Chromosome, marker

Chromosome, marker
An abnormal chromosome that is distinctive in appearance but not fully identified. A marker chromosome is not a "marker" of a specific disease. It is a marker chromosome merely in the sense that it can be distinguished under the microscope from all of the normal human chromosomes. For example, the fragile X chromosome was once called the marker X.
