Moreover, the change in PSI for these two alternative exons significantly correlated with the change in Snord67 expression in matched pairs of primary breast tumors and LN metastases (MYO18A exon 40: Pearson r = 0.54, p = 0.0066; NFYA exon 3: Pearson r = 0.51, p = 0.011; Fig. 8C, D). The gene discussed is NFYA; the disease is breast neoplasm.
