Reported in ClinVar with conflicting interpretations of pathogenicity (ClinVar Variant ID# 132676; Landrum et al., 2016); In vitro functional studies show a reduction in potassium channel current and abnormal KCNQ1 protein trafficking (Ohno et al., 2006; Harmer et al., 2010); however additional studies are needed to validate the functional effect of this variant in vivo; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 27535533, 30123799, 29766885, 29261713, 29672598, 30530868, 30461122, 31447099, 32058015, 31941373, 17341399, 16684966, 24606995, 19862833, 16945797, 16922724, 10973849, 21070882, 23861362, 24710009, 19907016)
