Family planning The optimal time for determination of genetic risk and grsig of the availability of prenatal testing is before pregnancy. The polydactyly is most commonly preaxial in the feet and postaxial in the hands, with variable cutaneous syndactyly, but the limb findings vary significantly.

Mutations in the GLI3 gene cause Greig cephalopolysyndactyly syndrome. For more information, see Table A. Affected cephalopolysyndactylyy may exhibit several bone abnormalities of the face and head craniofacial dysostosisincluding a short, pointed head acrobrachycephaly and widely spaced eyes ocular hypertelorism.

By interacting with certain genes at specific times during development, the GLI3 protein plays a role in the normal shaping patterning of many organs and tissues before birth. Retrieved from ” https: Syjdrome daughter, of above average intelligence, had polysyndactyly and a peculiar skull shape in the form of expanded cranial vault leading to high forehead and bregma, with no evidence of precocious closure of cranial sutures.

GeneReviews staff have not independently verified the classification of variants. Prognosis The prognosis for is generally excellent.


Greig cephalopolysyndactyly syndrome

Causes GCPS is inherited in an autosomal dominant pattern. Note on variant classification: Sophisticated imaging, especially of the CNS, is not routinely indicated unless the clinician detects findings or symptoms that specifically indicate such an evaluation. Oro-facial-digital syndrome is a rare genetic disorder in which there have been many cephalopolysyndxctyly identified.

This was the first report of an interstitial deletion associated with Greig syndrome. Most of the variants have been seen in multiple unrelated persons and are not cephakopolysyndactyly to be associated with any phenotypic effects, although they have not been rigorously analyzed for subtle effects.

From Wikipedia, the free encyclopedia. The Greig polysyndactyly craniofacial dysmorphism syndrmoe If the GLI3 pathogenic variant has been identified in an affected family member, prenatal testing for pregnancies at increased risk may be available from a clinical laboratory that offers either testing of this gene or custom prenatal testing.

Additional physical abnormalities may be present in some patients. A bonus to all MIMmatch users is cephalopolysyndacttly option to sign up for updates on new gene-phenotype relationships.


Other low frequency findings include central nervous system CNS anomalies, hernias, and cognitive impairment. Etiological heterogeneity and clinical characteristics of metopic synostosis: The skin between the fingers and toes may be fused cutaneous syndactyly.

The main clinical distinction was mental retardation, involving agenesis sjndrome the corpus callosum. Differential Diagnosis Acrocallosal syndrome ACLS OMIM includes pre- or postaxial polydactyly, cutaneous syndactyly, agenesis of the corpus callosum rare in GCPSwidely spaced eyes, macrocephaly, moderate to severe intellectual disability, intracerebral cysts, seizures, and umbilical and inguinal hernias.

Orphanet: Greig cephalopolysyndactyly syndrome

A significant range of severity is associated with the GCPS designation; interfamilial variability is greater than intrafamilial variability: Only comments written in English can be processed.

Zoom-in comparative genomic hybridisation arrays for the characterisation of variable breakpoint contiguous gene syndromes. Skull and gteig Craniosynostosis: One case of apparent non- penetrance has been reported [ Debeer et al ].

There is no evidence for genetic anticipation in GCPS. High resolution chromosome analysis showed a 46,XX,del 7 p13p14 pat chromosome pattern. Turn recording back on. The diagnosis should be made with caution in infants with multiple other malformations, especially in the absence of a positive family history.

Other family members of a proband. The diagnosis of GCPS is based on clinical findings and family history.
