Using a second sample set comprised of 50 CRC patients (including cancerous and normal tissues), 50 schizophrenia patients and 52 normal controls, we studied ASE for both individual SNPs (rs9122, rs2112452, rs2227948 and rs2227947) and for the whole MCC gene (Figs 1 and 2; A, cancerous tissue; B, normal tissue from the same CRC patient; S, schizophrenia patient; N, normal control). This evidence concerns the gene MCC and schizophrenia.
