"115 In a subsequent study, co-expression of mutant SCN1B with WT-SCN5A and WT-KCND3 (separately) induced a 55.6% decrease in peak I Na and 70.6% gain of function in I to, moreover, co-immunoprecipitation revealed structural association between Na V beta1B, Na V 1.5 and K V 4.3, suggesting that the elevated level of transient outward potassium current is predominantly responsible for pathogenesis in these cases of BrS."

"Multiple mutations of genes, SCN5A, SCN1B, SCN3B, GPD1L, CACNA1C, CACNB2, KCNE3 and KCND3, have been shown to decrease cardiac Na + and Ca 2+ channel activity or increase fast transient outward K + channel activity, and they are linked to BrS."
