[Hypertelorism-hypospadias (BBB) syndrome. 2 additional family studies].

We report on two unrelated families with the hypertelorism-hypospadias (BBB-) syndrome. The male index patients, 3 and 10 months old, respectively, have ocular hypertelorism, cleft lip and palate, high and broad nasal bridge and hypospadias. The patients' mothers, maternal grandmothers and one patient's sister show hypertelorism.

Morquio syndrome (mucopolysaccharidosis IV B) associated with beta-galactosidase deficiency. Report of two cases.

Two male patients, aged 6 and 25, both with normal intelligence and absence of neurological abnormalities, exhibited dysostosis multiplex, dwarfism, odontoid anomalies, cloudy corneas, exessive excretion of keratan sulfate, and abnormal urinary oligosaccharides. Leukocytes and fibroblasts of both patients were deficient in acid beta-galactosidase (beta-gal) and normal in N-acetylgalactosamine-6-sulfate sulfatase, the deficient enzyme in classical Morquio syndrome. The beta-gal deficiency was not due to an endogenous inhibitor, and the parents exhibited intermediate activities.
