Is polydactyly genetic?
In almost 14% of all patients, this type of polydactyly is hereditary. It usually passes on in an autosomal dominant manner with variable expression and incomplete penetrance. It is genetically heterogenic, meaning that mutations in different genes can be the cause.
How does polydactyly affect a person’s life?
The life expectancy for people with polydactyly is the same as a normal person without the disorder. What restrictions does it have? If the extra finger or toe is removed, then most children will have full range of motion with their other fingers and toes.
Why are some babies born with extra fingers and toes?
Causes: As a baby develops in the mother’s uterus, the hand or foot starts out in the shape of a paddle. The paddle splits into separate fingers or toes. In some cases, too many fingers or toes form. Diagnosis: The extra digit may be connected by skin, muscle, or bone.
