Deficiency of 2-methylbutyryl-CoA dehydrogenase

2-Methylbutyryl-CoA dehydrogenase deficiency is an autosomal recessive metabolic disorder of impaired isoleucine degradation. It is most often ascertained via newborn screening and is usually clinically asymptomatic, although some patients have been reported to have delayed development and neurologic signs. Therefore, the clinical relevance of the deficiency is unclear (Sass et al., 2008).
