“…This allows clinicians to screen patients for susceptibility variants prior to treatment and select an alternative treatment or co-administer protective adjuvant therapy or development modified chemotherapeutics that bypass off-target pathways. Candidate gene association studies (CGAS) in which frequencies of genetic variants, mainly single nucleotide polymorphisms (SNPs) are compared between cases and controls, and genome-wide association studies (GWAS), in which genetic variations across the whole genome are analyzed, are 2 widely used methods to identify variants that may contribute to drug-specific risk factors (Pinheiro et al, 2020). However, while these studies help identify numerous genetic variants, they need further validations in order to determine the causal relationship between genetic variants and occurrence of cardiotoxicities, which is essential for further development of protective therapy (Knowles et al, 2018).…”
