Question: Is Greig cephalopolysyndactyly syndrome inherited ?
Answer: How is Greig cephalopolysyndactyly syndrome inherited? Greig cephalopolysyndactyly syndrome (GCPS) is often inherited in an autosomal dominant pattern. This means that to be affected, a person only needs a change (mutation) in one copy of the GLI3 gene in each cell. In some cases, an affected person inherits a gene mutation or chromosomal abnormality from one affected parent. Other cases occur in people with no history of the condition in their family. A person with GCPS syndrome has a 50% chance with each pregnancy of passing the altered gene to his or her child.
