Cranial findings seen in affected infants include a flattened, elongated forehead, turribrachycephaly, hypertelorism, exophthalmos, a bulbous nose, and a flattened nasal bridge. Characteristic malformations of the Apert syndrome are early craniostenosis, microviscerocranium and II-V finger syndactyly of hand and toes … 1997;14 (7): 427-30. The incidence of Apert syndrome in the general population is ~1 in 160,000 live births. Sunken appearance of the face 2. The estimated incidence is 1 case per 65-80,000 pregnancies. Of the specific entities within this grouping, Apert syndrome is the most common. Radiograph of the left hand (Fig. [4,5,11,17,18] These syndromes show presence of limb and digital abnormalities, unlike Crouzon syndrome. (2010) Annals of plastic surgery. Molecular analysis of fetal DNA can be used in Apert, Crouzon, Pfeiffer and Jackson–Weiss syndromes 15 - 22 when the family history is informative. Pfeiffer syndrome It is classified as a branchial arch syndrome, affecting the first branchial (or pharyngeal) arch, the precursor of the maxilla and mandible. The association between syndactyly and craniosynostosis was first described by Apert in 1906. 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. What is Apert Syndrome ? Diagn. Radiologic Findings Rubinstein-Taybi syndrome Later reviews have appeared in the medical literature but none in American radiological journals. Patients with syndactyly, distal limb abnormalities, and craniosynotosis most often suffer from acrocephalosyndactyly. 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. Introduction: Apert syndrome is one of the most common craniosynostosis syndrome caused by mutations in genes encoding fibroblast growth factor receptor 2 (FGFR2). Disturbances in the development of the branchial arches in fetal development create lasting and widespread effects. Apert syndrome is a form of acrocephalosyndactyly, a congenital disorder characterized by malformations of the skull, face, hands and feet. Individuals with Apert syndrome typically have the following conditions: 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). Apert syndrome is a genetic disorder characterized by skeletal abnormalities. Scope: International network Founded: 1995 Address: P.O. It is named after Eugene Apert (1868–1940) 7, French pediatrician, who described it in 1906, although some reports suggest it was first described by Wheaton in 1894 2. 4. Apert syndrome is a disorder that is marked by abnormal growth of skull bones. Crouzon syndrome is an autosomal dominant genetic disorder known as a branchial arch syndrome. Prenat. Apert syndrome is a type of complex craniosynostosis named after the doctor who first described it in the early 20th century. Apert syndrome appears to be caused by either of two distinct point mutations in fibroblast growth factor receptor 2 (FGFR2). 7. Apert syndrome: the current role of prenatal ultrasound and genetic analysis in diagnosis and counselling. Babies with Apert syndrome are born with a distorted shape of the head and face. A key feature of Apert syndrome is the premature closure of the bones of the skull (craniosynostosis). Kaufmann K, Baldinger S, Pratt L. Ultrasound detection of Apert syndrome: a case report and literature review. Provides information and referrals, newsletter, phone support network, pen pals, and annual family get-togethers. Clinical Findings [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. 2. Box 1184, Fair Oaks, CA 95628, United States A 16-month-old child presents with hypertelorism, an elongated, flattened forehead, and syndactyly of hands and feet. Apert syndrome appears to be caused by either of two distinct point mutations in fibroblast growth factor receptor 2 (FGFR2). Nasopharyngeal obstruction is seen in 50%, due to midface hypoplasia. INTRODUCTION: Apert syndrome is one of the most common craniosynostosis syndrome caused by mutations in genes encoding fibroblast growth factor receptor 2 (FGFR2). Many syndromes and conditions include abnormalities of both the craniofacial structures and the limbs. The anterior fontanelle is widely patent. Isolated familial syndactyly syndromes Apert syndrome, also called acrocephalosyndactyly, is a genetic syndrome characterized by anomalies of the skull, face and limbs. Kreiborg S, Barr M Jr, Cohen MM Jr. Cervical spine in the Apert syndrome. 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. The association between syndactyly and craniosynostosis was first described by Apert in 1906. Most patients demonstrate at least mild prognathism. 3. Abstract In 1906 Apert (2) first called attention to the syndrome of coronal suture synostosis (acrocephaly) and syndactylism. Am J Perinatol. 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. Of the specific entities within this grouping, Apert syndrome is the most common. Our expert, multidisciplinary team of surgeons has extensive experience treating the full range of conditions related to Apert syndrome. Close phenotypic mimics are Crouzon syndrome and Pfeiffer syndrome, both of which are also caused by mutations in FGFR2. It is a genetic disorder inherited by birth and the children with this syndrome will have markedly long head and distorted face. Nasopharyngeal obstruction is seen in 50%, due to midface hypoplasia. The condition affects males and females in equal numbers. Check for errors and try again. [3,17] He described the synostosis of cranial sutures and the severe syndactyly of fingers and toes, a condition that he named acrocephalosyndactyly. Etiology Ultrasound Diagnosis of Fetal Anomalies. Diagnosis Due to the premature fusion, the growth, shape and size of the cranium get affected. Am J Med Genet 1992; 43 (4): 704-708. As well as the skull and face, the hands and feet are also affected. 115B, and 115C). The Apert syndrome (also known as type I acrocephalosyndactyly) is a syndrome predominantly characterized by skull and limb malformations. 64 (3): 362-5. The anterior fontanelle is widely patent. Close phenotypic mimics are Crouzon syndrome and Pfeiffer syndrome, both of which are also caused by mutations in FGFR2. Bulging and/or wide-set eyes 3. People with Apert syndrome can have distinctive malformations of the skull, face, hands, and feet. Apert syndrome is caused by a mutation in the fibroblast growth factor receptor 2 (FGFR2) gene. 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. {"url":"/signup-modal-props.json?lang=us\u0026email="}. Clinical Findings. Figure 115B AJNR Am J Neuroradiol. Prenat. The orbits show downward slanting. 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. Apert syndrome is characterized by craniosynostosis, a condition in which the fibrous joints (sutures) between bones of … There is synostosis of the coronal sutures, hypertelorism, and flattening and downward slanting of the shallow bony orbits (Figs. Figure 115A Most children who have Apert syndrome have no family history of the condition. Apert syndrome may be diagnosed prenatally and presents clinically at birth. 7. T The early fusion of the skull causes the head to be cone-shaped (acrocephaly). 1. Apert syndrome is a rare autosomal dominant disorder characterized by craniosynostosis, craniofacial anomalies, and severe symmetrical syndactyly (cutaneous and bony fusion) of … Diagn. Diagn. Apert syndrome is a severe craniofacial syndrome that was initially described in 1906 by French physician Eugene Apert. Apert syndrome is a rare genetic disorder that causes a fetus’ facial and skull bones to fuse together too early in its development. 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). 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. Carpenter syndrome Robson CD, Mulliken JB, Robertson RL et-al. David AL, Turnbull C, Scott R et-al. Apert syndrome (acrocephalosyndactyly type 1) Its typical characteristic is a premature fusion of the skull bones, which prevents the skull from growing normally leading to … Cranial findings seen in affected infants include a flattened, elongated forehead, turribrachycephaly, hypertelorism, exophthalmos, a bulbous nose, and a flattened nasal bridge. Apert syndrome is a genetic disorder that causes abnormal development of the skull. Amniotic band syndrome Ther. 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 8. Lee DS, Chung KC. 2003;23 (12): 1009-13. Radiograph of the left hand (Fig. Figure 115C Apert syndrome is a rare genetic birth disorder that causes the bones in an infant’s head, face, hands and feet to close (fuse) together abnormally. Differential Diagnosis It is characterized by multisuture craniosynostosis, midfacial hypoplasia, abnormal skull base development and … In addition, a varied number of fingers and toes are fused together (syndactyly). 2008;24 (4): 495-8. Apert syndrome (also known as type I acrocephalosyndactyly) is a syndrome that is predominantly characterized by skull and limb malformations. Most patients demonstrate at least mild prognathism. The right hand demonstrated an identical appearance. Clinical Radiology 2002; 57: 93-102. Collapse Section. Apert Syndrome is a genetic condition resulting from a mutation in gene FGRF2 – fibroblast growth factor receptor 2 – on chromosome 10. There is synostosis of the coronal sutures, hypertelorism, and flattening and downward slanting of the shallow bony orbits (Figs. Craniosynostosis. 1 article features images from this case Apert syndrome The condition of Apert syndrome arises due to a genetic disorder which leads to the premature fusion of cranial bones in the skull. The condition also leads to the fusion of … Discussion Apert syndrome causes facial and skull abnormalities, … This early fusion prevents the skull from growing normally and affects the shape of the head and face. 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. 5. 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. Background This study aims to describe the structural brain abnormalities detected by dedicated neuroimaging of fetuses with Apert syndrome. Apert syndrome may be diagnosed prenatally and presents clinically at birth. Apert syndrome - acrocephalosyndactyly - is a rare autosomal dominant disorder representing 1:65 000 cases of living newborns. Crouzon syndrome Unable to process the form. Apert syndrome is a somewhat rare condition, occurring in about one of every 65,000 to 160,000 births. 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. Most cases are sporadic, but autosomal dominant inheritance has been reported (Mantilla-Capacho et al., 2005). Beaked nose 4. Apert syndrome shows autosomal dominant heritance, but nearly all cases result from new gene mutations. 2000;21 (9): 1707-17. Am J Med Genet 1990; 35 (1):36-45. 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. 2007;27 (7): 629-32. Cohen MM Jr, Kreiborg S. The central nervous system in the Apert syndrome. 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. Apert syndrome appears to be caused by either of two distinct point mutations in fibroblast growth factor receptor 2 (FGFR2). Clinical Presentation Prominent basal emissary foramina in syndromic craniosynostosis: correlation with phenotypic and molecular diagnoses. This page from Great Ormond Street Hospital (GOSH) explains the causes, symptoms and treatment of Apert syndrome.

Most cases of Apert syndrome result from a new mutation, rather than being genetically inherited from a parent. 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. In addition to the abnormal skull such children would also have various other problems inherited by birth. Sir: We would like to thank Drs. Apert syndrome is a rare genetic condition that is apparent at birth. 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. Fetal. It can be inherited as an autosomal dominant trait, although most cases are thought to be sporadic. Diagnosis of Apert syndrome in the second-trimester using 2D and 3D ultrasound.
