Gene SF3B1
Variant R1297C
Impact List missense
Protein Effect unknown
Gene Variant Descriptions SF3B1 R1297C lies within the SF3B3 and SF3B5-interacting region of the Sf3b1 protein (UniProt.org). R1297C has been identified in sequencing studies (PMID: 24662767), but has not been biochemically characterized and therefore, its effect on Sf3b1 protein function is unknown (PubMed, Feb 2021).

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

SF3B1 mutant essential thrombocythemia not applicable N/A Guideline Prognostic The presence of at least one mutation in either SH2B3, IDH2, U2AF1, SRSF2, SF3B1, EZH2, TP53, or RUNX1 is associated with inferior overall survival in patients with essential thrombocythemia, SF3B1 mutations are also associated with inferior myelofibrosis-free survival (NCCN.org). detail...
SF3B1 mutant myelofibrosis not applicable N/A Guideline Diagnostic SF3B1 mutations aid in the diagnosis of primary myelofibrosis in the absence of JAK2, CALR, or MPL mutations (NCCN.org). detail...
SF3B1 mutant chronic lymphocytic leukemia predicted - sensitive Ibrutinib + Sudemycin D1 Preclinical - Patient cell culture Actionable In a preclinical study, Sudemycin D1 and Imbruvica (ibrutinib) combination treatment resulted in enhanced cytotoxicity in chronic lymphocytic leukemia cells derived from patients harboring SF3B1 mutations in culture (PMID: 26068951). 26068951
SF3B1 mutant myelodysplastic syndrome not applicable N/A Clinical Study Prognostic In multiple clinical studies, SF3B1 mutations were associated with better overall survival in patients with myelodysplastic syndrome (PMID: 21998214, PMID: 22096241, PMID: 24220272), but may not have independent prognostic significance (PMID: 22096241). 22096241 21998214 24220272
SF3B1 mutant 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 (PMID: 26068951). 26068951
SF3B1 mutant chronic lymphocytic leukemia predicted - sensitive Sudemycin D6 Preclinical - Pdx Actionable In a preclinical study, Sudemycin D6 treatment reduced tumor cells in the spleen and peripheral blood in patient-derived xenograft (PDX) models of chronic lymphocytic leukemia harboring SF3B1 mutations (PMID: 26068951). 26068951
SF3B1 mutant acute myeloid leukemia predicted - sensitive GSK3203591 Preclinical - Patient cell culture Actionable In a preclinical study, patient-derived acute myeloid leukemia cell lines harboring mutations in U2AF1 (n=3), SRSF2 (n=9), or SF3B1 (n=4) demonstrated increased sensitivity to GSK3203591 compared to spliceosomal wild-type cell lines in culture (PMID: 31408619). 31408619
