LOINC long common name : t(4;11)(q21.3;q23)(AFF1,MLL) fusion transcript/control transcript [# Ratio] in Blood
or Tissue by Molecular genetics method;
LOINC short name : t(4;11)(AFF1,MLL)/control Bld/T;
LOINC description : A translocation involving chromosomes 4 and 11, t(4;11)(q21.3;q23), results in a fused
transcript between AFF1 and MLL genes. The AFF1-MLL fusion gene is associated with
childhood and adult acute lymphoblastic leukemia (ALL) as well as infant acute leukemia.
This code is based on, but not limited to, Ispogen's FusionQuant kit, which uses
real-time Quantitative RQ-PCR to quantify the expression level of specific AFF1-MLL
fusion transcripts relative to a control gene transcript (e.g. ABL1). Standard curves
of known amounts of both the control and fusion transcript are used to calculate the
ratio of the fusion transcript signal to the control gene signal.;
