Living with Distal trisomy 2q

A rare chromosome condition with moderate delays in development, mild learning disability, and distinct facial features.

Understanding Distal trisomy 2q

Distal trisomy 2q is a rare condition caused by an extra piece of the long arm of chromosome 2.

People with this condition often have moderate delays in development and movement and mild intellectual disability. They may have distinct facial features and curved or bent fingers. Body measurements are normal or larger than average. Occasionally there are genital differences or short height. Signs show up in the newborn and infant years.
