BRCA1 and posterior cortical atrophy: To reveal the status of BRCA germline mutations in the Chinese PCa population, 172 patients with PCa with BRCA germline mutations diagnosed at multiple centers were screened for: (1) retrospective statistical analysis of the Chinese PCa population with BRCA germline mutations in different pathological stages; (2) exploring the variant distribution and type, and the associated somatic mutations of the BRCA1/2 mutations.
