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.

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: The BRIP1 c.2220G>T (p.Gln740His) variant involves the alteration of a non-conserved nucleotide. 3/4 in silico tools predict a damaging outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in 58/133810 control chromosomes at a frequency of 0.0004335, which is approximately 7 times the estimated maximal expected allele frequency of a pathogenic BRIP1 variant (0.0000625), suggesting this variant is likely a benign polymorphism. This variant has been reported in multiple cancer patients, however, a case-control study showed that this variant was not associated with breast cancer (OR=0.638, P=0.49, Haiman_2013). In addition, two patients carry the variant of interest and a pathogenic variant, homozygous MUTYH c.1187G>A/p.Gly396Asp and PALB2 c.3113G>A/W1038X, respectively (Yurgelun_2015, Kahn_2016), suggesting the variant of interest may be benign. On the other hand, multiple clinical diagnostic laboratories/reputable databases classified this variant as uncertain significance. Taken together, this variant is classified as likely benign. -

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. -

Malignant tumor of breast

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The BRIP1 p.Gln740His variant was identified in 32 of 48608 proband chromosomes (frequency: 0.0007) from individuals or families with breast, ovarian cancer or Lynch syndrome and was present in 7 of 14818 control chromosomes (frequency: 0.0006) from healthy individuals (Easton 2016, Jalkh 2017, Li 2015, Penkert 2018, Ramus 2015, Tung 2015, Yurgelun 2015). The variant was also identified in dbSNP (ID: rs45589637) as "With other allele", ClinVar (classified as uncertain significance by Invitae, Ambry Genetics and nine other submitters; as likely benign by Integrated Genetics/Laboratory Corporation of America and GeneDx). The variant was identified in control databases in 144 of 277004 chromosomes at a frequency of 0.0005 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 2 of 24024 chromosomes (freq: 0.00008), Other in 4 of 6460 chromosomes (freq: 0.0006), Latino in 48 of 34414 chromosomes (freq: 0.001), European in 82 of 126532 chromosomes (freq: 0.0007), Ashkenazi Jewish in 2 of 10148 chromosomes (freq: 0.0002), Finnish in 6 of 25780 chromosomes (freq: 0.0002); it was not observed in the East Asian, and South Asian populations. The p.Gln740 residue is 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 2 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. 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. -
