A mutation in the hepatocyte nuclear factor-4 alpha (HNF-4 alpha) gene has been recently reported to cause maturity-onset diabetes of the young (MODY) (Yamagata, Furuta, et al., 1996). The mutation can also be a good candidate for the responsible gene of non-insulin dependent diabetes mellitus (NIDDM). The existence of the mutated allele of Q268X (C to T substitution within the exon 7 of HNF-4 alpha gene) was searched in 514 alleles of Japanese NIDDM patients by polymerase chain reaction-restriction fragment length polymorphism analysis. No mutation was found in these patients. The result showed that the Q268X mutation of HNF-4 alpha gene was not frequent among general NIDDM patients and that it cannot serve as the major diabetogenic gene in the Japanese ethnic group.
最近有报道称,肝细胞核因子-4α(HNF-4α)基因的突变会导致青年发病的成年型糖尿病(MODY)(山形、古田等人,1996年)。该突变也可能是2型糖尿病(NIDDM)致病基因的有力候选者。通过聚合酶链反应-限制性片段长度多态性分析,在514个日本2型糖尿病患者的等位基因中搜索了Q268X突变等位基因(HNF-4α基因第7外显子内的C到T替换)。在这些患者中未发现突变。结果表明,HNF-4α基因的Q268X突变在普通2型糖尿病患者中并不常见,且在日本人群中它不能作为主要的致糖尿病基因。
