X‐LINKED CONGENITAL ADRENAL HYPOPLASIA A Study of Five Generations of a Greenlandic Family

. In a Greenlandic family comprising 171 descendants in 5 generations, 11 boys had died with a clinical picture of adrenocortical insufficiency within three weeks of birth. Three treated male patients, who survived, were closely studied. The adrenal glands could not be identified by computed tomography. The clinical picture and biochemical studies were consistent with congenital adrenal hypoplasia. The pedigree indicates X-linked recessive inheritance. The pubertal development was delayed in two patients aged 14 years. LHRH stimulation yielded a significant rise in LH and FSH in at least one of the patients, adrenal androgen values were very low. A family instruction programme has been set up.
