The fetal valproate syndrome (FVS) is characterized by distinctive facial appearance, major and minor malformations, and developmental delay. Generally, only a small proportion of prenatally exposed children are affected. The authors describe three families in whom the occurrence of FVS in all the siblings strongly suggests hereditary susceptibility to valproic acid-induced adverse outcome. The risk for recurrence in a subsequent pregnancy may be high and should be taken into account in the counseling of parents and in considering drug treatment.
