Recurrent genomic changes in sporadic chordoma.

Selected copy number gains/losses of ≥25% frequency (occurring in at least 5 out of 20 cases from unique patients) are listed with details pertaining to cytogenetic loci, genomic position, frequency, and candidate oncogenes or tumor suppressor genes. Involved maximal ranges and smaller subranges are included (coordinates in megabases).* = ranges with cases showing slight variations within the interval.
