The LAF4 gene is a member of the AF4/FMR2 family and was previously identified as a fusion partner of MLL in B-precursor ALL with t(2;11)(q11;q23), although AML1-LAF4 was in T-ALL.     ///    "however, AML1-LAF4 was associated with T-ALL as well as AML1-FGA7 in t(4;21)(q28;q22). "    ///    "Furthermore, we successfully applied bubble PCR to clone the novel AML1-LAF4 fusion transcript. "
