Homozygous and heterozygous retinal phenotypes in families harbouring IMPG2 mutations

Abstract excerpt

Introduction: Biallelic mutations in interphotoreceptor matrix proteoglycan 2 (IMPG2) have been shown to underlie recessive childhood-onset rod-cone dystrophy with early macular involvement in several families. In other families, heterozygous IMPG2 mutations have been associated with dominant vitelliform macular dystrophy. To date, the retinal phenotype of heterozygotes from families with recessive IMPG2-related...
