WebMutations in the gene encoding for this protein, RB1 gene on one chromosome could cause a loss of the wild type gene from the other chromosome in subsequent rounds of replication. This loss of the functional suppressor prompts cells to divide unchecked. Retinoblastoma is a rare cancer that develops in immature cells of the retina.
