Prenatal diagnosis of Weyers syndrome (deficient ulnar and fibular rays with bilateral hydronephrosis)

Abstract

A fetus with Weyers oligodactyly was studied after a previous sibling had been born with that condition. Prenatal diagnosis was undertaken using ultrasound to visualize the long bones, which were found to be severely affected by the condition at 19 weeks of gestation. Most notable were the ulnae and fibulae, which were very short; the fetus had bilateral hydronephrosis.
