Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Dec 13, 2022 | Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss of function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 25186627, 27462233, 29368626, 33619228, 33807840, 35171259, 35353237, 32318955, 29625052, 29922827) - |
Pathogenic, criteria provided, single submitter | clinical testing | Quest Diagnostics Nichols Institute San Juan Capistrano | May 03, 2021 | This nonsense variant causes the premature termination of BRIP1 protein synthesis, and has been reported in individuals affected with breast, colon, or liver cancer (PMIDs: 25186627 (2015), 27462233 (2016), 29368626 (2018), 29625052 (2018), and 32318955 (2020)). The frequency of this variant in the general population is consistent with pathogenicity. Therefore, the variant is classified as pathogenic. - |
Hereditary cancer-predisposing syndrome Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 29, 2022 | The p.R581* pathogenic mutation (also known as c.1741C>T), located in coding exon 11 of the BRIP1 gene, results from a C to T substitution at nucleotide position 1741. This changes the amino acid from an arginine to a stop codon within coding exon 11. This alteration was previously identified in a breast cancer patient (Tung N et al. Cancer. 2015 Jan;121(1):25-33). In addition to the clinical data presented in the literature, 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. - |
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Jun 08, 2021 | This variant changes 1 nucleotide in exon 12 of the BRIP1 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in individuals affected with breast, colon and ovarian cancer in the literature (PMID: 25186627, 27462233, 29368626, 33807840). This variant has been identified in 5/251446 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of BRIP1 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. - |

Familial cancer of breast;C1836860:Fanconi anemia complementation group J Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 01, 2023 | This sequence change creates a premature translational stop signal (p.Arg581*) in the BRIP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BRIP1 are known to be pathogenic (PMID: 16116423, 17033622, 21964575). This variant is present in population databases (rs780020495, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with breast and colon cancer (PMID: 25186627, 27462233, 29368626). ClinVar contains an entry for this variant (Variation ID: 434539). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. - |
BRIP1-related disorder Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Dec 18, 2023 | The BRIP1 c.1741C>T variant is predicted to result in premature protein termination (p.Arg581*). This variant was reported germline/presumed germline in individuals with breast cancer, ovarian cancer, pancreatic ductal adenocarcinoma, and colon cancer (Tung et al. 2015. PubMed ID: 25186627; Harter et al. 2017. PubMed ID: 29053726; Zeng et al. 2020. PubMed ID: 32318955; Yin et al. 2022. PubMed ID: 35171259; Sorscher. 2016. PubMed ID: 27462233; Inagaki et al. 2021. PubMed ID: 33807840; Felix et al. 2022. PubMed ID: 35353237). This variant was also reported in prostate adenocarcinoma, hepatocellular carcinoma, and ovarian cancer samples (Calvo et al. 2021. PubMed ID: 33619228; Huang et al. 2018. PubMed ID: 29625052; Feng et al. 2021. PubMed ID: 33842585). This variant is reported in 0.0062% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-59858254-G-A). Nonsense variants in BRIP1 are expected to be pathogenic. This variant is interpreted as pathogenic. - |
