Of the 15 SNPs, a unique c.430 C>T transition (GenBank No. NM_000364) in exon 10 of TNNT2 gene, identified in a 29 years old male DCM patient, is of great interest, as the mutation replaces the highly conserved basic amino acid arginine at residue 144 to polar-neutral tryptophan R144W [rs483352832] (Fig. 1A). The gene discussed is TNNT2; the disease is familial dilated cardiomyopathy.
