Genes affected

RALB (HGNC:9840): (RAS like proto-oncogene B) This gene encodes a GTP-binding protein that belongs to the small GTPase superfamily and Ras family of proteins. GTP-binding proteins mediate the transmembrane signaling initiated by the occupancy of certain cell surface receptors. [provided by RefSeq, Jul 2008]

Nov 14, 2024

The c.454G>A (p.V152M) alteration is located in exon 4 (coding exon 3) of the RALB gene. This alteration results from a G to A substitution at nucleotide position 454, causing the valine (V) at amino acid position 152 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
