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]

PP2D1 (HGNC:28406): (protein phosphatase 2C like domain containing 1) Predicted to enable protein serine/threonine phosphatase activity. Predicted to be involved in protein dephosphorylation. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.
