A Novel Disease-Causing ASPA Gene Mutation (c.432+1 G>C) in an Iranian Patient with Canavan Disease: A Case Report

Abstract

Canavan disease is an autosomal recessive genetic disease and rare fatal childhood neurological disorder caused by mutations in the ASPA gene, which resulted in a catalytic deficiency of the ASPA enzyme that catalyzes the hydrolysis of NAA into aspartate and acetate. Herein, we report an Iranian patient diagnosed with Canavan disease with a novel splice-site mutation in the ASPA gene (NM_000049.4; c.432+1 G>C). This report is based on a homozygous c.432+1 G>C mutation in the ASPA gene identified from an Iranian patient. As a result, a novel homozygous pathogenic mutation on ASPA is the cause of disease in the patient.
