Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4BP6
The NM_000059.4(BRCA2):āc.7025A>Cā(p.Gln2342Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000069 in 1,449,866 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). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q2342R) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 26, 2023 | The p.Q2342P variant (also known as c.7025A>C), located in coding exon 13 of the BRCA2 gene, results from an A to C substitution at nucleotide position 7025. The glutamine at codon 2342 is replaced by proline, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
