摘要
Inherited defects in the gene encoding the methylnalonyl-CoA mutase (MCM) result in the mut forms of methylmalonic aciduria (MMA). Twelve mutations have been identified associated with the mut(-) phenotype. We report two novel mutations (R621N and D156N) in a compound heterozygote mut- patient. These two mutations and three previously published ones (H627N, A191E, Y231N) were mapped onto a three dimensional homology model of the human MCM constructed from the crystal structure of the Propionibacterium shermanii enzyme.
