The condition has been linked with genetic mutations in genes that code for certain ion channels, such as the L-type calcium channel α1-subunit (Ca v 1.1) and potassium inward rectifier 2.6; it is therefore classified as a channelopathy.
The condition has been linked with genetic mutations in genes that code for certain ion channels that transport electrolytes (sodium and potassium) across cell membranes. The main ones are the L-type calcium channel α1-subunit (Ca v 1.1) and potassium inward rectifier 2.6; it is therefore classified as a channelopathy.
