Congenital hyperplasia of the adrenal cortex is manifested in boys as macrogenitosomia praecox and in girls as female pseudohermaphroditism, with or without concomitant adrenocortical insufficiency.
Some tendency to familial occurrence of congenital adrenocortical hyperplasia has previously been observed. According to a survey by Bentinck et al. (1952) a total of 97 cases of familial somatosexual aberrations affecting 42 families were reported between 1852 and 1952. Eighty of these children were either definitely or probably female pseudohermaphrodites and 17 had either demonstrable or probable macrogenitosomia praecox. In no family, however. was it possible to demonstrate virilizing adrenocortical hyperplasia in more than one generation. Wilkins et al. (1950, 1955) have accordingly assumed that congenital hyperplasia of the adrenal cortex is due to a recessive hereditary genital defect, clinically manifest only in homozygotes.
In this paper a description will be given of the clinical findings in a family with six children, including three
