There are three main types of Pfeiffer syndrome: type I is the mildest and most common; type II is the most severe, with neurological problems and a cloverleaf deformity; and type III is similar to type II, but without the cloverleaf deformity.
Currently, Noack syndrome (ACPS type I) is now classified as Pfeiffer syndrome (ACS type V); Goodman syndrome (ACPS type IV) is classified as a variation of Carpenter syndrome (ACPS type II); and different researchers have combined Apert (ASC type I), Crouzon (ASC type II), and Pfeiffer (ASC type V) syndrome into Apert-Crouzon and Crouzon ...
Rarely, a mutation in a gene other than those currently known may be responsible for a Waardenburg syndrome with features of type 2. This is usually initially classified as simply type 2 but may be given its own subtype once a gene or locus is identified and established.
Holden is one of 1 in 100,000 children born with a genetic disorder called Pfeiffer syndrome. It is associated with more than 25 mutations on one of two fibroblast growth factor receptor...
Carpenter syndrome, also called acrocephalopolysyndactyly type II, is an extremely rare autosomal recessive congenital disorder characterized by craniofacial malformations, obesity, syndactyly, and polydactyly.
The syndrome is caused by a mutation in a gene on chromosome 10 that controls the body's production of fibroblast growth factor receptor 2 (FGFR2). Crouzon syndrome is named for Octave Crouzon, a French physician who first described this disorder.
Cardiocranial syndrome, Pfeiffer type is a rare multiple disorder syndrome characterized by congenital heart defects, sagittal craniosynostosis, and severe developmental delay. The condition has been reported in less than 10 patients worldwide. [1] [2] [3] [4]
Type 2 have mutations in the protein transport protein Sec24D gene located on the long arm of chromosome 4 (4q26). A third type has been described with a mutation in the cartilage associated protein located on the short arm of chromosome 3 (3p22.3).
Prince's ex-wife Mayte Garcia opened up in a new interview with People to talk about her time with the late singer.
Advanced paternal age may be associated with a higher risk for certain single-gene disorders caused by mutations of the FGFR2, FGFR3 and RET genes. These conditions are Apert syndrome, Crouzon syndrome, Pfeiffer syndrome, achondroplasia, thanatophoric dysplasia, multiple endocrine neoplasia type 2, and multiple endocrine neoplasia type 2b.
