Living with 7p22.1 microduplication syndrome
A rare chromosome condition that can bring delayed development, learning challenges, and distinct facial features.
Understanding 7p22.1 microduplication syndrome
It brings intellectual disability and delays in movement and speech. Facial differences can include a larger head, a prominent forehead, and wide-set eyes. Boys may have undescended testes. Heart, kidney, skeletal, and eye differences may also occur. GARD lists onset as the newborn and infant period.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Global developmental delay
- Delayed speech and language
- Motor delay

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