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.38G>A (p.S13N) 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 38, causing the serine (S) at amino acid position 13 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
