Mcs6 human orthologous transcripts that have been reported as differentially expressed between non-diseased breast tissue and ductal carcinoma tissue encode for two phosphatases (DUSP6, PPP1R12A), a proteoglycan (EPYC), a redox regulator (TXNRD1), and two uncharacterized proteins (ALX1, ZDHHC17). The gene discussed is ALX1; the disease is breast ductal adenocarcinoma.
