Summary

Fusion gene

IGL/BCL9 IGL (22q11.22) BCL9 (1q21.2) M t(1;22)(q21;q11)

Note

the 2 translocations t(1;14)(q21;q32) and t(1;22) are variants of each other
This t(1;14)(q21;q32) with BCL9 involvement is different from the t(1;14)(q21;q32) with FCGR2B involvement, from the t(1;14)(q21;q32) with MUC1 involvement and from the t(1;14)(q21;q32) with IRTA1 involvement.
