The VUSs included BRCA1 and BRCA2, as well as other breast cancer-associated genes, such as ATM, CDH1, CHEK2, and PALB2. Referring to the latest ClinVar database, one of the variants identified as a VUS at diagnosis was re-determined as likely pathogenic, and three of the variants identified as VUSs at diagnosis were re-determined as benign. This evidence concerns the gene PALB2 and breast carcinoma.
