Genes affected

RAB5A (HGNC:9783): (RAB5A, member RAS oncogene family) Enables GDP binding activity; GTP binding activity; and GTPase activity. Involved in several processes, including amyloid-beta clearance by transcytosis; early endosome to late endosome transport; and regulation of exocytosis. Located in several cellular components, including cytoplasmic side of early endosome membrane; nucleoplasm; and terminal bouton. [provided by Alliance of Genome Resources, Apr 2022]

The c.370C>G (p.P124A) alteration is located in exon 4 (coding exon 3) of the RAB5A gene. This alteration results from a C to G substitution at nucleotide position 370, causing the proline (P) at amino acid position 124 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
