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]

The c.583G>A (p.A195T) alteration is located in exon 3 (coding exon 3) of the DND1 gene. This alteration results from a G to A substitution at nucleotide position 583, causing the alanine (A) at amino acid position 195 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
