47,XYY males are found in approximately 1 per 1,000 men. There is no significant difference in intelligence compared with a normal karyotype group. 47,XYY males are fertile and are considered to be relatively tall in stature owing to the increased growth velocity during the earliest childhood. It has been known that 47,XYY males are usually quite normally developed at birth with normal birth weight and length without any physical abnormalities. We have experienced a case of 47,XYY male with increased nuchal fold thickness, choroid plexus cyst and limb anomaly and we report the case with brief review of the literature. A 31-year-old woman, who had terminated her first pregnancy due to limb anomaly at 24 weeks gestation, received ultrasonography at about 16 weeks gestation and was found having a fetus with increased nuchal fold, choroid plexus cyst and limb anomaly. Through the genetic counselling, her pregnancy was terminated and the chromosome karyotyping was performed with the fetal tissue and parent's peripheral blood. The results revealed that the parents had normal karyotypes, but the karyotype of the fetus showed 47,XYY.
Key Words: 47,XYY, Limb anomaly, Choroid plexus cyst, Increased nuchal fold thickness
