Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_032043.3(BRIP1):c.1889C>A(p.Thr630Lys) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,460,494 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. 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. T630A) has been classified as Uncertain significance.

Familial cancer of breast;C1836860:Fanconi anemia complementation group J Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 08, 2023 | This sequence change replaces threonine, which is neutral and polar, with lysine, which is basic and polar, at codon 630 of the BRIP1 protein (p.Thr630Lys). This variant is present in population databases (rs780407946, gnomAD 0.003%). 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: 530324). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BRIP1 protein function with a negative predictive value of 80%. 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 28, 2021 | The p.T630K variant (also known as c.1889C>A), located in coding exon 12 of the BRIP1 gene, results from a C to A substitution at nucleotide position 1889. The threonine at codon 630 is replaced by lysine, 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. - |
