WebThe inversion inv(16)(p13q22) and the translocation t(16;16)(p13q22) result in the formation of the chimeric gene CBFB-MYH11, which encodes the fusion protein CBFb-SMMHC. The inv(16) mutation is reported in almost all patients with the M4Eo (M4 with eosinophilia) AML subtype according to FAB, which constitutes about 5–8% of all patients with AML. WebOct 24, 2024 · The gene was identified as part of a fusion gene with MYH11 (160745) in leukemic cells derived from patients with acute myeloid leukemia type M4Eo (see AML, 601626), which is commonly associated with a pericentric inversion of chromosome 16, inv(16)(p13q22). The MYH11 gene maps to 16p13 and the CBFB gene maps to 16q22.

It belongs to a group of proteins called myosins, which are … WebIt is recognized by the detection of the CBFB-MYH11fusion which confers a favorable prognosis, irrespective of the presence of secondary cytogenetic abnormalities. However, the effect of additional genetic anomalies on the behavior of inv(16) AML is debatable.
WebReal-time RT-PCR for quantitative detection of the inv (16) CBFB-MYH11 fusion transcript. Positive results are reported as ratio of the amount of fusion transcript with the amount of transcript from a normal control gene. This assay identifies type A fusions, which account for >90%. Analytical sensitivity is 1 tumor cell in 10,000 normal cells.
