title: Prenatal findings in trisomy 16q of paternal origin.
abstract: A 34-year-old pregnant woman was referred at 30 weeks of gestation with suspected fetal congenital heart disease. On prenatal ultrasound the following anomalies were detected: intra-uterine growth retardation, micrognathia, coarctation of the aorta with ventricular and atrial septal defects, ambiguous external genitalia, and clinodactyly of one hand with adducted thumb. Prenatal karyotyping was offered but refused by the patient. The fetus was delivered by Caesarean section due to fetal distress at 36 weeks of gestation. The neonate, weighing 2150 g was transferred to the neonatal intensive care unit, where he died 10 days later. The karyotype from peripheral blood lymphocytes was 46,XY+der(20)t(16;20)(q12.1;p13)pat. The maternal karyotype was unremarkable, whereas the father had the translocation t(16;20)(q12.1;p13). Necropsy confirmed all the prenatal findings. These are discussed together with the implications of the chromosomal diagnosis and the pertinent literature is reviewed.
