In fact, an additional nonsense mutation in a filamin C (FLNC) gene was found in some of the family members exhibiting early onset of DCM (Tobita et al., 2017), and genetic linkages between the FLNC gene and DCM have been reported (Ortiz-Genga et al., 2016; Reinstein et al., 2016). The gene discussed is FLNC; the disease is familial dilated cardiomyopathy.
