Only SF3B1 Mutation involving K700E Independently Predicts Overall Survival in Myelodysplastic Syndromes
[Paper-level Aggregated] PMCID: PMC10015977
Evidence Type(s): Prognostic
Summary: Mutation: K700E | Summary: The K700E mutation in SF3B1 is associated with a favorable prognosis in myelodysplastic syndromes (MDS), correlating with significantly better overall survival (OS) outcomes compared to non-K700E mutations and SF3B1 wild-type patients. It is linked to specific clinical features, such as a higher percentage of ring sideroblasts and lower comprehensive cytogenetic scoring system (CCSS) scores, indicating its relevance in predicting disease outcomes. However, some evidence suggests that the K700E mutation may not show significant differences in OS compared to other SF3B1 mutations, indicating variability in its prognostic significance.
Evidence Type: Prognostic Mutation: R625 | Summary: The presence of the R625 mutation, as a recurrent mutation in MDS, may correlate with disease outcomes in patients, independent of therapy.
