We report a family in which Opitz-Frias G syndrome is expressed across 4 generations. The propositus displays hypertelorism, low grade hypospadias, cleft palate and lips and cleft larynx, making the diagnosis of G syndrome very likely. A cousin of his mother discloses similar clefts, vulviform hypospadias, anal imperforation and mental retardation. His clinical appearance fits perfectly the diagnosis of BBB syndrome. A nephew shows ambiguous genitalia and hypertelorism. Authors suggest the lumping of the BBB and the G syndrome.
