KCNQ1OT1 (potassium voltage-gated channel, KQT-like subfamily, member 1 overlapping transcript 1), a maternally imprinted lncRNA transcribed from KCNQ1 locus and responsible for transcriptional silencing a bunch of genes at KCNQ1 locus in cis by modulating histone methylation, has been found to be involved in various types of cancers [34]. Here, KCNQ1 is linked to cancer.
