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 .
ACS. Syndactyly in acrocephalosyndactyly (Apert) Specialty. Medical genetics. 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 ...
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.
Hypertelorism can also be seen in Apert syndrome, Autism spectrum disorder, craniofrontonasal dysplasia, Noonan syndrome, neurofibromatosis, LEOPARD syndrome, Crouzon syndrome, Wolf–Hirschhorn syndrome, Andersen–Tawil syndrome, Waardenburg syndrome and cri du chat syndrome, along with piebaldism, prominent inner third of the eyebrows ...
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 ...
Complex syndactyly occurs as part of a syndrome (such as Apert syndrome) and typically involves more digits than simple syndactyly. Fenestrated syndactyly, also known as acrosyndactyly or terminal syndactyly, [2] means the skin is joined for most of the digit but in a proximal area there are gaps in the syndactyly with normal skin.
Apert syndrome: an abnormal skull shape, small upper jaw, and fusion of the fingers and toes. Baller-Gerold syndrome: craniosynostosis with radial aplasia. Beare-Stevenson syndrome: craniosynostosis with cutis gyrata, acanthosis nigricans, and digit anomalies.
Brachymetatarsia is a rare malformation that causes one or more toes to be abnormally short. The condition is characterized by a metatarsal arch shortness of more than 5 mm. The condition is more common in females, and the incidence reported in the literature ranges from 0.02% to 0.05%.
Saethre–Chotzen syndrome (SCS), also known as acrocephalosyndactyly type III, is a rare congenital disorder associated with craniosynostosis (premature closure of one or more of the sutures between the bones of the skull). This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face.
Apert syndrome. Patients with Apert syndrome have a high occurrence of middle ear disease, otitis media and conductive hearing loss (Perterson-Fazone et al., 2001). Conductive hearing loss is frequently seen in this population due to almost constant middle ear disease (Gould et al., 1982).
