Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_024675.4(PALB2):c.1838del(p.Gln613ArgfsTer15) variant causes a frameshift change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Q613Q) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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.

Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Mar 30, 2023 | This variant is considered pathogenic. This variant creates a frameshift predicted to result in premature protein truncation. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 27, 2022 | The c.1838delA pathogenic mutation, located in coding exon 5 of the PALB2 gene, results from a deletion of one nucleotide at nucleotide position 1838, causing a translational frameshift with a predicted alternate stop codon (p.Q613Rfs*15). This alteration was reported in a cohort of 152 unselected Czech patients with pancreatic ductal adenocarcinoma and not in 1226 healthy controls (Borecka M et al. Cancer Genet, 2016 May;209:199-204). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. - |
