PCAT1 and prostate cancer: Since the above sample set has low number of “T” allele, we evaluated all prostate cancer patients (available in cbioportal with exome/genome/SNP array data from multiple studies; see “Methods” section) who showed genetic alterations (copy number alterations or mutations) and no alterations in the PCAT1, PVT1 and MYC genes, irrespective of the ancestry and genotype at rs72725854.
