A novel compound heterozygous IBA57 mutation is presented in a boy with severe global developmental delay, optic atrophy, spastic paraplegia, and focal epileptic seizures.

Abstract

Pathogenic variants of IBA57 (OMIM ID: 615330) are usually associated with multiple mitochondrial dysfunction syndrome (MMDS) and hereditary spastic paraplegia type 74 (SPG74). Here, we present a novel compound heterozygous IBA57 mutation in a boy with severe global developmental delay, optic atrophy, spastic paraplegia, and focal epileptic seizures.
