Transcriptional dysregulation of minor spliceosome components did not lead to overt and systematic changes in mRNA levels of MIG in this dataset, although some MIGs were found to be differentially expressed in DCM hearts (e.g. STX10, RABGGTA and C2CD3) (Fig. S5). The gene discussed is CXCL9; the disease is familial dilated cardiomyopathy.
