In a study on the prognosis of 52 adults with DCM carrying rare variants in sarcomeric genes (MYH6, MYH7, MYBPC3, TNNT2, and TTN), it was shown that death/HTx‐free survival dramatically decreased after 50 years of age in variant-positive patients compared with variant-negative patients.35 Here, MYBPC3 is linked to familial dilated cardiomyopathy.
