Alterations that cause Greig cephalopolysyndactyly syndrome GCPS range from gross cytogenetic alterations to nucleic acid substitutions.

The clinical atlas of Greig cephalopolysyndactyly syndrome. Greig cephalopolysyndactyly syndrome in a large family: Giemsa-banded karyotypes do not detect all deletions, even those on the order of 1 Mb [unpublished observations].


Rarely, affected individuals may have more serious medical problems including seizures, and developmental delay. The mutation was demonstrated to result in nonsense-mediated mRNA decay.

Greig cephalopolysyndactyly syndrome

Hui and Joyner described the molecular characteristics of the Xt mutation. They found that deficiency of expression of Gli3 in the mutant mouse is due to a deletion within the 3-prime end of the gene.

The risk to other family members depends on the genetic status of the proband’s parents: Point mutations cephalopolysyndacyyly human GLI3 cause Greig syndrome. Individuals with an OFC that is increasing faster than normal, signs of increased intracranial pressure, developmental delay, loss of milestones, or seizures should undergo appropriate CNS imaging studies to exclude hydrocephalus, other CNS abnormalities, or cerebral cavernous malformations seen in some individuals with GCPS and large deletions [ Bilguvar et al ; Author, unpublished observations].

Am J Hum Genet. The following section deals with genetic risk assessment and the use of family history and genetic testing to clarify genetic status for family members. Diagnosis GCPS is usually diagnosed at birth based upon a thorough clinical evaluation; identification of characteristic physical findings; and specialized imaging procedures, including X-rays and computed tomography CT scanning.


Genetic disorderprotein biosynthesis: The risk to the sibs of a proband depends on the genetic status of the proband’s parents:. The mother syndome syndactyly of both hands.


For a cephslopolysyndactyly summary of gene and protein information, see Table AGene. Other family members of a proband. Junction fragments were found to be distinct with no common sequences flanking the breakpoints.

Polysyndactyly and trigonocephaly with partial agenesis of corpus callosum: Most of the variants have been seen in multiple unrelated persons and are not believed to be associated with any phenotypic effects, although they have not been rigorously analyzed for subtle effects.
