Prenatal diagnosis of congenital dysgranulopoietic neutropenia

Summary. Congenital dysgranulopoietic neutropenia is a severe life-threatening disease characterized by specific dysmorphic granulocytes. Prenatal diagnosis of congenital neutropenia was reported first in 1983. In 1989 we reported a family with congenital dysgranulopoietic neutropenia in two siblings (one male and one female): in 1992 the mother became pregnant and prenatal diagnosis was performed by cordocentesis. The results we obtained from the fetus at risk enabled us to suggest that it was not affected, and we advised the parents that the pregnancy could continue: a healthy female was born. The neutrophil count at 2 and 4 months was normal.
