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]

DND1 links:

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]

The c.521C>T (p.P174L) alteration is located in exon 3 (coding exon 3) of the DND1 gene. This alteration results from a C to T substitution at nucleotide position 521, causing the proline (P) at amino acid position 174 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
