“…In the past, genetic testing was based only on the high-penetrance genes such as BRCA1 and BRCA2 , which account for around 12 to 15% of ovarian cancers (OC) and 3 to 5% of breast cancers (BC) in most populations worldwide [ 4 ]. In the last years, it has been observed that HCPS, such as BC and OC, endometrial, gastric and colon cancers, are also associated with other genes such as PALB2 , MLH1 , MSH2 , PMS1 , PMS2, MSH6, TP53 , CDH1 , SKT11 and PTEN [ 4 ].…”
