- Test Code: ON082
Test Description
This test is for diagnosing acute lymphoblastic leukemia (ALL), evaluate the prognosis, and determine the treatment policy. DNA is extracted from bone marrow or blood and mutation information of 49 genes is analyzed. It can detect SNV and small indel mutations, and the detection sensitivity of mutations is about 5%, and thiopurine toxicity-related gene mutations are analyzed together.

Result
The test results will be provided according to the designated TAT. Review the sample report to see how the results are structured.
Limitations
- This test was performed using sequencing analysis. It can detect SNP and small-indel variants within the analyzed region, but not structural variations such as copy number variation (CNV) and gene rearrangement.
- The limit of detection for SNV and small-indel variants is approximately 5%.
- The detected variants in this test are not re-confirmed by Sanger sequencing, ddPCR or other confirmation methods.
- This test does not distinguish between germline and somatic variants. If the variant allele frequency of the mutation is close to 50% or 100%, the possibility of a germline variant cannot be excluded.
- The variants detected in this test are classified into four (tier 1~4) according to the 2017 JMD guideline (J Mol Diagn 2017;19:313-327), and tier 4 variants are not reported.
