Usefulness of a registry of congenital malformations for genetic counseling and prenatal diagnosis.
During three years, 39,924 infants born consecutively in the area covered by our registry of congenital malformations were surveyed; 775 had major congenital malformations. Recurrence risks for the major malformation was estimated and classified as high (greater than 10%, 5.3% of the cases), low (1 to 10%, 85.3% of the cases) or occasional (less than 1%, 9.4% of the malformed). Feasibility of prenatal diagnosis was considered. On the basis of the recurrence risk of 1% or higher and the feasibility of prenatal diagnosis, such a procedure should be considered in future pregnancies in 64.1% of the mothers. Genetic counseling has to be given to couples at risk of having a malformed child. For this purpose, as is shown in our study, the best way is the possibility of using a registry of congenital malformations.
