Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_024675.4(PALB2):c.2038G>T(p.Gly680Ter) variant causes a stop gained 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 Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. G680G) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Sep 12, 2023 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Feb 08, 2023 | This sequence change creates a premature translational stop signal (p.Gly680*) 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). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PALB2-related conditions. For these reasons, this variant has been classified as Pathogenic. - |
not provided Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Nov 16, 2022 | Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss of function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); Has not been previously published as pathogenic or benign to our knowledge - |
