Genes affected

CHD1L (HGNC:1916): (chromodomain helicase DNA binding protein 1 like) This gene encodes a DNA helicase protein involved in DNA repair. The protein converts ATP to add poly(ADP-ribose) as it regulates chromatin relaxation following DNA damage. Overexpression of this gene has been linked to several types of cancers.
