What causes Greig syndrome?
GCPS is caused by abnormal variants in the GLI3 gene. Most of the variants in GLI3 that cause the disorder are single nucleotide changes, deletions or insertions. Less commonly, patients have larger insertions or deletions of the gene.
What is Greig syndrome?
Greig cephalopolysyndactyly syndrome is a disorder that affects development of the limbs, head, and face. The features of this syndrome are highly variable, ranging from very mild to severe.

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.
What is the pathophysiology of polydactyly of the finger or toes?
Polydactyly of the finger or toes as well as cutaneous syndactyly are common. Greig cephalopolysyndactyly is associated with GLI3 mutations on chr7p14.150and is primarily autosomal dominant. McKusick-Kaufman Syndrome McKusick-Kaufman syndrome is characterized by 3 features: heart defects, genital abnormalities, and polydactyly.
What is GCPS (Greig’s syndrome)?
Greig cephalopolysyndactyly syndrome (GCPS) is a rare genetic disorder characterized by physical abnormalities affecting the fingers and toes (digits) and the head and facial (craniofacial) area.
Is polydactyly common in Pallister-Hall syndrome (PHS)?
Polydactyly is among comnion extremity abnormalities. Mutations of GLI3 gene have been reported commonly in Greig Cephalopolysyndactyly Syndrome (GCPS) and Pallister-Hall Syndrome (PHS). We have determined two different mutations of GLI3 gene in two different cases, one of which is with GCPS and the other one is with PHS.
