Fingers or toes may be joined all the way from the base to the tip or only partway up. What it is Syndactyly means two fingers that did not separate completely during development before birth. Early in pregnancy, the hand starts as a paddle-like structure. As the hand develops, the fingers normally separate from one another. That typically happens by approximately 8 weeks of gestation (really early!) In early human fetal development, webbing (syndactyly) of the toes and fingers is normal. At about 6 weeks of gestation, apoptosis takes place due to a protein named sonic hedgehog, also known as SHH, which dissolves the tissue between the fingers and toes, and the webbing disappears.
