There is evidence that patients with cardiomyopathies caused by pathogenic or likely pathogenic variants in the DSP gene, as well as LAMA4 and MyBPC3, have signs of active myocarditis, including elevated cardiac-specific enzymes, typical inflammatory changes on magnetic resonance imaging (MRI) and positron emission tomography (PET-CT), and on morphological examination [6,7]. Here, DSP is linked to myocarditis.
