Myriad Genetics, Inc. RCV003450463 SCV004188524 pathogenic Familial cancer of breast 2023-09-08 criteria provided, single submitter clinical testing This variant is considered pathogenic. This variant creates a frameshift predicted to result in premature protein truncation.
Ambry Genetics RCV004364753 SCV005028971 pathogenic Hereditary cancer-predisposing syndrome 2023-11-17 criteria provided, single submitter clinical testing The c.1442_1443delTT pathogenic mutation, located in coding exon 4 of the PALB2 gene, results from a deletion of two nucleotides at nucleotide positions 1442 to 1443, causing a translational frameshift with a predicted alternate stop codon (p.L481Pfs*5). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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.
