[From gene to disease; congenital adrenal hypoplasia and the DAX-1 gene].
Congenital adrenal hypoplasia is an X-linked disorder resulting in adrenocortical deficiency, failure to complete puberty due to hypogonadotrophic hypogonadism, and infertility. The disease is caused by mutations in the DAX-1 gene. The DAX-1 protein is a transcription inhibitor; it represses the transcription of other, as yet mostly unknown, genes. Mutation analysis can confirm a clinical diagnosis of congenital adrenal hypoplasia. An early diagnosis might prevent critical damage due to an adrenal crisis in an undiagnosed patient. Molecular testing can be used for carrier detection and genetic counselling.
