Syndactyly; Polysyndactyly

This condition is normally discovered at birth and evaluated during the newborn hospital stay.

The health care provider will perform a physical exam and ask questions about the patient's medical history. Questions may include:

Medical history questions may include:

• Which fingers (toes) are involved?
• Have any other family members had this problem?
• What other symptoms or abnormalities are also present?

An infant with webbing may have other symptoms and signs that, when taken together, define a specific syndrome or condition. Diagnosis of that condition is based on a family history, medical history, and a physical exam.

The following tests may be done:

• Chromosome studies  
• Enzyme assays
• X-rays
• Metabolic studies
