About 40% of retinoblastoma patients have a germline <i>RB1<\/i> mutation which gives them a hereditary predisposition to develop retinoblastoma. Knowledge of the presence of an <i>RB1<\/i> mutation can help in clinical care and family planning. The Dutch National Retinoblastoma Register collects information on all Rb patients diagnosed in the Netherlands. In this paper the authors describe the results of <i>RB1<\/i> mutation scanning in 529 Dutch retinoblastoma patients from 433 independent families from the Register. We detected an <i>RB1<\/i> mutation in 92% of familial and non-familial bilateral patients. A total of 187 <i>RB1<\/i> germline mutations were found, including 33 novel mutations. Several three-generation families with incomplete penetrance <i>RB1<\/i> mutations are described.
