Deskripsi

Glutaric aciduria type 1 is a rare autosomal recessive disorder caused by a deficiency of glutaryl-CoA dehydrogenase, which is the key mitochondrial enzyme involved in the final degradation of lysine, L-hydroxylysine, and L-tryptophan. It is an inherited organic acidemia characterized by macrocephaly and dystonia, which results in high morbidity and mortality. In resource-limited countries like Nepal, where enzyme assays are not available, MRI has a great role to play in supporting diagnosis in such situations. Here, we present 2 cases of glutaric aciduria type 1 in brothers from the same parent that were diagnosed by MRI, and subsequent diet modification and L-carnitine therapy led to improvement of clinical symptoms.
