| Gene | RB1 |
| Variant | R552* |
| Impact List | nonsense |
| Protein Effect | loss of function |
| Gene Variant Descriptions | RB1 R552* results in a premature truncation of the Rb1 protein at amino acid 552 of 928 (UniProt.org). R552* results in decreased Rb1 mRNA and protein expression, decreased nuclear localization, increased proliferation, colony formation, and migration in culture (PMID: 39845333) and due to the loss of multiple functional domains (UniProt.org), leads to a loss of Rb1 protein function. |
