genotyped for klotho KL-VS. Participants were part of the French ERA and STANISLAS cohorts. In both cohorts, klotho KL-VS/KL-VS genotype was significantly associated with lower systolic blood pressure and pulse pressure when compared to homozygous and heterozygous more frequent (WT) allele carriers (p=0.003 and p
