Cancers of adrenal (7/10 cancer samples expressed TRK-A), pancreas (5/17 TRK-A), ovary (7/20 TRK-A), esophagus (9/20 TRK-A and ROS1), urinary bladder (6/22 TRK-A), and endometrium (9/17 ROS1) expressed increased levels of TRK-A and/or ROS1, compared to corresponding normal samples. Here, NTRK1 is linked to cancer.
