Glypican-3

The GPC3 gene encodes a heparan sulfate proteoglycans which is bound to the outer membrane of cells and involved in various processes of cell growth and apoptosis. Germline deletions cause x-linked recessive Simpson-Golabi-Behmel syndrome and somatic mutations are found in Wilms tumor cells.
