title: First report of management and outcome of pregnancies associated with hereditary orotic aciduria.
abstract: Two pregnancies in a 25-year-old woman with hereditary orotic aciduria who was managed prenatally on uridine therapy are described. The first pregnancy resulted in an infant with multiple congenital anomalies and a 47,xx,inv(4)(p12q25), +der(22)t(11;22)(p23;q11) karyotype. The proposita was found to be a carrier of a de novo 11;22 translocation and a pericentric inversion of chromosome 4. Subsequently, several carriers of orotic aciduria in this family were identified with the inverted chromosome 4. The second pregnancy resulted in a normal male with an inverted chromosome 4.
