The present case control study performed in a homogeneous Caucasoid population confirms the Japanese results that T SNP of Cx37 gene is involved in AMI phenotype, demonstrating the consistency of the association across past studies and across different populations.
Recently, the C1019T polymorphism in the human gene encoding connexin 37 (CX37, encoded by GJA4) has been reported to be associated with coronary artery disease (CAD)/myocardial infarction in different racial groups, but no data are currently available in northern Han Chinese.
Recent large Japanese case-control studies identified connexin-37 (GJA-4), plasminogen activator inhibitor-1 (PAI-1), and stromelysin-1 (MMP-3) polymorphisms as risk factors for MI, but the prevalence of these genotypes among different racial groups in the U.S. needs to be determined.
Multiple epidemiological studies have associated a single nucleotide polymorphism (SNP) in the GJA4 gene, coding for connexin37 (Cx37), with increased risk for atherosclerosis and myocardial infarction.
Multiple epidemiological gene association studies have detected a link between a single nucleotide polymorphism in the human connexin37 (Cx37) gene and coronary artery disease or myocardial infarction in various populations.
Determination of the genotypes of the connexin 37, plasminogen-activator inhibitor type 1, and stromelysin-1 genes may prove reliable in predicting the genetic risk of myocardial infarction and might thus contribute to the primary prevention of this condition.
