PROBLEM TO BE SOLVED: To provide a method by which genetic polymorphism [single nucleotide polymorphism (SNP)] associated with myocardial infarction is identified and inflammatory diseases, including the myocardial infarction are judged by utilizing the genetic polymorphism.SOLUTION: The method for judging the inflammatory diseases comprises detecting at least one kind of polymorphism in six SNPs present in a new gene MIAT (myocardial infarction associated transcript) having a specific base sequence and considered to encode an mRNA-like noncoded RNA. Furthermore, an oligonucleotide usable in the method and a kit for diagnosing the inflammatory diseases are provided.COPYRIGHT: (C)2008,JPO&INPIT【課題】心筋梗塞と関連性のある遺伝子多型(SNP)を同定し、その遺伝子多型を利用して心筋梗塞をはじめとする炎症性疾患を判定する方法を提供する。【解決手段】特定の塩基配列を有し、mRNA様の非コードRNAをコードすると考えられる新規遺伝子MIAT内に存在する6個のSNPの中少なくとも一種の多型を検出することを含む、炎症性疾患の判定方法。及び、該方法に用いることのできるオリゴヌクレオチド、炎症性疾患診断用キット。【選択図】なし
