Background: The Xp21 contiguous gen deletion syndrome is a rare disorder which is characterized by complex glycerol kinase deficiency, congenital adrenal hypoplasia, intellectual disability and Duchenne muscular dystrophy. It is caused by partial deletion of Xp 21. On Xp21 several genes are located contiguously, such as NR0B1/DAX1, dystrofin gen and gene for glycerol kinase, and the clinical features depend on the size of the deletion. The major clinical manif...

Background: Deletions of distal chromosome 9p24 are often associated with 46,XY gonadal dysgenesis and, depending on the extent of the deletion, the monosomy 9p syndrome. The phenotype shows variable expressivity and is related to the size of the deletion. XY sex reversal is a relatively rare type of DSD (disorder of sexual development). Terminal region of short arm chromosome 9p (9p24.3 region) contains 3 types of DMRT genes (DMRT1-3). DMRT1 gen acts in syner...
