實體腫瘤檢測MSH2基因介紹
該基因座在遺傳性非息肉性結腸癌（HNPCC）中經常發生突變。克隆時，發現它是大腸桿菌錯配修復基因muts的人類同源物，與在hnpcc中發現的微衛星序列（rer+表型）的特征性變化一致。兩個編碼不同亞型的轉錄變體已經被發現。
This locus is frequently mutated in hereditary nonpolyposis colon cancer (HNPCC). When cloned, it was discovered to be a human homolog of the E. coli mismatch repair gene mutS, consistent with the characteristic alterations in microsatellite sequences (RER+ phenotype) found in HNPCC. Two transcript variants encoding different isoforms have been found for this gene.
