Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_032043.3(BRIP1):c.629C>A(p.Pro210His) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,611,956 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/24 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P210S) has been classified as Likely benign.

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.

The BRIP1 p.Pro210His variant was not identified in the literature nor was it identified in the following databases: Cosmic, MutDB, or Zhejiang Colon Cancer Database. The variant was identified in dbSNP (ID: rs140097800) as â€šÃ„ÃºWith Uncertain significance alleleâ€šÃ„Ã¹, ClinVar (as uncertain significance by Ambry Genetics, GeneDx, Invitae, and Color Genomics), and Clinvitae (3x) databases. The variant was identified in a control database in 5 of 274722 chromosomes at a frequency of 0.000018 (Genome Aggregation Database Feb 27, 2017). It was observed in the European (Non-Finnish) population in 5 of 125584 chromosomes (freq: 0.00004); it was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, European Finnish, and SouthAsian populations. The p.Pro210 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The BRIP1 c.629C>A (p.Pro210His) variant has been reported in the published literature in in individuals with breast cancer as well as in reportedly healthy individuals (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/BRIP1)). The frequency of this variant in the general population, 0.000047 (6/128020 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The BRIP1 c.629C>A; p.Pro210His variant (rs140097800), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 231306). This variant is found in the non-Finnish European population with an allele frequency of 0.005% (6/128,020 alleles) in the Genome Aggregation Database. Computational analyses predict that this variant is neutral (REVEL: 0.139). However, given the lack of clinical and functional data, the significance of this variant is uncertain at this time. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces proline, which is neutral and non-polar, with histidine, which is basic and polar, at codon 210 of the BRIP1 protein (p.Pro210His). This variant is present in population databases (rs140097800, gnomAD 0.004%). 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: 231306). 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 disruptive. 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. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
