SLC6A6 and familial dilated cardiomyopathy: For example, the taurine transporter SLC6A6 is supported by animal model data, putative GWAS associations for HCM31 and DCM32 and the use of taurine as a treatment for DCM in domesticated animals33, while the manganese superoxide dismutase SOD2 is also supported by animal model and GWAS (fibrosis phenotype) evidence.
