KCNQ1OT1(redirected from LIT1)
Also found in: Acronyms.
KCNQ1OT1A gene on chromosome 11p15 that is epigenetically regulated and expressed from only one chromosome in a parent-of-origin manner. The KCNQ1OT1 transcript is thought to be non-coding, and regulates bidirectional gene silencing and the spreading of DNA methylation on the paternally inherited chromosome.
The transcript is abnormally expressed from both chromosomes (as above) in most patients with Beckwith-Wiedemann syndrome, and occurs in some cancers.
