Living with Distal trisomy 10q

A rare chromosome condition with slow growth, low muscle tone, and delays in development, starting in infancy.

Understanding Distal trisomy 10q

Distal trisomy 10q is a rare condition caused by an extra piece of the long arm of chromosome 10.

People with this condition grow more slowly before and after birth. They may have low muscle tone (hypotonia), delays in development and movement, and a pattern of specific facial features. Signs show up in the newborn and infant years.

Signs & symptoms

GARD doesn't list specific symptoms for this condition separately, but the summary describes these features:

  • Slow growth before and after birth
  • Low muscle tone (hypotonia)
  • Delays in development
  • Delays in movement skills
  • A pattern of specific facial features

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