A novel EFNB1 mutation (c.712delG) in a family with craniofrontonasal syndrome and diaphragmatic hernia

Am J Med Genet A. 2010 Oct;152A(10):2574-7. doi: 10.1002/ajmg.a.33596.

Abstract

We report on the occurrence of congenital diaphragmatic hernia in a family with craniofrontonasal syndrome found to have a previously unreported mutation in EFNB1. The female proband presented with hypertelorism, telecanthus, bifid nasal tip, widow's peak, frontal bossing, and a widened metopic suture. Her father was noted to have hypertelorism, telecanthus, widow's peak, and a history of pectus carinatum. He was found to have a previously unreported mutation in exon 5 of EFNB1 predicted to cause premature protein truncation. The parents of the proband previously had a female fetus with congenital diaphragmatic hernia. The occurrence of congenital diaphragmatic hernia, phenotypic differences between males and females, and utility of molecular testing in craniofrontonasal syndrome are demonstrated.
