gene deletion in an Indian boy with adrenal hypoplasia congenita.
At the gene level, mutations in the SRY, SOX9, DMRT1 and DAX1
genes have been reported as causes of ovotesticular DSD (3,4,5,7).

knockout in the monkey recapitulates human AHC-HH," Human Molecular Genetics, vol.
Nanog also interacts with transcriptional regulators such as Oct4, DAX1
, NAC1, ZFP281, and SALL4 , thereby forming through them a link with a number of other regulatory proteins, including the proteins of the Polycomb group .
Chronic perturbations in glucose metabolism and hyperinsulinemia have been shown to impair the Leydig cell steroidogenesis via insulin-mediated induction of DAX1
(dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1), thus causing testosterone deficiency in mice .
Most common is DAX1
deficiency which is due to genetic defects in NR0B1, located on chromosome Xp21.2.
AHC manifests itself mainly in early infancy or in childhood and is caused by deletions or point mutations in the NR0B1 (DAX1
) (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1) gene (OMIM*300473) (Figures 1(a)-1(c)) .
SRY, SOX9 and DAX1
expression patterns during human sex determination and gonadal development.
Genes frequently involved in complex GKD include DMD, variations in which cause Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD), and NR0B1 (DAX1
), which is responsible for adrenal hypoplasia congenita (AHC) (2, 3).
El desarrollo de las crestas obedece a la accion de un grupo de genes como WT1, SF1, DAX1
, Lim1, EMX2, LHX9, situados en cromosomas autosomicos (1).
