Impact List | missense |
Protein Effect | unknown |
Gene Variant Descriptions | SF3B1 H662D lies within HEAT repeat 4 of the Sf3b1 protein (UniProt.org). H662D results in aberrant splicing in patient samples (PMID: 31474574), but has not been fully biochemically characterized, and therefore, its effect on Sf3b1 protein function is unknown. |

SF3B1 H662D | chronic lymphocytic leukemia | predicted - sensitive | Sudemycin D1 | Preclinical - Patient cell culture | Actionable | In a preclinical study, Sudemycin D1 treatment resulted in increased cytotoxicity (p<0.05) in chronic lymphocytic leukemia cells derived from patients harboring mutations in SF3B1 (n=14) or other RNA splicing/processing genes (n=8) compared to cells derived from patients without mutations (n=10) in culture, including 1 cell line harboring SF3B1 H662D (PMID: 26068951). | 26068951 |
