Sequencing of all the exons and the exon-intron boundaries (5373 bp) of Troponin T2 (cTnT) gene in 147 DCM patients along with 207 healthy controls had revealed a total of 15 SNPs and a 5 bp INDEL (Fig. 1A to 1M and Table 1). The gene discussed is TNNT2; the disease is familial dilated cardiomyopathy.
