title: Congenital adrenal hyperplasia I. Family studies of IQ.
abstract: Thirty-one patients diagnosed as having congenital adrenal hyperplasia were given standardized IQ tests.  Patients' IQ was found not to be significantly higher than the IQ of nonaffected siblings or the expected IQ from parental values.  Thus the adrenogenital syndrome appears to confer no IQ advantage independent of family IQ level.
