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.
