Delayed-onset adrenal hypoplasia congenita and hypogonadotropic hypogonadism caused by a novel mutation in DAX1

In this study, we described a male who presented with delayed-onset adrenal hypoplasia congenita (AHC) and mild hypogonadotropic hypogonadism (HHG) without a relevant family history. A novel mutation in the DAX1 (dosage-sensitive sex reversal, congenital adrenal hypoplasia critical region on the X chromosome, gene 1) gene was shown to cause X-linked AHC and HHG. Genetic analysis revealed a novel nonsense mutation, c.154G > T (p.Glu52Term), in...
