The parents of a neonate with adrenogenital hyperplasia tell the nurse that they are afraid to have any more children. The nurse should explain which statement about adrenogenital hyperplasia?

A) It is not hereditary.
B) Genetic counseling is indicated.
C) It can be prevented during pregnancy.
D) All future children will have the disorder.

Some forms of adrenogenital hyperplasia are hereditary and should be referred for genetic counseling. Affected offspring should also be referred for genetic counseling. There is an autosomal recessive form of adrenogenital hyperplasia. A prenatal treatment with glucocorticoids can be offered to the mother during pregnancy to avoid the sex ambiguity, but it does not affect the presence of the disease. If it is the heritable form, for each pregnancy, a 25% risk occurs that the child will be affected.
