A pair of sisters was ascertained for multiple congenital defects, including marked craniofacial dysmorphisms with blepharophimosis, and severe psychomotor delay. Two novel compound heterozygous mutations in UBE3B were identified in both the sisters by exome sequencing. These mutations include c.1A>G, which predicts p.Met1?, and a c.1773delC variant, predicted to cause a frameshift at p.Phe591fs. UBE3B encodes a widely expressed protein ubiquitin ligase E3B, which, when mutated in both alleles, causes Kaufman oculocerebrofacial syndrome. We report on the thorough clinical examination of the patients and review the state of art knowledge of this disorder. (c) 2015 Wiley Periodicals, Inc.
