Abstract

BCORL1, a transcriptional corepressor, is involved in negative gene regulation through associations with several protein complexes including Class II histone deacetylases (HDACs). Acquired somatic mutations in BCORL1 have been implicated in the pathogenesis of several malignancies, but germline mutations of BCORL1 have not been associated with a specific genetic syndrome. We report five individuals from three pedigrees with phenotypes including intellectual disability, behavioral difficulties, and dysmorphic features who were found via whole exome sequencing to have variants in BCORL1. In silico analysis of these variants strongly suggests pathogenicity. We propose that hemizygous pathogenic variants in BCORL1 underlie a newly identified X-linked epigenetic syndrome.
