Association between peroxisomal biogenesis factor 7 and autism spectrum disorders in a Korean population.

Abstract

Autism spectrum disorder is a neurodevelopmental disorder characterized by deficits in social communication, impaired reciprocal social interaction, and repetitive patterns of behaviors or interests. Although the cause of autism spectrum disorder remains elusive, the present study identified peroxisomal biogenesis factor 7 (PEX7) as a gene associated with autism spectrum disorder, and this association was examined in a Korean population. PEX7 encodes a cytosolic receptor for peroxisome targeting signal 2 of peroxisomal matrix enzymes that are targeted to and translocated into the peroxisome. PEX7 defects are associated with rhizomelic chondrodysplasia punctata type 1 and Refsum disease. Mutations in PEX7 are related to a variety of mild to severe clinical symptoms, including mental retardation. The analysis of 9 intronic single nucleotide polymorphisms in 214 patients with autism spectrum disorder and 258 controls revealed the association of 2 single nucleotide polymorphisms and 1 haplotype with autism spectrum disorder (P < .05).
