Six of the nine SNPs previously identified at exome- or genome-wide significance in common variant studies of cardiomyopathy were also associated at genome-wide significance with at least one cardiac MRI phenotype in our study, including SNPs near ALPK3, BAG3, CLCNKA/HSPB7, FHOD3, FLNC, and TTN7–9. The gene discussed is FLNC; the disease is cardiomyopathy.
