Genes affected

NDFIP2 (HGNC:18537): (Nedd4 family interacting protein 2) Enables WW domain binding activity. Involved in negative regulation of gene expression; negative regulation of transport; and positive regulation of protein ubiquitination. Located in several cellular components, including Golgi apparatus; mitochondrion; and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]
