TNNT2 and cardiovascular disorder: In total, we screened a total of 404 genes related to inherited cardiovascular disease using the Ion Ampliseq cardiovascular research panel14 and confirmed a previously reported heterozygous in-frame 3-base pair deletion (c.478_480del, p.Δ160E) in the TNNT2 gene in his genome and the genome of his 3 daughters (Figure 1F and 1G).
