| name | TPMT gene c.238G>C+460G>A+719A>G [Identifier] in Blood or Tissue by Molecular genetics method Narrative | ||
| description | Three main genetic polymorphisms [c.238G>C (rs1800462), c.460G>A (rs1800460), and c.719A>G (rs16880254)] in the TPMT gene alter metabolization efficiency of the thiopurines in 80-95% of patients. Patients with average TPMT activity are heterozygous for these genetic changes. Patients with deficient enzyme activity are homozygous for these polymorphisms. This code was created for, but not limited to, Asper Biotech's Thiopurine S-Methyltransferase Deficiency - TPMT test. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | TPMT gene.c.238G>C+460G>A+719A>G | ||
| property | Prid = Presence or identity: Prid stands for “Presence or identity”, is used for assays that detect whether or not an analyte of a particular kind is present, and if it is, to identify the specific analyte. | ||
| 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 | Nar = Narrative: Text narrative, such as the description of a microscopic part of a surgical papule test. | ||
| method | Molgen = Molecular Genetics: General class of methods used to detect genetic attributes on a molecular basis including RFL, PCR and other methods. | ||
