Prevalence of cardiac ion channelopathies in SIDS victims, based on data from population-based cohort studies (Tables 5 and 6). Blue bars indicate the prevalence of mutations and red bars that of mutations with a known malignant phenotype. (a) Mutations in genes affecting the fast sodium current I Na. (b) Mutations in genes affecting the transient outward potassium current I to (KCND3), the slow delayed rectifier potassium current I Ks(KCNQ1 and KCNE1), the rapid delayed rectifier potassium current I Kr (KCNH2 and KCNE2), the inward rectifier potassium current I K1 (KCNJ2), the ATP-sensitive potassium current I K,ATP (KCNJ8), the RyR2 calcium release channel (RYR2), and the gap junctional current I j (GJA1).
