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]

The c.527C>G (p.P176R) alteration is located in exon 3 (coding exon 3) of the DND1 gene. This alteration results from a C to G substitution at nucleotide position 527, causing the proline (P) at amino acid position 176 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
