Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong
The NM_024675.4(PALB2):c.2674G>T(p.Glu892Ter) variant causes a stop gained change. The variant allele was found at a frequency of 0.00000547 in 1,461,884 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. E892E) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Familial cancer of breast Pathogenic:3
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 17, 2023 | ClinVar contains an entry for this variant (Variation ID: 233122). For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This premature translational stop signal has been observed in individual(s) with breast cancer (PMID: 28779002). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu892*) 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). - |
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Sep 13, 2023 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |

Hereditary cancer-predisposing syndrome Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 21, 2015 | The p.E892* pathogenic mutation (also known as c.2674G>T) located in coding exon 7 of the PALB2 gene, results from a G to T substitution at nucleotide position 2674. This changes the amino acid from a glutamic acid to a stop codon within coding exon 7. Since premature stop codons are typically deleterious in nature, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294). - |
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Jan 15, 2020 | This variant changes 1 nucleotide in exon 7 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. - |
