Abstract excerpt
Isolated methylmalonic aciduria (MMA) is an autosomal-recessive disorder of propionate metabolism that is most commonly caused by mutations in the methylmalonyl-CoA mutase (MUT) gene (mut-type MMA). We investigated a cohort of 151 patients, classifying 114 patients as mut(0) and 32 as mut(-) (five not defined). As per the definition, mut(-) patients showed a higher propionate incorporation ratio in vitro, which...
