| name | FLT3 gene.p.Asp835+Ile836 mutations [Presence] in Blood or Tissue by Molecular genetics method | ||
| description | Point mutations and deletions of codons D835 and I836 within the second tyrosine kinase domain (protein activation loop) of the FLT3 gene are detected by molecular genetic methods (e.g. PCR-based assays). This code was created for, but not limited to Invivoscribe's LeukoStrat(tm) FLT3 Gel Detection Mutation Assay, which detects the presence or absence of either D835 or I836 mutations within the second TKD but does not identify specific TKD mutations. FLT3-TKD mutations occur in approximately 7% of patients with acute myelogenous leukemia (AML). | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | FLT3 gene.p.Asp835+Ile836 mutations | ||
| property | PrThr = 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. | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Bld/Tiss Bld = Whole blood Tiss = Tissue, unspecified | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | Molgen = Molecular Genetics: General class of methods used to detect genetic attributes on a molecular basis including RFL, PCR and other methods. | ||
Additional Names | |||
| short name | FLT3 p.D835+I836 Bld/T Ql | ||

Associated Observations | |||
LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations. | |||
History/Usage | |||

| first released | |||
| last updated | 2.73 | ||
| last change type | MIN - change to field other than name | ||
| change reason | Release 2.71: COMPONENT: Changed for nomenclature consistency.; Previous Releases: Changed Component name to align with the current HGVS recommendations to use the three letter codes for amnio acids. In the shortname, we kept the single letter codes.; The 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. | ||
