Genes affected
BRIP1 (HGNC:20473): (BRCA1 interacting helicase 1) 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.

Submissions by phenotype
Familial cancer of breast;C1836860:Fanconi anemia complementation group J Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 26, 2020 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in BRIP1 are known to be pathogenic (PMID: 16116423, 17033622, 21964575). This variant has not been reported in the literature in individuals with BRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 530302). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Glu150*) in the BRIP1 gene. It is expected to result in an absent or disrupted protein product. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 20, 2022 | The p.E150* variant (also known as c.448G>T), located in coding exon 4 of the BRIP1 gene, results from a G to T substitution at nucleotide position 448. This changes the amino acid from a glutamic acid to a stop codon within coding exon 4. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. - |
Familial cancer of breast Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | May 31, 2023 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |
