LOINC Code


LOINC code70289-4
nameDel(1)(p32p32)(STIL,TAL1) fusion transcript [Presence] in Blood or Tissue by Molecular genetics method
descriptionThis term is used to identify a leukemia causing gene deletion at 1p32 resulting in a gene fusion between STIL and TAL1 where the STIL promoter controls TAL1. The term was created for (but not limited to) DNA Technology's HemaVision HV01-28N kit, a qualitative in vitro diagnostic test for 28 leukemia causing chromosomal alterations including more than 80 breakpoints plus associated mRNA splice variants. Reverse transcription followed by multiplex nested polymerase chain reactions (RT-PCR) and agarose gel electrophoresis are used to identify gene fusions caused by chromosomal translocations, gene deletions or inversions. Testing information is useful for predicting development of the disease and selection of treatment.

Fully-Specified Name

componentDel(1)(p32p32)(STIL,TAL1) fusion transcript
propertyPrThr  =  Present or threshold:  The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold.
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemBld/Tiss
    Bld  =  Whole blood
    Tiss  =  Tissue, unspecified
scaleOrd  =  Ordinal:  Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive.
methodMolgen  =  Molecular Genetics:  General class of methods used to detect genetic attributes on a molecular basis including RFL, PCR and other methods.

History/Usage

first released
last updated2.56
last change typeMIN  - change to field other than name
change reasonThe PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
