One of the leading causes of death in the world are cardiovascular diseases, among which coronary artery disease (CAD) is the most common one. It occurs as a result of narrowing of the arteries which supply blood to the heart due to a theroma plaque formation. This kind of heart disease can be considered as a multifactorial one as genetic and environmental factors are involved in its incidence. The already conducted studies have investigated the relationship between some of polymorphisms in different loci and CAD with the aim of on-time diagnosis of this disease, which may lead to its prevention and appropriate treatment. The aim of this study was to examine the association of tRNA Thr 15927 G A mutation with the risk of CAD incidence to offer programs for early diagnosis and treatment of this disease in Iran. Fifty patients with CAD were included in the patient group, and fifty healthy participants were selected for the control group. 5mL of peripheral blood samples drawn from subjects in patient and control groups were collected in the tubes containing Ethylenediaminetetraacetic acid (EDTA). After DNA extraction from blood with the employment of DNA extraction kit, its quality and quantity were measured using electrophoresis and NanoDrop devices, respectively. Then, the isolated DNA with the implementation of  amplification-refractory mutation system (ARMS)  and restriction fragment length polymorphism (RFLP) techniques was examined to determine and evaluate the target polymorphism in the intended locus. Sequencing method was also used to confirm the findings. To this end, 4 samples were randomly selected and sequenced.In the control group, 6 screened patients had the mutation while the others did not. Similar result was observed in the patient group. The findings of the present study reveal that there was not any significant relationship between tRNAThr 15927G A mutation and risk of CAD incidence.
