Autosomal recessive tetralogy of Fallot, unusual facies, communicating hydrocephalus, and delayed language development: a new syndrome?
We report a pattern of malformation affecting five of seven siblings born to unaffected Afghani parents who are first cousins. Their first two children died during infancy of cyanotic congenital heart defects. Two living male siblings have tetralogy of Fallot, developmental delay principally affecting language skills, and short palpebral fissures or midfacial hypoplasia. Another male has communicating hydrocephalus and hypertelorism. The striking number of siblings with tetralogy of Fallot, or another cyanotic congenital heart defect, and the parental consanguinity, suggests autosomal recessive inheritance in this family. While several other families have been identified with apparent recessive inheritance of tetralogy of Fallot, the associated malformations in our family suggest a unique, and previously unreported, malformation pattern.
