Understanding Ring chromosome 1
Features vary from person to person. Most commonly they include slow growth before and after birth, developmental delay, intellectual disability, a small head size, and distinct facial features. Less common features include differences in a brain structure, a heart hole, and curved feet. It starts at birth.

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