We report on two male sibs, a fetus and a newborn, with short humeri and dysmorphic facial features including blepharophimosis. The newborn also had Hirschsprung disease. Goldberg-Shprintzen syndrome and the Say-Barber-Biesecker-Young-Simpson type of Ohdo syndrome were suspected but direct sequencing of KBP and KAT6B failed to identify a mutation. Finally, direct sequencing of MED12, the gene mutated in Opitz-Kaveggia syndrome, Lujan-Fryns syndrome and X-linked Ohdo syndrome identified in the two sibs the missense mutation c.3443G>A (p.Arg1148His) inherited from the mother. This report further expands the phenotypic spectrum of MED12 mutations.
