KCNH2

A gene on chromosome 7q36.1 that encodes an alpha subunit of voltage-gated, potassium channels of the eag family.

Molecular pathology
KCNH2 mutations can cause long QT syndrome type 2.

Here we describe a rapid single-strand conformation polymorphism-heteroduplex (SSCP-HD) analysis method for screening for mutations in all coding regions of the KCNH2 and KCNE2 genes, and identify 11 KCNH2 mutations, 6 of which were novel, and several polymorphisms in 40 families with LQTS.
Intronic PCR primer sequences were designed for robust amplification of the KCNH2 and KCNE1 exons, without nesting or additives (19, 20), under identical thermocycling conditions.
