Variant summary
Our verdict is Pathogenic. Variant got 20 ACMG points: 20P and 0B. PVS1PM2PP3_ModeratePP5_Very_Strong
The NM_024675.4(PALB2):c.37G>T(p.Glu13Ter) variant causes a stop gained change. 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 Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. E13E) has been classified as Likely benign.

Genes affected
PALB2 (HGNC:26144): (partner and localizer of BRCA2) This gene encodes a protein that may function in tumor suppression. This protein binds to and colocalizes with the breast cancer 2 early onset protein (BRCA2) in nuclear foci and likely permits the stable intranuclear localization and accumulation of BRCA2.

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 20 ACMG points.
PVS1
?
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 637 pathogenic variants in the truncated region.
PM2
?
Very rare variant in population databases, with high coverage;
PP3
?
Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
PP5
?
Variant 16-23641121-C-A is Pathogenic according to our data. Variant chr16-23641121-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 920082.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Submissions by phenotype
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Jan 15, 2020 | This variant changes 1 nucleotide in exon 1 of the PALB2 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of PALB2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. - |
Familial cancer of breast Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 17, 2021 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 920082). This premature translational stop signal has been observed in individual(s) with breast cancer (PMID: 28724667). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu13*) in the PALB2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PALB2 are known to be pathogenic (PMID: 17200668, 17200671, 17200672, 24136930, 25099575). - |
