Small Supernumerary Marker Chromosomes Additionally to Other Chromosomal Rearrangements



A small supernumerary marker chromosome can appear as a single chromosomal aberration or together with other genetic changes present in the corresponding patient. In this chapter, such cases are treated in detail, including loss or gain of gonosomes, trisomy 21, or other autosomal gain, microdeletions, the McClintock mechanism, other structural chromosomal rearrangements, and also molecular aberrations.
