Your Question

I have type 3 syndactyly and have been trying to find out what the chances are of passing this on to any children I have. Is there any research out there that covers this question?

How is syndactyly type 3 inherited?

Syndactyly type 3 has been shown to be inherited in an autosomal dominant manner.[1] This means that having only one mutated copy of the causative gene is sufficient to cause the condition. When an individual with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance of inheriting the mutated gene and a 50% chance of inheriting the normal gene and being unaffected.
