Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. Frequent changes to chromosome 22 include an extra piece of the chromosome in each cell (partial trisomy), a missing segment of the chromosome in each cell (partial monosomy), and a ring chromosome 22. This can lead to either a full trisomy (in which a complete third chromosome is created) or a partial trisomy (in which only part of the chromosome is copied).
