Chromosomal microdeletions and duplications are one of the major causes of congenital malformations and developmental delay.Lately by the effect of array-CGH,many new syndromes are defined in patients with congenital malformations and developmental delay.Xp21 contiguous gene deletion syndrome is one of the rare microdeletion syndromes.This syndrome is characterized by developmental delay,congenital adrenal hypoplasia, DuchenneMuscularDystrophy (DMD) and glycerol kinase deficiency.
