Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_032043.3(BRIP1):c.3234G>T(p.Lys1078Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,864 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 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. K1078T) 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 | May 06, 2022 | This variant has not been reported in the literature in individuals affected with BRIP1-related conditions. This sequence change replaces lysine, which is basic and polar, with asparagine, which is neutral and polar, at codon 1078 of the BRIP1 protein (p.Lys1078Asn). This variant is present in population databases (rs570238270, gnomAD 0.0009%). ClinVar contains an entry for this variant (Variation ID: 1044878). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The asparagine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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 | May 23, 2022 | The p.K1078N variant (also known as c.3234G>T), located in coding exon 19 of the BRIP1 gene, results from a G to T substitution at nucleotide position 3234. The lysine at codon 1078 is replaced by asparagine, an amino acid with similar properties. This amino acid position is 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. - |
