Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_ModerateBP6BP7
The NM_032043.3(BRIP1):c.1170C>T(p.Val390Val) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000347 in 1,612,964 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Submissions by phenotype
not provided Uncertain:1Benign:1
In silico analysis supports that this variant does not alter splicing; Has not been previously published as pathogenic or benign to our knowledge -
- -
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. -

Malignant tumor of breast Benign:1
The BRIP1 p.Val390= variant was not identified in the literature. The variant was identified in dbSNP (rs754755989) as “with likely benign allele” and ClinVar (interpreted as "likely benign" by Invitae, Color and Ambry Genetics). The variant was identified in control databases in 13 of 245,134 chromosomes at a frequency of 0.00005 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: and South Asian in 13 of 30,722 chromosomes (freq: 0.0004). The variant was not observed in the African, Other, Latino, European, Ashkenazi Jewish, East Asian and Finnish populations. The p.Val390= 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. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) 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 although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
Familial cancer of breast Benign:1
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
