dbSNP: rs118192202
rs118192202
0.010 GeneticVariation BEFREE Electrophysiological experiments revealed that the K(v)7.2 D212G substitution, neutralizing a unique negatively-charged residue in the voltage sensor of K(v)7.2 subunits, altered channel gating, leading to a marked destabilization of the open state, a result consistent with structural analysis of the K(v)7.2 subunit, suggesting a possible pathogenetic role for BFNS of this K(v)7.2 mutation. 19344764
