22q11.21 Copy Number Variation

Description

The 22q11.2 copy number variation syndrome can result in the loss or duplication of up to 46 protein-coding genes, which have wide-spread effects on human development. In case of deletion, the loss of TBX1 is thought to be responsible for a large proportion of the 22q11.2DS phenotype, due its role in the development of the heart, thymus, thyroid, parathyroids and more.
