What is the normal function of the CHD7 gene?
The CHD7 gene provides instructions for making a protein called chromodomain helicase DNA binding protein 7. The CHD7 protein belongs to a family of proteins that are thought to play a role in the organization of chromatin. Chromatin is the complex of DNA and protein that packages DNA into chromosomes. The CHD7 protein most likely regulates gene activity (expression) by a process known as chromatin remodeling. The structure of chromatin can be changed (remodeled) to alter how tightly DNA is packaged. When DNA is tightly packed, gene expression is lower than when DNA is loosely packed. Studies have shown that the CHD7 gene is expressed in many fetal tissues, including the eye, inner ear, and brain cells that process smell (olfactory bulb).
How are changes in the CHD7 gene related to health conditions?
