Most persons with Pfeiffer syndrome type 1 have a normal intelligence and life span; types 2 and 3 typically cause neurodevelopmental disorders and early death. Later in life, surgery can help in bone formation and facial construction. Pfeiffer syndrome affects about 1 in 100,000 persons.
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.
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 ...
Infectious mononucleosis ( IM, mono ), also known as glandular fever, is an infection usually caused by the Epstein–Barr virus (EBV). [2] [3] Most people are infected by the virus as children, when the disease produces few or no symptoms. [2] In young adults, the disease often results in fever, sore throat, enlarged lymph nodes in the neck ...
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.
Carpenter syndrome has an autosomal recessive pattern of inheritance. Carpenter syndrome has been associated with mutations in the RAB23 gene, which is located on chromosome 6 in humans. Additionally, three key SNPs in the MEGF8 gene, located on chromosome 19 at 19q13.2, have been identified as primary causes of Carpenter syndrome. Diagnosis
Apert syndrome is a form of acrocephalosyndactyly, a congenital disorder characterized by malformations of the skull, face, hands and feet. It is classified as a branchial arch syndrome, affecting the first branchial (or pharyngeal) arch, the precursor of the maxilla and mandible. Disturbances in the development of the branchial arches in fetal ...
Differential diagnosis: Loeys-Dietz syndrome, Ehlers-Danlos syndrome: Medication: Beta blockers, calcium channel blockers, ACE inhibitors: Prognosis: Often normal life expectancy: Frequency: 1 in 5,000–10,000
A conductive hearing loss along with middle ear disease is most commonly seen in patients with Pfeiffer syndrome; although, there have been reports of mixed hearing loss as well. The hearing loss is most typically caused by stenosis or atresia of the auditory canal , middle ear hypoplasia and ossicular hypoplasia (Vallino-Napoli, 1996).
Also any condition that causes significant depression of the nasal bridge or midface retraction can be associated with choanal atresia. Examples include the craniosynostosis syndromes such as Crouzon syndrome, [1] Pfeiffer syndrome, [1] Treacher Collins syndrome, [1] Apert syndrome, [1] and Antley-Bixler syndrome .
