Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_024675.4(PALB2):c.1702C>T(p.Gln568Ter) 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 Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Q568Q) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 27, 2021 | The p.Q568* pathogenic mutation (also known as c.1702C>T), located in coding exon 5 of the PALB2 gene, results from a C to T substitution at nucleotide position 1702. This changes the amino acid from a glutamine to a stop codon within coding exon 5. 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. - |
Familial cancer of breast Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 18, 2020 | This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Gln568*) in the PALB2 gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in PALB2 are known to be pathogenic (PMID: 17200668, 24136930, 25099575). This variant has not been reported in the literature in individuals with PALB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 460907). - |
