Retinoblastoma is cancer of the retinal cells of the eye. A familial form is known (about 40 percent of all cases), which is caused by a dominant gene. It occurs in a frequency of about 1/17,000, usually appearing at 1 to 3 years of age. A second form of retinoblastoma is not familial (60 percent of all cases), develops later in life, and usually involves only one eye. Two mutations are thought to be required for the disease to occur.
