Background-Aim: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders caused by defects in the steroidogenic pathway of the adrenal cortex. In their most severe forms, they produce adrenal insufficiency and virilization of external genitalia when involving the terminal enzymes of the cortisol and aldosterone synthesis pathway (21-hydroxylase (21-OHD, OMIM#201910) and 11-hydroxylase (11-OHD, OMIM#202010) deficiencies). Mutations of <e...

Background: Congenital hypopituitarism (CH) is a group of disorders characterized by deficiencies in one or more hypophyseal hormones and a marked variability in genotype-phenotype correlations. Central diabetes insipidus (DI) is caused by a decreased release of ADH and results in a variable degree of polyuria. Their association is normally found in congenital cerebral midline abnormalities, such as septo-optic dysplasia.Objectiv...

Background: GL1I2 encodes a zinc-finger transcription factor expressed in the developing hypothalamus and in Rathke's pouch, the embryonic precursor of the pituitary gland. Pathogenic GL1I2 variants have been implicated in the etiology of the broad clinical spectrum of congenital hypopituitarism (CHY): holoprosencephaly, midline facial abnormalities, Culler-Jones syndrome, combined pituitary hormone-deficiency (CPHD) and isolated GH-defi...
