On the basis of relational studies, five cancerous sensitive loci have been assumed for the prostate cancer, especially for inherited prostate cancer: Those loci whose HPC1 are restricted to q24-251 chromosome, those loci whose PCAP are limited to q42.2-431, those loci whose CAPB are restricted to P361, those loci whose HPCX are limited to Xq27-28 and those loci whose HPC20 are restricted to q1320. Here, CSAD is linked to prostate carcinoma.
