What is Trisomy 20 mosaicism?

  • Trisomy 20 mosaicism: A very rare chromosomal disorder where there is an extra copy of chromosome 20 in some of the body's cells. Some cases with this chromosomal abnormality have no clinical symptoms. The presence of abnormalities in some cases is dependent on which body cells contain the chromosomal defect.

Trisomy 20 mosaicism is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Trisomy 20 mosaicism, or a subtype of Trisomy 20 mosaicism, affects less than 200,000 people in the US population.
