Living with Crossed polysyndactyly
A rare inherited limb condition with extra fingers and toes arranged in a crossed pattern between hands and feet.
Understanding Crossed polysyndactyly
People have extra digits on the thumb side of the hands and the little-toe side of the feet, or the reverse. Skin webbing between the first, second, and third toes is also common, and sometimes the fingers. It is noticed during pregnancy.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Extra little finger (polydactyly)
- Joined fingers (syndactyly)
- Extra digits on hands and feet in a crossed pattern

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