Familial mental retardation associated with balanced chromosome rearrangement rcp t(8;11)(q24.3;p15.1).

abstract：:Adrenal hypoplasia congenita (AHC) can occur due to deletions or mutations in the DAX 1 (NR0B1) gene on the X chromosome (OMIM 300200). This form of AHC is therefore predominantly seen in boys. Deletion of the DAX 1 gene can also be part of a larger contiguous deletion including the centromeric dystrophin and glycerol...

In view of the low reproductive fitness of affected males, the high incidence of the syndrome has been suggested to be the result of a high rate of new mutations occurring exclusively in the male germline.
