We report on a family where the propositus had G syndrome, including laryngeal cleft, and another relative had the facial anomalies typical of the BBB syndrome. We review the literature on the BBB and G syndrome, and argue that no clinical or laboratory criteria permit a differential diagnosis of the two syndromes. Therefore, we suggest that they should be considered variable expression of the same gene. The name BBBG syndrome is proposed for the amalgamated syndrome.
