However, numerous studies show that children with DCM can carry different somatic mutations in exon 17 of KIT (D816V, D816Y, or D816I), as well as mutations in other exons (Del419, K509I, or internal tandem duplication A502_Y503dup) [18,35,36,37,38,39,40,41]. The gene discussed is KIT; the disease is familial dilated cardiomyopathy.
