Understanding Your Results

NTRK3 test results indicate the presence or absence of gene rearrangements. A positive result suggests a mutation that may be linked to cancer or neurological conditions, while a negative result indicates no detectable rearrangement. Consult a genetic counselor or oncologist for detailed interpretation.
📊

Positive

NTRK3 gene rearrangement detected. Associated with increased risk of cancer or neurological disorders. Further clinical evaluation and targeted therapy options may be considered.

📊

Negative

No NTRK3 gene rearrangement detected. Does not completely rule out other genetic conditions. Clinical correlation recommended.

⚠️ When to Consult a Doctor:

Consult a doctor if you experience symptoms like tumors, developmental delays, or seizures, or if test results are positive. Genetic counseling is advised for family planning and management.
