Genes affected

RGL4 (HGNC:31911): (ral guanine nucleotide dissociation stimulator like 4) This oncogene encodes a protein similar to guanine nucleotide exchange factor Ral guanine dissociation stimulator. Increased expression of this gene leads to translocation of the encoded protein to the cell membrane. The encoded protein can activate several pathways, including the Ras-Raf-MEK-ERK cascade.

The c.560T>C (p.V187A) alteration is located in exon 3 (coding exon 3) of the RGL4 gene. This alteration results from a T to C substitution at nucleotide position 560, causing the valine (V) at amino acid position 187 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
