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.

The c.226G>T (p.G76W) alteration is located in exon 2 (coding exon 2) of the CHD1L gene. This alteration results from a G to T substitution at nucleotide position 226, causing the glycine (G) at amino acid position 76 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
