Within the last 25 years more than 400 cases with suspected Familial Glucocorticoid Deficiency (FGD) have been referred to our centre for genetic testing. All cases had low or undetectable serum cortisol paired with an elevated plasma ACTH level. Our patient cohort comprises 352 families from 30 different nationalities and ranges from neonates to patients in their eighties. In 1993 the first gene defect, in MC2R, was discovered by candidate gene sequencing. Subsequent...

Thyroid hormones play a major role in the metabolic function of mammalian cells and are of particular importance in the development of the fetal brain. The MCT8 gene has recently been shown to encode an active and specific thyroid hormone transporter. Recent reports have identified mutations in the MCT8 gene in several unrelated boys presenting with severe X-linked psychomotor retardation and elevated serum T3.Ontogeny of mRNA encoding MCT8 was examined ...
