A 16-month-old child presents with hypertelorism, an elongated, flattened forehead, and syndactyly of hands and feet. It is a genetic disorder inherited by birth and the children with this syndrome will have markedly long head and distorted face. Apert syndrome is a genetic disorder that causes abnormal development of the skull. Apert syndrome was originally described as a triad of: 1. craniosynostosis: brachycephaly 2. syndactyly 3. maxillary hypoplasia However, other features may include: 1. tower-shaped head and prominent forehead 2. hypertelorism 3. intellectual retardation (IQ however can be normal) 4. exophthalmos Many syndromes and conditions include abnormalities of both the craniofacial structures and the limbs. Apert syndrome is a severe craniofacial syndrome that was initially described in 1906 by French physician Eugene Apert. Introduction: Apert syndrome is one of the most common craniosynostosis syndrome caused by mutations in genes encoding fibroblast growth factor receptor 2 (FGFR2). 8. The incidence of Apert syndrome in the general population is ~1 in 160,000 live births. CASE 115 Clinical Presentation Most patients demonstrate at least mild prognathism. 2007;27 (7): 629-32.

Box 1184, Fair Oaks, CA 95628, United States The syndrome of Apert or Acrocephalosyndactyly type I (ACS1), is a pathology of genetic origin that is characterized by the presence of different alterations and malformations in the skull, face and limbs (Boston Children’s Hospital, 2016). It is characterized by multisuture craniosynostosis, midfacial hypoplasia, abnormal skull base development and … Can be passed on from the child’s parents through autosomal dominant inheritance - only one parent needs to have the abnormal gene for the child to inherit the disease. Provides information and referrals, newsletter, phone support network, pen pals, and annual family get-togethers. Figure 115C Cranial findings seen in affected infants include a flattened, elongated forehead, turribrachycephaly, hypertelorism, exophthalmos, a bulbous nose, and a flattened nasal bridge. Carpenter syndrome The syndrome can be caused by a random mutation on a gene that produces a fibroblast growth factor receptor 2 (FGR2), located on chromosome 10. Apert syndrome is a somewhat rare condition, occurring in about one of every 65,000 to 160,000 births. Of the specific entities within this grouping, Apert syndrome is the most common.

Cranial findings seen in affected infants include a flattened, elongated forehead, turribrachycephaly, hypertelorism, exophthalmos, a bulbous nose, and a flattened nasal bridge. A 16-month-old child presents with hypertelorism, an elongated, flattened forehead, and syndactyly of hands and feet. Patients with syndactyly, distal limb abnormalities, and craniosynotosis most often suffer from acrocephalosyndactyly. In addition to the abnormal skull such children would also have various other problems inherited by birth. People with Apert syndrome can have distinctive malformations of the skull, face, hands, and feet. Ottavio Piccin, Rossella Sgarzaji, and Paolo G. Morselli for their insightful discussion regarding our recent article, “Airway Analysis in Apert Syndrome.” 1 We agree with the authors about the discrepancies among actual surgical intervention, airway volume measurements, and respiratory outcome. Apert syndrome may be diagnosed prenatally and presents clinically at birth. Disturbances in the development of the branchial arches in fetal development create lasting and widespread effects. Eugène Apert and his contributions to plastic surgery. Close phenotypic mimics are Crouzon syndrome and Pfeiffer syndrome, both of which are also caused by mutations in FGFR2.

Apert syndrome may be diagnosed prenatally and presents clinically at birth. 3. Clinical Findings. Most children who have Apert syndrome have no family history of the condition. The association between syndactyly and craniosynostosis was first described by Apert in 1906. Apert syndrome is a congenital disorder characterized primarily by craniosynostosis, midface hypoplasia, and syndactyly of the hands and feet with a tendency to fusion of bony structures. Close phenotypic mimics are Crouzon syndrome and Pfeiffer syndrome, both of which are also caused by mutations in FGFR2. Check for errors and try again. The orbits show downward slanting. The condition affects males and females in equal numbers. Crouzon syndrome is a rare inherited disorder in which many of the flexible seams (sutures) in a baby’s skull turn to bone and fuse too early. Apert syndrome is a rare genetic condition that is apparent at birth. The anterior fontanelle is widely patent. Skidmore DL, Pai AP, Toi A et-al. Most cases are sporadic, but autosomal dominant inheritance has been reported (Mantilla-Capacho et al., 2005).

Radiology … 115A) demonstrates the characteristic “mitten hand” deformity, with hypoplasia of the first, third, and fourth metacarpals, abnormally short and wide first proximal “delta” phalanx, and symphalangism (i.e., syndactyly/ankylosis of the finger or toe joints) of second through fourth rays, with soft tissue syndactyly of the second through fifth rays. Discussion Apert syndrome may be diagnosed prenatally and presents clinically at birth. This early fusion prevents the skull from growing normally and affects the shape of the head and face. 2. The orbits show downward slanting. Saethre-Chotzen syndrome Fetal. The anterior fontanelle is widely patent. Crouzon syndrome In addition, a varied number of fingers and toes are fused together (syndactyly). Specifically, this syndrome affects the first branchial (or pharyngeal) arch, which is the precursor of the maxilla and mandible.Since the branchial arches are important developmental features in a growing embryo, disturbances in their development create lasting and widespread effects. Thieme. Apert syndrome is primarily characterized by a fusion of the skull bones that occurs too early during development (craniosynostosis) and webbing of the fingers and toes (syndactyly). 115A) demonstrates the characteristic “mitten hand” deformity, with hypoplasia of the first, third, and fourth metacarpals, abnormally short and wide first proximal “delta” phalanx, and symphalangism (i.e., syndactyly/ankylosis of the finger or toe joints) of second through fourth rays, with soft tissue syndactyly of the second through fifth rays. Figure 115B Prenatal diagnosis relies mainly on the association of skull deformity and associated abnormalities that mainly apply to the diagnosis of Apert's syndrome with syndactyly 10-18.

There are many abnormalities which may be visible on imaging including 3: Other more subtle features which may be evident include tower-shaped head and prominent forehead, hypertelorism and exophthalmos. Sunken appearance of the face 2. The Apert syndrome (also known as type I acrocephalosyndactyly) is a syndrome predominantly characterized by skull and limb malformations. Nasopharyngeal obstruction is seen in 50%, due to midface hypoplasia. Abstract In 1906 Apert (2) first called attention to the syndrome of coronal suture synostosis (acrocephaly) and syndactylism. Prenat. The right hand demonstrated an identical appearance. Apert syndrome causes. Apert syndrome is characterized by craniosynostosis and complex hand and foot syndactyly, and an increased risk of brain, palate, heart, and visceral malformations, and intellectual disability. The patients presented with limited joint mobility and were found to have multiple radiographic abnormalities, including subluxated or flattened humeral heads, irregularities of the glenoid cavity, and early fusion of the calcaneus to the cuboid bone. Diagnosis of Apert syndrome in the second-trimester using 2D and 3D ultrasound. The incidence of Apert syndrome in the general population is ~1 in 160,000 live births. Apert syndrome shows autosomal dominant heritance, but nearly all cases result from new gene mutations. The right hand demonstrated an identical appearance. Apert syndrome was originally described as a triad of: Thought to occur from a defect on the fibroblast growth factor receptor 2 (FGFR2) gene, located on chromosome 10q26. 115B, and 115C). Our expert, multidisciplinary team of surgeons has extensive experience treating the full range of conditions related to Apert syndrome. [3, 17] He described the synostosis of cranial sutures and the severe syndactyly of fingers and toes, a condition that he named acrocephalosyndactyly.It is a rare disease, with an estimated incidence of 1/65.000 births. Close phenotypic mimics are Crouzon syndrome and Pfeiffer syndrome, both of which are also caused by mutations in FGFR2. It can be inherited as an autosomal dominant trait, although most cases are thought to be sporadic. Etiology Radiologic Findings Cohen MM Jr, Kreiborg S. The central nervous system in the Apert syndrome. Apert syndrome is a rare genetic disorder that causes a fetus’ facial and skull bones to fuse together too early in its development. Underdevelo… Craniosynostosis. The association between syndactyly and craniosynostosis was first described by Apert in 1906. Babies with Apert syndrome have certain skull bones that fuse together prematurely in utero (before birth) causing a condition known as craniosynostosis.2 This early fusion prevents the skull from growing like it should and affects the shape of the head and face. Entezami M, Albig M, Knoll U et-al. Clinical Findings Diagn. T The early fusion of the skull causes the head to be cone-shaped (acrocephaly). Of the specific entities within this grouping, Apert syndrome is the most common. Amniotic band syndrome Due to the premature fusion, the growth, shape and size of the cranium get affected. 1 article features images from this case Apert syndrome Apert syndrome is characterized by craniosynostosis, a condition in which the fibrous joints (sutures) between bones of … Individuals with Apert syndrome typically have the following conditions: Am J Perinatol. As well as the skull and face, the hands and feet are also affected. Apert syndrome (AS) or acrocephalosyndactyly is a rare autosomal dominant malformation characterized by craniosynostosis, symmetric severe syndactyly, abnormalities of skin, skeleton, brain, and other organs.
