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 ...
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 ...
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.
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.
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
Brachyturricephaly. Brachyturricephaly is a form of complex craniosynostosis (a combination of brachycephaly and turricephaly) in which the head has both an abnormally high vertical height and a shortened length from anterior to posterior. Malformations of the occipital region are also often present. [1] [2] [3]
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 ...
Pierre Robin sequence (/ p j ɛər r ɔː ˈ b æ̃ /; abbreviated PRS) is a congenital defect observed in humans which is characterized by facial abnormalities.The three main features are micrognathia (abnormally small mandible), which causes glossoptosis (downwardly displaced or retracted tongue), which in turn causes breathing problems due to obstruction of the upper airway.
