Autosomal dominant iridogoniodysgenesis with associated somatic anomalies: four-generation family with Rieger's syndrome

A family extending over 4 generations showed iridogoniodysgenesis accompanied by somatic malformations inherited in an autosomal dominant fashion. Iridogoniodysgenesis was present in 10 members, of whom 5 had established glaucoma; 4 youthful members are likely to develop glaucoma. Somatic malformations were present in 5 members from the 3rd and 4th generations who did not manifest iridogoniodysgenesis. A possible polygenic basis is discussed, though the variable expression of an autosomal dominant inheritance is still the more likely explanation.
