Response by Ma et al to Letter Regarding Article, 'Novel Mutation in FLNC (Filamin C) Causes Familial Restrictive Cardiomyopathy'

Recently, we reported a 4-generation family of European ancestry with restrictive cardiomyopathy and a high prevalence of atrial fibrillation.1 By exome sequencing, we identified a missense variant in affected family members in a highly conserved residue (p.V2297M) of FLNC, the gene encoding filamin C. We …
