What is the official name of the RECQL4 gene?
The official name of this gene is “RecQ helicase-like 4.”
RECQL4 is the gene's official symbol. The RECQL4 gene is also known by other names, listed below.

What is the normal function of the RECQL4 gene?
The RECQL4 gene provides instructions for making one member of a protein family called RecQ helicases. Helicases are enzymes that bind to DNA and temporarily unwind the two spiral strands (double helix) of the DNA molecule. This unwinding is necessary for copying (replicating) DNA in preparation for cell division, and for repairing damaged DNA. Because RecQ helicases maintain the structure and integrity of DNA, they are known as the "caretakers of the genome."
The RECQL4 protein is active in several types of cells before and after birth. Researchers believe that this protein is particularly important in cells of the developing bones and skin. It has also been found in enterocytes, which are cells that line the intestine and absorb nutrients.
How are changes in the RECQL4 gene related to health conditions?
Where is the RECQL4 gene located?
