Genes affected

DUSP26 (HGNC:28161): (dual specificity phosphatase 26) This gene encodes a member of the tyrosine phosphatase family of proteins and exhibits dual specificity by dephosphorylating tyrosine as well as serine and threonine residues. This gene has been described as both a tumor suppressor and an oncogene depending on the cellular context. This protein may regulate neuronal proliferation and has been implicated in the progression of glioblastoma through its ability to dephosphorylate the p53 tumor suppressor. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2015]

The c.526G>A (p.V176M) alteration is located in exon 4 (coding exon 3) of the DUSP26 gene. This alteration results from a G to A substitution at nucleotide position 526, causing the valine (V) at amino acid position 176 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
