Genes affected
DND1 (HGNC:23799): (DND microRNA-mediated repression inhibitor 1) This gene encodes a protein that binds to microRNA-targeting sequences of mRNAs, inhibiting microRNA-mediated repression. Reduced expression of this gene has been implicated in tongue squamous cell carcinoma. Two pseudogenes of this gene are located on the long arm of chromosome 17. [provided by RefSeq, Dec 2010]
WDR55 (HGNC:25971): (WD repeat domain 55) Predicted to be involved in rRNA processing. Located in nucleolus and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
