What is the official name of the CHD1L gene?

The official name of this gene is “chromodomain helicase DNA binding protein 1-like.”

CHD1L is the gene's official symbol. The CHD1L gene is also known by other names, listed below.

Read more about gene names and symbols on the About page.

What is the normal function of the CHD1L gene?

From NCBI GeneThis link leads to a site outside Genetics Home Reference.:

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. Several alternatively spliced transcripts variants have been described for this gene. [provided by RefSeq, Jan 2012]

From UniProtThis link leads to a site outside Genetics Home Reference.:

DNA helicase which plays a role in chromatin-remodeling following DNA damage. Targeted to sites of DNA damage through interaction with poly(ADP-ribose) and functions to regulate chromatin during DNA repair. Able to catalyze nucleosome sliding in an ATP-dependent manner. Helicase activity is strongly stimulated upon poly(ADP-ribose)-binding.

How are changes in the CHD1L gene related to health conditions?

Genetics Home Reference provides information about 1q21.1 microdeletion, which is associated with changes in the CHD1L gene.
UniProt and NCBI Gene cite these articles in OMIM, a catalog designed for genetics professionals and researchers that provides detailed information about genetic conditions and genes.
