A chordoma (also known as choroid meningioma, chordocarcinoma, chordoepithelioma, or notochordoma) is a malignant tumor arising from the embryonic remains of the notochord.[1]
Such malformations can occur anywhere in the bony tissue surrounding the spinal cord, though typically at its cranial or caudal end. The prevalence is about 1 in a million in the United States.
At least one susceptibility gene has been identified[2] but currently, no therapy is in sight, leaving affected patients with an average life expectancy of five to ten years after diagnosis.

- Based on comparative genomic hybridization data from four affected families, variations in the 6q27 region of the human chromosome 6 were found to be correlated with chordoma, thus suggesting the T gene as a potential susceptibility gene for the disease.
