We investigated the associations between an important single nucleotide polymorphism (SNP) in UMOD, that is rs12917707-G>T, and estimated glomerular filtration rate (eGFR), BP and cardiac organ damage as determined by echocardiography in patients with arterial hypertension.Methods:A cohort of 1218 treated high-risk patients (mean age 58.5 years, 83\% men) with documented cardiovascular disease (81\% with coronary heart disease) was analysed.Results:The mean values for 24-h SBP and DBP were 124.714.7 and 73.9 +/- 9.4mmHg; mean eGFR was 77.5 +/- 18.3ml/min per 1.73m(2), mean left ventricular ejection fraction was 59.3 +/- 9.9\% and mean left ventricular mass index in men and women was 53.9 +/- 23.2 and 54.9 +/- 23.7g/m(2.7) with 50.4\% of patients having left ventricular hypertrophy. A significant association between rs12917707 and eGFR was observed with T-allele carriers showing significantly higher eGFR values (+2.6ml/min per 1.73m(2), P=0.006) than noncarriers. This SNP associated also with left atrial diameter (P=0.007); homozygous carriers of the T-allele had smaller left atrial diameter (-1.5mm) than other genotype groups (P=0.040). No significant associations between rs12917707 and other cardiac or BP phenotypes were observed.Conclusions:These findings extend the previously documented role of UMOD for renal function also to treated high-risk patients with arterial hypertension and reveal a novel association with left atrial remodelling and thus a potential cardiorenal link modulated by UMOD.}, language = {en} } @article{HuberLeziusReibisetal.2015, author = {Huber, Matthias and Lezius, Susanne and Reibis, Rona Katharina and Treszl, Andras and Kujawinska, Dorota and Jakob, Stefanie and Wegscheider, Karl and V{\"o}ller, Heinz and Kreutz, Reinhold}, title = {A Single Nucleotide Polymorphism near the CYP17A1 Gene Is Associated with Left Ventricular Mass in Hypertensive Patients under Pharmacotherapy}, series = {International journal of molecular sciences}, volume = {16}, journal = {International journal of molecular sciences}, number = {8}, publisher = {MDPI}, address = {Basel}, issn = {1422-0067}, doi = {10.3390/ijms160817456}, pages = {17456 -- 17468}, year = {2015}, abstract = {Cytochrome P450 17A1 (CYP17A1) catalyses the formation and metabolism of steroid hormones.
