심근 경색
Myocardial infarction is more commonly known as a heart attack. It is the irreversible death of the heart muscle due to prolonged obstruction of blood supply to the organ. Case-controlled large scale studies utilizing Single Nucleotide Polymorphisms(SNPs) throughout the genome demonstrated that altered expression at 6 SNPs in the MIAT gene might confer genetic susceptibility to myocardial infarctions. MIAT has been demonstrated to encode a nonfunctional RNA. Although the exact function of MIAT is still unclear, knowledge of some of the genetic factors that contribute to the pathogenesis of myocardial infarction can lend itself to better diagnosis, prevention, and treatment. Despite all that has been discovered about MIAT, a causal link between MIAT and myocardial infarctions has not yet been demonstrated.
