(5) RNA expression analysis of a cardiomyopathy gene panel showed lower MYH6, but higher MYH7 and ACTN2 levels, lower levels of Ca2+ handling genes (ATP2A2, PPP1R1A), lower hypertrophy-associated FHL2, and higher NPPA and NPPB levels in comparison to NF samples. This evidence concerns the gene MYH6 and cardiomyopathy.
