Living with Mosaic trisomy 5
A rare chromosome condition that ranges from no signs to slow growth before birth, heart defects, and other differences.
Understanding Mosaic trisomy 5
Some people appear clinically normal. Others have slow growth before birth, heart differences (mainly a hole between the lower heart chambers), and several facial and body differences. Other differences can include a raised diaphragm, a missing corpus callosum, and an unusually shaped skull. Development may be normal even if growth measures are low. Signs are seen during pregnancy or in the newborn period.
Signs & symptoms
GARD doesn't list a set of most common symptoms for this condition. Its summary describes these features:
- Slow growth before birth
- Heart differences, mainly a hole between the lower chambers
- Eyes set widely apart

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Quick facts
This condition is caused by an extra copy of chromosome 5 in some, but not all, of the body's cells. GARD says changes in genes (also called variants) cause it.
