NCIt definition : Human IKZF1 wild-type allele is located within 7p13-p11.1 and is approximately 123
kb in length. This allele, which encodes DNA-binding protein Ikaros, plays a role
in transcriptional enhancement. Truncated and mutated forms of the gene can be a factor
in acute lymphoblastic leukemia. A translocation t(3;7)(q27;p12) that fuses the gene
to the BCL6 gene is implicated in diffuse large B-cell lymphomas.;
NCIt note : Studies revealed that IKZF1 wt allele was deleted or mutated in two independent groups
of ALL patients who had high rates of relapse. Authors concluded that these patients
may have a previously unrecognized subtype(s) of ALL with very poor prognosis. NCI
