Short stature homeobox gene or SHOX is a gene on the X and Y chromosomes . Mutations in SHOX or the presence of only one copy in the genome ( haploinsufficiency ) are associated with short stature in humans .
function
The SHOX gene is a homeobox gene. These are genes that are important for the organization of the body in embryonic development . The SHOX gene consists of 6 different exons and is located in the pseudoautosomal region (PAR1) of the X and Y chromosomes. Homologous genes have been found in different animals.
pathology
This gene was discovered during research into the genetics of Turner syndrome . In this disease there is a loss of genetic material from the X chromosome, typically due to a lack of the entire X chromosome.
After its discovery, it was found that SHOX also plays a role in other diseases that are associated with short stature. These are above all Léri Weill's dyschondrosteosis and Langer's mesomelic dysplasia .
Gene dose effects of additional SHOX copies may play a role in the development of tall stature in other aneuploidies of the sex chromosomes such as triplo-X syndrome , XYY syndrome , Klinefelter syndrome , 48, XXYY syndrome, etc.
