Multiple pituitary hormone deficiencies in eight siblings of one Jewish Moroccan family.

In a Jewish Moroccan inbred family, 8 of 12 siblings were found to have multiple deficiencies of pituitary hormones, including GH, TSH and gonadotrophins. The parents showed no deficiency and are in good health, as are the other 4 siblings. The investigations carried out indicate that in this family the etiology is hereditary in nature, probably being autosomal recessive, with the defect located in the pituitary gland.
