Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 4P and 2B. PM1PM2BP4_Moderate
The NM_024675.4(PALB2):c.2431C>T(p.Pro811Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,461,888 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. P811P) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Jan 24, 2023 | This missense variant replaces proline with serine at codon 811 of the PALB2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in one individual each affected with ovarian cancer (http://ithaka.rrp.demokritos.gr/CanVaS/individuals/00021798) and skin cancer (PMID: 34206535). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 26, 2019 | The p.P811S variant (also known as c.2431C>T), located in coding exon 5 of the PALB2 gene, results from a C to T substitution at nucleotide position 2431. The proline at codon 811 is replaced by serine, 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. - |
Familial cancer of breast Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 20, 2020 | 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with PALB2-related disease. ClinVar contains an entry for this variant (Variation ID: 490076). This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with serine at codon 811 of the PALB2 protein (p.Pro811Ser). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and serine. - |
