Green List (high evidence)

Biallelic STAR variants cause lipoid adrenal hyperplasia, XY males are born with female external genitalia.

PMID: 8948562: Out of the 15 participants from this study, nine 46, XY karyotype individuals with biallelic STAR variants, had phenotypically normal female genitalia. 46,XX karyotype with biallelic STAR variants have phenotypic female genitalia.

PMID: 16968793. Three patients reported with homozygous STAR variants and lipoid adrenal hyperplasia. However, 46,XY brothers from a consanguineous family, were born after uneventful pregnancies and had normal male genitalia with descended testes.

Red List (low evidence)

Postnatal onset

Lipoid congenital adrenal hyperplasia, the most severe disorder of steroid hormone biosynthesis, is caused by a defect in the conversion of cholesterol to pregnenolone, the first step in adrenal and gonadal steroidogenesis. All affected individuals are phenotypic females with a severe salt-losing syndrome that is fatal if not treated in early infancy.

Multiple individuals reported plus mouse studies (PMID 9326645)
