Test Name: C-MYC
C-MYC is a proto-oncogene at 8q24.1 produces short lived nuclear phosphoprotein that is overexpressed by t(8;14)(q24;q32.3), t(8;22);(q24;11) and t(2;8);(p11-12;q24), which translocate c-myc gene next to immunoglobulin genes in Burkitt’s lymphoma. C-MYC is amplified in 20-30% of breast cancer cases; associated with HER2 amplification and poor outcome. C-MYC expression in primary prostate tumor is biologically relevant and may be a predictor of future biochemical recurrence.
A formalin-fixed, paraffin-embedded (FFPE) tissue block is preferred specimen type or one (1) unbaked, unstained slide cut at 4-5 microns for H&E staining (required) and two to three (2-3) positively charged unstained slides cut at 3-4 microns for each test/antibody ordered.
Storage and Transport
