Abstract

We report on a sib pair of Indian origin presenting with intellectual disability, dysmorphism, and macrocephaly. Exome sequencing revealed a homozygous splice site HERC1 mutation in both probands. Functional analysis revealed use of an alternate splice site resulting in formation of a downstream stop codon and nonsense mediated decay. In the LIGHT of recent reports of HERC1 mutations in two families with a similar phenotypic presentation, this report reiterates the pathogenic nature and clinical consequences of HERC1 disruption. © 2016 Wiley Periodicals, Inc.
