Test Description and clinical significance
Genes
NTRK1
Disease:
Lung adenocarcinoma, colon adenocarcinoma, breast invasive ductal carcinoma, cutaneous melanoma, and endometrial endometrioid adenocarcinoma
Molecular test that utilizes NGS technology to detect mutations in NTRK1. This gene encodes a member of the neurotrophic tyrosine kinase receptor (NTKR) family. This kinase is a membrane-bound receptor that, upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. The presence of this kinase leads to cell differentiation and may play a role in specifying sensory neuron subtypes
Specimen Requirements
Collection:
FFPE sections, 5-10 sections are recommended at 4 to 10 micron. A minimum of 20 ?l of RNA with a concentration of at least 5ng/?l and an OD260/280 ratio of 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 RNA.
Storage & Transport
Store FFPE blocks and slides at room temperature. Genomic RNA must be stored at –60 to –85°C.
