Familial cancer of breast Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Sep 07, 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 | Aug 18, 2023 | This sequence change creates a premature translational stop signal (p.Arg238*) 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 present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with PALB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 826857). For these reasons, this variant has been classified as Pathogenic. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 06, 2023 | The p.R238* pathogenic mutation (also known as c.712A>T), located in coding exon 4 of the PALB2 gene, results from an A to T substitution at nucleotide position 712. This changes the amino acid from an arginine to a stop codon within coding exon 4. 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. - |
