Eight novel MUT loss-of-function missense mutations in Chinese patients with isolated methylmalonic academia.

Abstract excerpt

BACKGROUND: Isolated methylmalonic acidemia is a rare autosomal recessive metabolic disorder mostly caused by mutations in the methylmalonyl coenzyme A mutase (MCM) gene (MUT). This study aimed to verify whether missense mutations in MUT in Chinese patients affect the stability and enzymatic activity of MCM. METHODS: Eight Chinese patients were identified with novel mutations. Plasmids carrying the wild-type and...
