IDH2 Mutation Analysis

IDH2 Mutation Analysis

Indication:  

To detect and type mutations in exon 4 of the IDH2 gene for differential diagnosis and prognostic stratification of glial tumors and acute myeloid leukemia.

Methodology:  

This test is performed by PCR-based Sanger sequencing of DNA to examine the mutation status of codons 126 to 178 in exon 4 of IDH2.

Test Parameters:  

This assay will detect mutations present in exon 4 of IDH2. The sensitivity of the Sanger sequencing assay is 20% of variant sequence in the background of wild-type sequence.

Turnaround Time:

7-10 days

Sample Requirements:
10 mL peripheral blood, 2-5mL bone marrow aspirate, 5g purified DNA, or 4-10 unstained tissue sections on glass slides along with 1 H&E-stained section.
Please provide a copy of the corresponding pathology report.
