Gene Variant Descriptions | RB1 H483Y lies within domain A of the Rb1 protein (UniProt.org). H483Y has been identified in the scientific literature (PMID: 29236940, PMID: 33539671), but has not been biochemically characterized and therefore, its effect on Rb1 protein function is unknown (PubMed, May 2024). |

RB1 H483Y | Her2-receptor negative breast cancer | predicted - resistant | Letrozole + Ribociclib | Case Reports/Case Series | Actionable | In a clinical case study, RB1 H483Y was identified in the circulating tumor DNA of a patient with estrogen receptor (ESR1)-positive, progesterone receptor (PGR)-positive, and Erbb2 (Her2)-negative, invasive ductal carcinoma at the time of disease progression after 13 months of Kisqali (ribociclib) and Femara (letrozole) combination treatment (PMID: 29236940). | 29236940 |
