Our verdict is Likely benign. Variant got -1 ACMG points: 0P and 1B. BP4

The ENST00000259008.7(BRIP1):c.3505G>T(p.Asp1169Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000992 in 1,613,194 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D1169E) has been classified as Uncertain significance.

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.

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jan 14, 2021	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in individuals with breast cancer (Easton 2016); This variant is associated with the following publications: (PMID: 32566746, 26921362) -
Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Jun 01, 2020	The BRIP1 c.3505G>T; p.Asp1169Tyr variant (rs587782029), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 141812). This variant is only observed on two alleles in the Genome Aggregation Database, indicating it is not a common polymorphism. The aspartate at codon 1169 is weakly conserved, but computational analyses (SIFT, PolyPhen-2) predict that this variant may be deleterious. Due to limited information, the clinical significance of this variant is uncertain at this time. -

Hereditary cancer-predisposing syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Sep 29, 2022	The p.D1169Y variant (also known as c.3505G>T), located in coding exon 19 of the BRIP1 gene, results from a G to T substitution at nucleotide position 3505. The aspartic acid at codon 1169 is replaced by tyrosine, an amino acid with highly dissimilar properties. This alteration was observed within 1 of 64523 individuals with a personal history of breast cancer (Easton DF et al. J Med Genet, 2016 05;53:298-309). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Nov 11, 2019	This missense variant replaces aspartic acid with tyrosine at codon 1169 of the BRIP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 2/31388 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 1169 of the BRIP1 protein (p.Asp1169Tyr). This variant is present in population databases (rs587782029, gnomAD 0.01%). 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: 141812). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
