In Turkey cardiovascular diseases is one of the deadly diseases as all over the world. Thrombosis is a disease with many factors where inherited and acquired factors is acting together or alone. The aim of this study was to evaluate the effect of some cardiovascular, thrombotic risk factors on longevity such as FV 1691 G-A, PT 20210 G-A, MTHFR 677 C-T and ACE I/D and to determine the role of combination of mutations in young and old groups.In our study as a clinical thrombosis of age between 0?18, 362 individual, 70 years and over 209 individual, with 332 individual in the 0?18 age range do not have thrombosis 70 years and over 266 individuals were included. DNA was extracted by classical phenol-clorofrom method and genotyping of FV 1691 G-A, PT 20210 G-A, MTHFR 677 C-T polymorphisms were performed by Real-Time PCR technique. Genotyping of ACE I/D polymorphism, perfect- matched primers used to amplify the target region and agarose gel electrophoresis was performed for the identification of this polymorphism.In the two age groups between healty 8 patient groups FV 1691 G-A, PT 20210 G-A, MTHFR 677 C-T and ACE I/D polymorphisms were not found statistically significant when analyzed one by one. But our study showed that when analyzed together these polymorphisms are thrombotic risk factor in the studied groups.trFV 1691 G-A,PT 20210 G-ATrombozmasterThesis
