RESUMEN
Background: Coronary artery disease [CAD] is a multifactorial and heterogenic disease. Recently, genome-wide association studies have reported that rs1333040 [C/T] and rs1004638 [A/T] single nucleotide polymorphisms [SNPs] in the 9p21 locus have very strong association with CAD. This study aimed to examine these associations in Southwest of Iran
Methods: Blood samples were collected from 200 CAD patients and 110 healthy individuals with no CAD. The association of two SNPs with CAD was evaluated by PCR and restriction fragment length polymorphism
Results: Chi-square test showed no association between rs1333040 SNP and CAD [X[2]: 4.66, df: 2, P=0.09]. Also, there was no association between rs1004638 SNP and CAD [X[2]: 0.27, df: 2, P=0.88]
Conclusion: No association was observed between rs1333040 and rs1004638 SNPs in the 9P21 region and CAD in Southwest of Iran
