Prenatal Testing and Diagnosis for Syndactyly and Polydactyly
This fusion can occur in the soft tissues, such as the skin and nerves, or it can involve the bones themselves. However, the diagnostic process may involve genetic testing to identify specific syndromes if these conditions are part of a broader genetic disorder.

This condition is one of the most common congenital limb differences and can manifest as a fully formed extra finger or toe with its own bone, or as a small piece of soft tissue without bones.
Prenatal Testing for Syndactyly and Polydactyly Diagnosis
