Genes affected

CHMP7 (HGNC:28439): (charged multivesicular body protein 7) Involved in several processes, including late endosome to vacuole transport; midbody abscission; and mitotic nuclear division. Located in cytosol; nuclear envelope; and nucleoplasm. Part of ESCRT III complex. Colocalizes with chromatin. [provided by Alliance of Genome Resources, Apr 2022]
