3-methylglutaconic Aciduria With Cataracts, Neurologic Involvement, And Neutropenia; Megcann

Description

3-Methylglutaconic aciduria with cataracts, neurologic involvement, and neutropenia (MEGCANN) is an autosomal recessive inborn error of metabolism characterized primarily by increased levels of 3-methylglutaconic acid (3-MGA) associated with neurologic deterioration and neutropenia. The phenotype is highly variable: most patients have infantile onset of a progressive encephalopathy with various movement abnormalities and delayed psychomotor development, although rare patients with normal neurologic development have been reported. Other common, but variable, features include cataracts, seizures, and recurrent infections (summary by Wortmann et al., 2015 and Saunders et al., 2015).For a general phenotypic description and a discussion of genetic heterogeneity of 3-methylglutaconic aciduria, see MGCA1 (OMIM ).
