Genes affected

VPS53 (HGNC:25608): (VPS53 subunit of GARP complex) Involved in endocytic recycling and retrograde transport, endosome to Golgi. Acts upstream of or within lysosomal transport. Located in several cellular components, including Golgi apparatus; perinuclear region of cytoplasm; and recycling endosome. Part of EARP complex and GARP complex. Implicated in pontocerebellar hypoplasia type 2E. [provided by Alliance of Genome Resources, Apr 2022]
