Genes affected

HBEGF (HGNC:3059): (heparin binding EGF like growth factor) Enables growth factor activity and heparin binding activity. Involved in several processes, including epidermal growth factor receptor signaling pathway; positive regulation of protein kinase B signaling; and positive regulation of wound healing. Located in cell surface and extracellular space. Implicated in glomerulosclerosis and perinatal necrotizing enterocolitis. [provided by Alliance of Genome Resources, Apr 2022]
