Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_032043.3(BRIP1):c.2225_2226insGTA(p.Val741_Tyr742insTer) variant causes a stop gained change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000342 in 1,461,664 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Y742Y) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Familial cancer of breast;C1836860:Fanconi anemia complementation group J Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 24, 2023 | This sequence change creates a premature translational stop signal (p.Tyr742*) 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 (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 530323). For these reasons, this variant has been classified as Pathogenic. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 07, 2022 | The c.2223_2225dupGTA pathogenic mutation (also known as p.V741_Y742ins*), located in coding exon 14 of the BRIP1 gene, results from an in-frame duplication of GTA at nucleotide positions 2223 to 2225. This results in insertion of a stop signal within coding exon 14. This variant was reported in 1/60,466 breast cancer cases and in 0/53,461 controls (Dorling et al. N Engl J Med. 2021 02;384:428-439). 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. | Jun 06, 2023 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |
