Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_032043.3(BRIP1):c.2617A>T(p.Thr873Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 16/21 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. T873A) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 22, 2021 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 234720). This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 873 of the BRIP1 protein (p.Thr873Ser). - |

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Dec 28, 2015 | This variant is denoted BRIP1 c.2617A>T at the cDNA level, p.Thr873Ser (T873S) at the protein level, and results in the change of a Threonine to a Serine (ACC>TCC). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRIP1 Thr873Ser was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Threonine and Serine share similar properties, this is considered a conservative amino acid substitution. BRIP1 Thr873Ser occurs at a position that is not conserved and is located in the Helicase domain (Cantor 2011). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available evidence, it is unclear whether BRIP1 Thr873Ser is pathogenic or benign. We consider it to be a variant of uncertain significance. - |
