Juvenile Myelomonocytic Leukemia Associated Exon Panel – Family F/U
|Utilization Guidelines||Tests with long turn-around times (i.e., Molecular based tests and Microarrays) should only be requested on an inpatient if the result is going to affect the inpatient management. If the patient will likely be discharged before the result will be available, the test should be requested after discharge. (NOTE: UCSF Medical Center is not reimbursed for inpatient testing).
An exception to the above may be appropriate if there is a possibility the patient will not survive to be discharged and the information is important for diagnosis and/or family decisions/management (e.g., recurrence risk).

|Synonyms||JMML Panel; CBL exons 8 & 9; KRAS exons 2 & 3; NRAS exons 2 & 3; PTPN11 exons 3, 4 & 13|
|Turn around times||2-4 weeks|
|Additional information||An interpretation of this test by a laboratory physician will automatically be performed and billed for separately.
This sequencing test sequences one exon of the following genes: CBL exons 8 & 9; KRAS exons 2 & 3; NRAS exons 2 & 3; PTPN11 exons 3, 4 & 13
Targeted, single exon, germline and family follow-up studies will only be performed when the diagnostic mutation was determined by the UCSF Molecular Diagnostics lab, or a report from another CLIA lab can be provided. Otherwise, please order "JMML Associated Exon Panel (JMML)" for testing.
