How you want to find out if you will develop cataracts? Check your YAP protein. Why? Researchers are Johns Hopkins researchers that the YAP protein “is a major target of a gene which, when mutated in humans, causes tumors to develop on nerves associated with hearing, as well as cataracts....[YAP] is linked to the NF2 tumor suppressor gene” that shapes and sizes tissue growth by coordinating control of cell proliferation and death...YAP someday could serve as a therapeutic target for those afflicted by the ringing ears, hearing loss and cataracts that characterize neurofibromatosis type 2,” according to a report posted on Newswise.
