Familial glucocorticoid deficiency associated with point mutation in the adrenocorticotropin receptor.

Journal article

Familial glucocorticoid deficiency is an uncommon disorder that appears to be due to congenital insensitivity or resistance to adrenocorticotropin (ACTH), and is usually inherited in an autosomal recessive pattern. We investigated the DNA base sequence in a family with this condition by polymerase chain reaction amplification of DNA with pairs of primers that span the ACTH-receptor domain. The affected male proband showed a single base mutation, ser74-->ile, in the sequence coding for the second transmembrane domain of the ACTH receptor. A similar defect was found in an affected sister, a normal sequence in an unaffected brother, and both alleles in each parent. This is only the second clinical disorder associated with a GTP-binding-protein-linked hormone-receptor mutation.
