Joubert syndrome associated with Leber amaurosis and multicystic kidneys.

We describe a boy with manifestations of Joubert syndrome, Leber congenital amaurosis, and multicystic kidneys. In infants with unexplained neonatal tachypnea and late developmental delay, absence or hypoplasia of the cerebellar vermis should be sought. Joubert syndrome probably is an autosomal recessive disorder. In the subsequent pregnancy of the propositus' mother, we were able to make a prenatal diagnosis of Joubert syndrome, one of the first to be reported. © 1993 Wiley-Liss, Inc.
