Identification and analysis of gene mutations of an neurofibromatosis type 1 patient / 中国医师杂志

ABSTRACT

Objective To explore mutation diagnosis and discuss the pathogenic and clinical characteristics of neurofibromatosis type 1 (NF1).Methods DNA sequencing combined with denaturing highperformance liquid chromatography (DHPLC) method was used to diagnose patients and parents.Results A new nonsense mutations c.503C ＞ G(p.S168 *) was identified.Conclusions NF1 is a rare autosomal dominant genetic disease.Most of them are caused by new mutations.Genetic diagnosis of sporadic cases is very important for treatment and the future generations.
