Genetic Mosaicism in Calmodulinopathy

Abstract excerpt

Background: CaM (calmodulin) mutations are associated with congenital arrhythmia susceptibility (calmodulinopathy) and are most often de novo. In this report, we sought to broaden the genotype-phenotype spectrum of calmodulinopathies with 2 novel calmodulin mutations and to investigate mosaicism in 2 affected families. Methods: CaM mutations were identified in 4 independent cases by DNA sequencing. Biochemical...
