Two novel Warburg micro syndrome 1 cases caused by pathogenic variants in RAB3GAP1

Abstract

AbstractIn this study, we detected a novel pathogenic variant and a previously reported variant in RAB3GAP1 by whole-exome sequencing (NM_001172435.2: c.1552C>T, p.Gln518*; c.1471C>T, p.Arg491*). The first patient is a 3-year-old girl who presented with bilateral congenital cataracts, developmental delay, abnormal craniofacial features, drug-resistant constipation, and corpus callosum hypoplasia. The proband of the second family is a 13-year-old boy who suffers from developmental delay, quadriplegia, intellectual disability, abnormal craniofacial features, and corpus callosum hypoplasia.
