| name | CALR gene exon 9 full mutation analysis in Blood or Tissue by Molecular genetics method | ||
| description | Full sequencing analysis of exon 9 in the CALR gene is performed to establish a diagnosis of essential thrombocythemia (ET) or primary myelofibrosis (PMF).[OMIM: 109091] All the pathologic CALR mutations reported to date are frame-shift mutations due to somatic insertions or deletions.[PMID: 24325359] Two variants, a 52-base pair deletion (c.1092_1143del, L367fs*46) and a 5-bp insertion (c.1154_1155insTTGCC, K385fs*47), are the more common and account for more than 80% of the CALR mutations seen.[PMID: 24325356] Variants outside of exon 9 are not detected by this test. | ||

Ask At Order Entry | |||
Ask at Order Entry (AOE) observations for a clinical observation or laboratory test. A LOINC term may represent a single AOE observation or a panel containing several AOE observations.
| |||
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 | |||
