Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_032043.3(BRIP1):c.629C>T(p.Pro210Leu) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000744 in 1,611,958 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 18/24 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 Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P210S) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Uncertain:2
The p.P210L variant (also known as c.629C>T), located in coding exon 6 of the BRIP1 gene, results from a C to T substitution at nucleotide position 629. The proline at codon 210 is replaced by leucine, an amino acid with similar properties. 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. -

Familial cancer of breast;C1836860:Fanconi anemia complementation group J Uncertain:1
This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 210 of the BRIP1 protein (p.Pro210Leu). This variant is present in population databases (rs140097800, gnomAD 0.02%). 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: 530291). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt BRIP1 protein function with a negative predictive value of 95%. 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. -
