Evaluating anthracycline cardiotoxicity associated single nucleotide polymorphisms in a paediatric cohort with early onset cardiomyopathy

Abstract

Background: Anthracyclines are a mainstay of chemotherapy. However, a relatively frequent adverse outcome of anthracycline treatment is cardiomyopathy. Multiple genetic studies have begun to dissect the complex genetics underlying cardiac sensitivity to the anthracycline drug class. A number of single nucleotide polymorphisms (SNPs) have been identified to be in linkage disequilibrium with anthracycline induced cardiotoxicity in paediatric populations. Methods: Here we screened for the presence of SNPs resulting in a missense coding change in a cohort of children with early onset chemotherapy related cardiomyopathy. The SNP identity was evaluated by Sanger sequencing of PCR amplicons from ge..
