Lastly, there are some genetic syndromes characterized by specific mutations such as BRCA1, BRCA2 (Breast and ovarian cancer syndrome), ATM (Ataxia telangiectasia), STK11 (Peutz-Jeghers syndrome), PRSS1 (hereditary pancreatitis), MLH1, and MSH2/6 (Lynch syndrome) that are associated with PCa for a subgroup of patients, representing additional risk factors [11]. The gene discussed is BRCA1; the disease is posterior cortical atrophy.
