Test Description and clinical significance
Genes
FGFR4
Disease:
Lung adenocarcinoma, colon adenocarcinoma, breast invasive ductal carcinoma, cutaneous melanoma, and endometrial endometrioid adenocarcinoma
The protein encoded by this gene is a tyrosine kinase and cell surface receptor for fibroblast growth factors. The encoded protein is involved in the regulation of several pathways, including cell proliferation, cell differentiation, cell migration, lipid metabolism, bile acid biosynthesis, vitamin D metabolism, glucose uptake, and phosphate homeostasis detected by next generation sequencing.
Specimen Requirements
Collection:
FFPE sections, 5-10 sections are recommended at 4 to 10 micron. A minimum of 20 ?l of each DNA with a concentration of at least 5ng/?l and an OD260/280 ratio of 1.7-1.9 and 2.0-2.1 respectively, obtained on a spectrophotometer is required.
Stability:
FFPE blocks- Indefinitely/ FFPE Slides-4 weeks
Unacceptable Conditions:
Specimen submitted is in the incorrect fixative. Insufficient specimen (less than 10% of tumor). Unlabeled or improperly labeled specimens. Decalcified specimens. Improperly stored DNA or RNA.
Storage & Transport
Store FFPE blocks and slides at room temperature. Genomic DNA must be stored at 2–8°C for several weeks post extraction, then at –15 to –25°C for long term storage
