IDH1 Mutational Analysis
Indication:
To detect and type mutations in exon 4 of the IDH1 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 80 to 138 in exon 4 of IDH1.
Test Parameters:
This assay will detect mutations present in exon 4 of IDH1. 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, 5g 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.
