What is the official name of the BRIP1 gene?
The official name of this gene is “BRCA1 interacting protein C-terminal helicase 1.”
BRIP1 is the gene's official symbol. The BRIP1 gene is also known by other names, listed below.

What is the normal function of the BRIP1 gene?
The BRIP1 gene provides instructions for making a protein that is involved in repairing damaged DNA. Within the nucleus of cells, the BRIP1 protein interacts with the protein produced from the BRCA1 gene. These two proteins work together to mend broken strands of DNA, which prevents cells from accumulating genetic damage that can trigger them to divide uncontrollably. Because BRIP1 and BRCA1 help control the rate of cell growth and division, these proteins are described as tumor suppressors.
DNA is arranged in two long strands that form a spiral called a double helix. The BRIP1 protein acts as a helicase, which means that it attaches to particular regions of DNA and temporarily separates the two strands. By unwinding the strands near sites of DNA damage, the BRIP1 protein allows other proteins (such as BRCA1) to reach damaged areas and fix them. Breaks in DNA can be caused by natural and medical radiation or other environmental exposures, and also occur when chromosomes exchange genetic material in preparation for cell division. By helping repair mistakes in DNA, the BRIP1 protein plays a role in maintaining the stability of a cell's genetic information.
Does the BRIP1 gene share characteristics with other genes?
The BRIP1 gene belongs to a family of genes called FANC (Fanconi anemia, complementation groups).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
How are changes in the BRIP1 gene related to health conditions?
Genetics Home Reference provides information about Fanconi anemia, which is also associated with changes in the BRIP1 gene.
Where is the BRIP1 gene located?
Cytogenetic Location: 17q22.2
Molecular Location on chromosome 17: base pairs 61,679,185 to 61,863,558
The BRIP1 gene is located on the long (q) arm of chromosome 17 at position 22.2.
More precisely, the BRIP1 gene is located from base pair 61,679,185 to base pair 61,863,558 on chromosome 17.
