Pfeiffer syndrome acrocephalosyndactyly type V is generally accepted to be the same condition as Noack syndrome acrocephalopolysyndactyly type I. The features of this syndrome are highly variable, ranging from very mild to severe. If the patient has significant developmental delay or intellectual disability, CGH analysis should be done first, followed by sequence analysis of GLI3and then Giemsa-banded karyotyping if no GLI3 pathogenic variant has been identified by the other two methods.
A minority of individuals with PHS show multiple severe anomalies such as pituitary dysplasia with panhypopituitarism and laryngeal clefts or other airway anomalies, which may be life threatening in the neonatal period.

For information about clinical trials conducted in Europe, contact: A number sign is used with this ssyndrome because of evidence that Greig cephalopolysyndactyly syndrome GCPS is caused by heterozygous mutation in the GLI3 gene on chromosome 7p Monitoring for evidence of occipitofrontal circumference OFC increasing faster than normal.
Point mutations in human GLI3 cause Greig syndrome. Two individuals with a severe GCPS phenotype that overlaps with acrocallosal syndrome see Figure 1 have been found to have a pathogenic missense variant in GLI3 [ Elson et alSpeksnijder et al ]. geeig

In a particularly instructive family in which cephaloplysyndactyly members of 4 generations could be studied clinically and molecularly, a missense mutation, RW The breakpoints were within the first third of the coding sequence.
Disorders inherited in a dominant pattern occur when only a single copy of an abnormal gene is necessary for the appearance of the disease. In addition, mouse models support the hypothesis that haploinsufficiency is the mechanism.
GLI3 frameshift mutations cause autosomal dominant Pallister-Hall syndrome. Macrocephaly is defined as a head circumference greater than the syndeome centile compared to appropriate age and sex standards. A bonus to all MIMmatch users is the option to sign up for updates on new gene-phenotype relationships.
Winter and Huson called attention to the evidence that, on both morphologic and comparative gene mapping grounds, Greig cephalopolysyndactyly syndrome is homologous to the mouse mutant ‘extra toes’ Xt on mouse chromosome Orphanet J Rare Dis.
