Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3
The NM_024675.4(PALB2):c.2619T>A(p.Ser873Arg) 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 pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another nucleotide change resulting in same amino acid change has been previously reported as Uncertain significancein ClinVar.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 13, 2023 | The p.S873R variant (also known as c.2619T>A), located in coding exon 7 of the PALB2 gene, results from a T to A substitution at nucleotide position 2619. The serine at codon 873 is replaced by arginine, an amino acid with dissimilar properties. An alteration resulting in the same amino acid substitution, p.S873R (c.2617A>C), has been reported in 1 of 1824 patients with triple negative breast cancer (Couch FJ et al. J. Clin. Oncol. 2015 Feb;33:304-11). This amino acid position is highly 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. - |
