Genes affected

ARHGEF26 (HGNC:24490): (Rho guanine nucleotide exchange factor 26) This gene encodes a member of the Rho-guanine nucleotide exchange factor (Rho-GEF) family. These proteins regulate Rho GTPases by catalyzing the exchange of GDP for GTP. The encoded protein specifically activates RhoG and plays a role in the promotion of macropinocytosis. Underexpression of the encoded protein may be a predictive marker of chemoresistant disease. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

The c.95G>A (p.R32Q) alteration is located in exon 2 (coding exon 1) of the ARHGEF26 gene. This alteration results from a G to A substitution at nucleotide position 95, causing the arginine (R) at amino acid position 32 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
