Overview:
NTRK1 (TRKA) is one of three known neurotrophic tyrosine kinase resceptors. The neurotrophins (and their receptors) help regulate the development of both the central nervous system (CNS) and the peripheral nervous systems (PNS).
Expression of TRKA in neuroblastoma is associated with low stage and age < 1yr at diagnosis. It is negatively correlated with unfavourable genetic features such as MYCN amplification and 1p deletion.
