A total of 139 VUS were identified in 30 cancer susceptibility genes, including SLX4 (n = 11), BLM (n = 10), POLE (n = 10), ATM (n = 9), CDH1 (n = 9), CHEK2 (n = 9), BRCA2 (n = 8), RAD50 (n = 7), BRIP1 (n = 6), EPCAM (n = 5), PALB2 (n = 5), PRSS1 (n = 5), TP53 (n = 5), APC (n = 4), MLH1 (n = 4), RET (n = 4), MRE11A (n = 3), MSH2 (n = 3), MSH6 (n = 3), MUTYH (n = 3), RAD51D (n = 3), STK11 (n = 3), BMPR1A (n = 2), BRCA1 (n = 2), CDKN2A (n = 1), MEN1 (n = 1), NBN (n = 1), PMS2 (n = 1), VHL (n = 1), and WT1 (n = 1) (Fig. 1b). This evidence concerns the gene TP53 and cancer.
