Consecutive successful pregnancies of a patient with nail-patella syndrome

Nail-patella syndrome is a genetic disorder with some characteristic features (nail dysplasia, patellar hypoplasia, elbow dysplasia, iliac horns and renal symptoms). Renal involvement of these patients requires close follow-up in pregnancy to avoid complications like preeclampsia. In this report, we have presented two consecutive successful pregnancies of a patient with nail-patella syndrome. The first pregnancy resulted with a newborn with nail-patella syndrome and the second pregnancy resulted in a healthy newborn without any obstetric complications. Renal functions were closely followed-up during both pregnancies, and basal renal functions were normal in the pregestational period, which seems to be the most important predictor of obstetric hypertensive complications. Prenatal diagnosis of nail-patella disease is also challenging due to several possible mutations and a wide range of phenotypes of the disease. Ultrasonographic examination findings may be suspicious for the disease in the fetus like patellar hypoplasia or joint contractures.
