| description | Translocations between chromosomes 8 and 21, resulting in a fused transcript between RUNXT1 (8q22) and RUNX1 (21q22.3), can be detected with real-time PCR. An endogenous control gene transcript (e.g. ABL1, GUS or BCR) is amplified along with the fusion transcript of interest. 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. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | t(8;21)(q22;q22.3)(RUNX1T1,RUNX1) fusion transcript/control transcript | ||
| property | NRto = Number Ratio | ||
| 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 | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
| method | Molgen = Molecular Genetics: General class of methods used to detect genetic attributes on a molecular basis including RFL, PCR and other methods. | ||
