摘要

在日本,与MELAS(线粒体肌病、脑病、乳酸性酸中毒和卒中发作)相关的第二常见突变是3271突变。在一个葡萄牙和意大利血统的巴西家庭中发现了这种突变,这表明这种突变也存在于除日本人以外的种族中。该患者有轻度的非典型MELAS临床表现,提示3271突变患者表现出与3243突变相同的异质性表型表达。

A Caucasian Family with the 3271 Mutation in Mitochondrial DNA

The second most common mutation associated with MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-hire episodes) in Japan is the 3271 mutation. This mutation was found in a Brazilian family of Portuguese and Italian descent, indicating that this mutation also exists in a race other than Japanese. The propositus had mild clinical manifestations atypical of MELAS, suggesting that patients with the 3271 mutation exhibit heterogeneous phenotypic expression as seen in the 3243 mutation.
