CARDIOVASCULAR SYSTEM AND MUSCULOSKELETAL CHANGES OF THE SPORTSMEN WITH POLYMORPHISMS OF COL1A1 GENE.

: The purpose of the study of the study is an identification of the extension and impact of polymorphism of COL1A1 gene on cardiovascular system and musculoskeletal state of athletes. 85 people in the ages from 9 to 32 (the average age was 23.2±4.3 years) with polymorphisms rs 1800012 of COL1A1 gene were examined during this investigation. With the help of anthropometry and somatoscopy skeletal abnormalities were established. To cardiohemodynamic investigation was used echocardiography. Polymorphisms of COL1A1 gene analysis was done by polymerase chain reaction method. The study results of polymorphism of COL1A1gene rs 1800012 expansion pointed at the critical extension of heterozygous gene GT in the selected for analysis population however heterozygous gene TT is found only with frequency of 3.5%. Associated trait of genotype TT of polymorphisms of COL1A1gene rs 1800012 involves dolichostenomelia, joints' hypermobility, frequency increase of back bone deflection and as a result rising CT exhaustion level in dysplastic process that is corresponded with abnormality of CT skeleton qualitative composition. Functionary unfavorable genotype TT leads to the changes in heart morphology, major vessels and myocardium relaxation process deflection.
