as reported in Circulation. 2020 Feb 11;141(6):418-428 PMID: 31983240, by the International, Multicentered LQTS ClinGen Working Group:
KCNE2 was concluded to have strong evidence for acquired LQTS, however a recent comprehensive review of reported KCNE2 variants reported for LQTS demonstrated that KCNE2 variants routinely require secondary provocation to induce
phenotype, persuading the Working Group to conclude that KCNE2 has no supportive evidence as a cause of
LQTS in the absence of provoking factors (PMID: 28794082).
