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?

From NCBI Gene (

The protein encoded by this gene is a member of the RecQ DEAH helicase family and interacts with the BRCT repeats of breast cancer, type 1 (BRCA1). The bound complex is important in the normal double-strand break repair function of breast cancer, type 1 (BRCA1). This gene may be a target of germline cancer-inducing mutations. [provided by RefSeq, Jul 2008]

From UniProt (FANCJ_HUMAN) (

DNA-dependent ATPase and 5' to 3' DNA helicase required for the maintenance of chromosomal stability. Acts late in the Fanconi anemia pathway, after FANCD2 ubiquitination. Involved in the repair of DNA double-strand breaks by homologous recombination in a manner that depends on its association with BRCA1.

How are changes in the BRIP1 gene related to health conditions?

Genetics Home Reference provides information about these conditions associated with changes in the BRIP1 gene:
  • breast cancer
  • Fanconi anemia
  • ovarian cancer
UniProt (FANCJ_HUMAN) ( provides the following information about the BRIP1 gene's known or predicted involvement in human disease.

Breast cancer (BC): A common malignancy originating from breast epithelial tissue. Breast neoplasms can be distinguished by their histologic pattern. Invasive ductal carcinoma is by far the most common type. Breast cancer is etiologically and genetically heterogeneous. Important genetic factors have been indicated by familial occurrence and bilateral involvement. Mutations at more than one locus can be involved in different families or even in the same case. Disease susceptibility is associated with variations affecting the gene represented in this entry.

Fanconi anemia complementation group J (FANCJ): A disorder affecting all bone marrow elements and resulting in anemia, leukopenia and thrombopenia. It is associated with cardiac, renal and limb malformations, dermal pigmentary changes, and a predisposition to the development of malignancies. At the cellular level it is associated with hypersensitivity to DNA-damaging agents, chromosomal instability (increased chromosome breakage) and defective DNA repair. The disease is caused by mutations affecting the gene represented in this entry.

NCBI Gene ( lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the BRIP1 gene.
  • Familial cancer of breast
  • Fanconi anemia, complementation group J
  • Tracheoesophageal fistula (, a catalog designed for genetics professionals and researchers, provides the following information about the BRIP1 gene and its association with health conditions.

Where is the BRIP1 gene located?

Cytogenetic Location: 17q22.2

Molecular Location on chromosome 17: base pairs 61,679,186 to 61,863,937

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBI (

The BRIP1 gene is located on the long (q) arm of chromosome 17 at position 22.2.

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 61,679,186 to base pair 61,863,937 on chromosome 17.
