Analysis of association of rs9536314 of the KL gene with anthropometric and biochemical indicators in men of Novosibirsk (West Siberia)
Abstract
Purpose of the study. To determine the frequency of the rs9536314 (F325V) polymorphism of the KL gene and the association of this variant with a number of biochemical and anthropometric parameters in men of the study group and in the Caucasian population of Western Siberia. Materials and methods. The study group (69 men, average age 61.2 ±11.5 years) was randomly formed from a sample of persons who applied to the clinic and polyclinic of NIITPM - a branch of the ICG SB RAS and GBUZ NSO Hospital of war veterans No. 3 (178 men, aged 50-65 years old and over 80 years old). The population group was randomly selected (219 people) from the sample surveyed within the framework of the International Multicenter Project "Risk Factors for Cardiovascular Diseases in Eastern Europe" HAPIEE (9360 participants, 45–69 years old, mean age 53.8±7 years old, Caucasians > 90 %). Biochemical parameters were determined by standard enzymatic methods. Serum concentration of Klotho protein was measured by ELISA. Genomic DNA was amplified by polymerase chain reaction in a standard reaction mixture and further digested with TaqI B restriction enzyme. Results. The frequency of genotypes (TT, TG, and GG) and alleles (T and G) rs9536314 of the KL gene in the study group corresponds to the data in the population of Western Siberia, as well as the population of Western and Eastern Europe. There were no statistically significant differences in the mean values of the studied clinical and biochemical parameters depending on the rs9536314 genotypes of the KL gene in the study group and in the population. In the study group, the level of Klotho protein in the blood and the glomerular filtration rate in men with coronary heart disease and arterial hypertension did not differ in the autosomal dominant and autosomal recessive models for the rs9536314 KL gene. Conclusion. Thus, the frequency of the rs9536314 polymorphism of the KL gene in the study group corresponds to the frequency of the rs9536314 polymorphism of the KL gene in the Caucasian population of Western Siberia. Biochemical and anthropometric parameters, as well as the Klotho protein, do not have statistically significant differences depending on the genotypes of rs9536314 of the KL gene in the examined men.
