The BRIP1 p.Lys308Lys variant was not identified in the literature nor was it identified in Cosmic, MutDB and Zhejiang Colon Cancer Database. The variant was identified in dbSNP (ID: rs374974885) “With Likely benign” allele, ClinVar (classified as likely benign by Invitae and GeneDx) and Clinvitae database (2X as likely benign). The variant was identified in control databases in 12 of 276616 chromosomes at a frequency of 0.00004 increasing the likelihood that this may be a low frequency benign variant in certain populations of origin (Genome Aggregation Consortium Feb 27, 2017). The p.Lys308Lys variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site; however, the c.924A>G occurs 6 nucleotides into exon 08, and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) 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. -
Hereditary cancer-predisposing syndrome Benign:2
- -
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. -
