In a case report by Catapano et al. [45], a patient with fulminant myocarditis underwent DNA sequencing for 174 common cardiomyopathy-causing genes, with next-generation sequencing detecting pathogenic heterozygous variants in the form of nonsense mutations of the desmoplakin (DSP) gene associated with an unusual and severe presentation of adult-onset Still’s disease. The gene discussed is DSP; the disease is myocarditis.
