Pfeiffer syndrome is a rare genetic disorder, characterized by the premature fusion of certain bones of the skull ( craniosynostosis ), which affects the shape of the head and face. The syndrome includes abnormalities of the hands and feet, such as wide and deviated thumbs and big toes. Pfeiffer syndrome is caused by mutations in the fibroblast ...
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. Signs and symptoms. Features of this condition include: Abnormal heart morphology
View/Edit Mouse. Fibroblast growth factor receptor 2 ( FGFR2) also known as CD332 ( cluster of differentiation 332) is a protein that in humans is encoded by the FGFR2 gene residing on chromosome 10. [5] [6] FGFR2 is a receptor for fibroblast growth factor . The protein encoded by this gene is a member of the fibroblast growth factor receptor ...
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 genes.
Marfan syndrome ( MFS) is a multi-systemic genetic disorder that affects the connective tissue. [6] [7] [1] Those with the condition tend to be tall and thin, with long arms, legs, fingers, and toes. [1] They also typically have exceptionally flexible joints and abnormally curved spines. [1]
Acrocephalosyndactyly. Acrocephalosyndactyly is a group of congenital conditions characterized by irregular features of the face and skull ( craniosynostosis) and hands and feet ( syndactyly ). [1] Craniosynostosis occurs when the cranial sutures, the fibrous tissue connecting the skull bones, fuse the cranial bones early in development.
Crouzon syndrome is an autosomal dominant genetic disorder known as a branchial arch syndrome. Specifically, this syndrome affects the first branchial (or pharyngeal) arch, which is the precursor of the maxilla and mandible. Because the branchial arches are important developmental features in a growing embryo, disturbances in their development ...
Patients with Crouzon syndrome sometimes exhibit malformations of the external ear and/or the middle ear, such as malalignment of the pinna (Peterson-Falzone et al., 2001). Literature has suggested that persons with Crouzon syndrome typically have conductive hearing loss caused by middle ear effusion (or fluid in the middle ear) and perforation ...
