Chromosome 13 deletions in multiple myeloma

Conventional cytogenetic analysis with G banding was performed in 106 patients with multiple myeloma. Each vertical line to the right of the figure (the long arm of chromosome 13) indicates the part of chromosome 13 that was found to be deleted in one patient. With the exception of eight patients, the minimal region of deletion overlap appears to be in the 13q14 region (red arrow).
