Family study of inherited syndrome with multiple congenital deformities: symphalangism, carpal and tarsal fusion, brachydactyly, craniosynostosis, strabismus, hip osteochondritis. (1/270)

A syndrome of brachydactyly (absence of some middle or distal phalanges), aplastic or hypoplastic nails, symphalangism (ankylois of proximal interphalangeal joints), synostosis of some carpal and tarsal bones, craniosynostosis, and dysplastic hip joints is reported in five members of an Italian family. It may represent a previously undescribed autosomal dominant trait.  (+info)

A novel skeletal dysplasia with developmental delay and acanthosis nigricans is caused by a Lys650Met mutation in the fibroblast growth factor receptor 3 gene. (2/270)

We have identified a novel fibroblast growth factor receptor 3 (FGFR3) missense mutation in four unrelated individuals with skeletal dysplasia that approaches the severity observed in thanatophoric dysplasia type I (TD1). However, three of the four individuals developed extensive areas of acanthosis nigricans beginning in early childhood, suffer from severe neurological impairments, and have survived past infancy without prolonged life-support measures. The FGFR3 mutation (A1949T: Lys650Met) occurs at the nucleotide adjacent to the TD type II (TD2) mutation (A1948G: Lys650Glu) and results in a different amino acid substitution at a highly conserved codon in the kinase domain activation loop. Transient transfection studies with FGFR3 mutant constructs show that the Lys650Met mutation causes a dramatic increase in constitutive receptor kinase activity, approximately three times greater than that observed with the Lys650Glu mutation. We refer to the phenotype caused by the Lys650Met mutation as "severe achondroplasia with developmental delay and acanthosis nigricans" (SADDAN) because it differs significantly from the phenotypes of other known FGFR3 mutations.  (+info)

Non-invasive aortic blood flow measurement in infants during repair of craniosynostosis. (3/270)

We have assessed the potential clinical benefit of a new echo-Doppler device (Dynemo 3000) which provides a continuous measure of aortic blood flow (ABF) using an aortic flowmeter and a paediatric oesophageal probe, during repair of craniosynostosis in infants under general anaesthesia. The data recorded included: ABFi (i = indexed to body surface area), stroke volume (SVi), systemic vascular resistance (TSVRi), pre-ejection period (PEP), left ventricular ejection time (LVET), mean arterial pressure (MAP), heart rate (HR) and central venous pressure (CVP). Data were collected: before (T1) and 3 min after skin incision (T2), at the time of maximal haemorrhage (T3) and at the end of the procedure (T4). Twelve infants (aged 7.0 (range 6-12) months) were included. ABFi, MAP and CVP were significantly lower at T3 compared with T1 (2.0 (0.8) vs 3.0 (0.8) litre min-1 m-2, 46.1 (5.8) vs 65.2 (8.9) mm Hg and 2.8 (1.6) vs 5.2 (2.1) mm Hg; P < 0.05). PEP/LVET ratio was significantly lower at T2 compared with T1 (0.25 (0.05) vs 0.30 (0.06)) and increased at T4 (0.36 (0.04); P < 0.05). These preliminary results suggest that this non-invasive ABF echo-Doppler device may be useful for continuous haemodynamic monitoring during a surgical procedure associated with haemorrhage in infants.  (+info)

Decreased proliferation and altered differentiation in osteoblasts from genetically and clinically distinct craniosynostotic disorders. (4/270)

Craniosynostoses are a heterogeneous group of disorders characterized by premature fusion of cranial sutures. Mutations in fibroblast growth factor receptors (FGFRs) have been associated with a number of such conditions. Nevertheless, the cellular mechanism(s) involved remain unknown. We analyzed cell proliferation and differentiation in osteoblasts obtained from patients with three genetically and clinically distinct craniosynostoses: Pfeiffer syndrome carrying the FGFR2 C342R substitution, Apert syndrome with FGFR2 P253R change, and a nonsyndromic craniosynostosis without FGFR canonic mutations, as compared with control osteoblasts. Osteoblasts from craniosynostotic patients exhibited a lower proliferation rate than control osteoblasts. P253R and nonsyndromic craniosynostosis osteoblasts showed a marked differentiated phenotype, characterized by high alkaline phosphatase activity, increased mineralization and expression of noncollagenous matrix proteins, associated with high expression and activation of protein kinase Calpha and protein kinase Cepsilon isoenzymes. By contrast, the low proliferation rate of C342R osteoblasts was not associated with a differentiated phenotype. Although they showed higher alkaline phosphatase activity than control, C342R osteoblasts failed to mineralize and expressed low levels of osteopontin and osteonectin and high protein kinase Czeta levels. Stimulation of proliferation and inhibition of differentiation were observed in all cultures on FGF2 treatment. Our results suggest that an anticipated proliferative/differentiative switch, associated with alterations of the FGFR transduction pathways, could be the causative common feature in craniosynostosis and that mutations in distinct FGFR2 domains are associated with an in vitro heterogeneous differentiative phenotype.  (+info)

Fetal craniofacial structure and intracranial morphology in a case of Apert syndrome. (5/270)

Apert syndrome is characterized by craniosynostosis, midfacial hypoplasia and bilateral syndactyly. We document in detail the intrauterine natural history of Apert syndrome by serial sonographic examination. Ultrasound examination of a 19-week fetus revealed an abnormal appearance of the skull. The subsequent examination including transvaginal brain scanning demonstrated a deformed occipital part of the cerebrum and lateral ventricles, frontal bossing, a low nasal bridge and an abnormal appearance of the fetal hands and feet. The distortion of the fetal profile became progressively worse with advancing gestation. Towards the end of pregnancy, anterior prominence of the cerebrum, ventricles and corpus callosum was demonstrated and mild non-progressive ventriculomegaly was seen. The female 3152-g newborn with the typical facial appearance of Apert syndrome, bilateral syndactyly of the fingers and toes and isolated cleft palate was delivered at 37 weeks. Postnatal three-dimensional computed tomography scan demonstrated the fusion of the coronal suture and a wide mid-line calvarial defect, and cranial magnetic resonance imaging confirmed the prenatal sonographic findings. Although the karyotype was normal, genomic DNA analysis of the fibroblast growth factor receptor 2 revealed Ser252Trp, which is specified in the mutational basis of Apert syndrome. The time course of the prenatal findings in this case may help increase understanding of the intrauterine natural history of Apert syndrome.  (+info)

Reduction of operating time and blood transfusion for craniosynostosis by simulated surgery using three-dimensional solid models. (6/270)

Preoperative planning of craniofacial synostosis can be achieved through the use of two- or three-dimensional (3D) computed tomography (CT) images and by 3D solid models. The advantage of using 3D models was evaluated by calculating the amount of blood transfused and the operating time for 36 craniosynostosis procedures, 21 planned with 3D models and 15 with CT images performed in the past 7 years. The use of 3D models reduced both blood loss and operating time for fronto-orbital advancement with reshaping, LeFort III advancement, and LeFort IV minus Glabellar advancement; blood loss for fronto-orbital advancement without reshaping; and operating time for total cranial reshaping.  (+info)

Three-dimensional morphological analysis of isolated metopic synostosis. (7/270)

Morphological differences were quantified in three-dimensions among individuals with untreated isolated metopic synostosis and between those individuals and similar aged-matched normal dry skulls to test two hypotheses: first, that the dysmorphology is a self-correcting condition; and second, that a lack of vertical growth of the skull produces this dysmorphology. Three-dimensional (3D) coordinates were recorded for 22 craniofacial landmarks from CT scans of 15 metopic patients, ranging from 5- to 32-months-old, and of four normal dry skulls, ranging in age from 6- to 36-months-old. The patient population was diagnosed with isolated metopic synostosis at The Johns Hopkins Medical Institutions in Baltimore, Maryland or Children's Hospital in St. Louis, Missouri. Comparisons between the metopic age groups indicate that the trigonocephalic phenotype worsens through time. Between 5 and 14 months, the neurocranium displays an increase in vertical growth. This was followed by a lack of vertical growth between 14 and 32 months. The face displays a lack of vertical growth from 5 to 14 months and an increase in vertical growth after 14 months. Comparisons between the metopic age groups and the normal skulls indicate that the trigonocephalic head is taller superoinferiorly and longer anteroposteriorly. Relative to the normal phenotype, the inferior temporal region in the metopic phenotype is narrow. These findings enabled the rejection of both hypotheses and localized form differences between normal and metopic phenotypes. Based on these results, we suggest that the trigonocephalic phenotype worsens with age and the amount of vertical growth that produces the trigonocephalic phenotype varies throughout growth with respect to location within the skull and age.  (+info)

Evidence for digenic inheritance in some cases of Antley-Bixler syndrome? (8/270)

The Antley-Bixler syndrome has been thought to be caused by an autosomal recessive gene. However, patients with this phenotype have been reported with a new dominant mutation at the FGFR2 locus as well as in the offspring of mothers taking the antifungal agent fluconazole during early pregnancy. In addition to the craniosynostosis and joint ankylosis which are the clinical hallmarks of the condition, many patients, especially females, have genital abnormalities. We now report abnormalities of steroid biogenesis in seven of 16 patients with an Antley-Bixler phenotype. Additionally, we identify FGFR2 mutations in seven of these 16 patients, including one patient with abnormal steroidogenesis. These findings, suggesting that some cases of Antley-Bixler syndrome are the outcome of two distinct genetic events, allow a hypothesis to be formulated under which we may explain all the differing and seemingly contradictory circumstances in which the Antley-Bixler phenotype has been recognised.  (+info)

Sagittal synostosis is a condition in infants where the sagittal suture (the soft spot or fontanelle on top of the head between the left and right sides of the skull) closes early and inhibits growth of the head in the side to side direction. This forces the head to grow in a front to back direction, leading to a narrow elongated head.

Recently, the molecular bases of these classical disorders, a new common craniosynostosis syndrome (Muenke syndrome (MIM 134934)), and several of the rare craniosynostosis syndromes have been identified. Pfeiffer syndrome is heterogeneous and due to heterozygous mutations in fibroblast growth factor receptor (FGFR) genes 1 and 2. Heterozygous mutations in FGFR2 also cause Apert, Crouzon, Jackson-Weiss (MIM 123150), and Beare-Stevenson (MIM 123790) syndromes. Muenke syndrome was newly defined by a specific mutation in FGFR3, which corresponds to an amino acid substitution equivalent to one change in Apert syndrome in FGFR2 and in Pfeiffer syndrome in FGFR1. Crouzon syndrome with acanthosis nigricans is due to a mutation in FGFR3. Cytogenetic deletions and translocations involving 7p21.1 and various heterozygous mutations in the human/mouse gene symbols for a transcription factor originally named in Drosophila. (TWIST) gene, which maps to this region, cause Saethre-Chotzen syndrome. A missense ...
UniProtKB/Swiss-Prot : 71 Muenke syndrome: A condition characterized by premature closure of coronal suture of skull during development (coronal craniosynostosis), which affects the shape of the head and face. It may be uni- or bilateral. When bilateral, it is characterized by a skull with a small antero- posterior diameter (brachycephaly), often with a decrease in the depth of the orbits and hypoplasia of the maxillae. Unilateral closure of the coronal sutures leads to flattening of the orbit on the involved side (plagiocephaly). The intellect is normal. In addition to coronal craniosynostosis some affected individuals show skeletal abnormalities of hands and feet, sensorineural hearing loss, mental retardation and respiratory insufficiency ...

BACKGROUND: Posterior advancement of the occiput is an established surgical option for the treatment of raised intracranial pressure (ICP) secondary to craniocerebral disproportion in syndromic craniosynostoses. Distraction osteogenesis has gained popularity in a variety of craniofacial procedures to achieve greater advancement in the anterior craniofacial skeleton, but has only relatively recently been used in the posterior calvarium. We report the Oxford Craniofacial Units experience of using distraction techniques to expand the occiput. METHODS: We preformed a retrospective casenote review of all patients with syndromic craniosynostoses who underwent posterior distraction at our centre from 2007 to 2010, as identified by the Oxford Craniofacial Database. RESULTS: Ten syndromic patients underwent posterior distraction (mean age of 18.1 months). Successful calvarial expansion (mean advancement of 19.7 mm) was achieved in all patients clinically and radiologically. There were 6 minor and 1 major
Objective: to investigate visual function pre- and post surgery in children with single-suture non-syndromic craniosynostosis. Design: Twenty-nine infants (12 with sagittal synostosis, 10 with trigonocephaly and 7 with anterior plagiocephaly) were longitudinally evaluated using a battery of tests assessing various aspects of visual function, including ocular behaviour, acuity, visual fields and fixation shift. All infants were assessed before surgery and 2, 6 and 12 months after surgery.. Results: Before surgery only 16% of infants had completely normal visual function, while on the assessment performed 12 months after surgery, the number with normal results on all the tests increased to 65%. The only abnormalities found 12 months after surgical correction were mainly found on abnormal oculomotor behaviour in infants with plagiocephaly.. Conclusion: Abnormalities of visual function were not frequent in infants with non-syndromic craniosynostosis who underwent surgical correction. Approximately ...
FGFR2 related craniosynostosis - The craniosynostosis syndromes are a group of disorders sharing the premature fusion of one or more sutures of the skull. Often additional anomalies are associated. There are sixcraniosynostosis disorders caused by mutations in the fibroblast growth factor receptor 2 gene (FGFR2). They include Apert syndrome (MIM 101200), Beare-Stevenson cutis gyrata syndrome (BSTVS; MIM 123790), Crouzon syndrome (MIM 123500), Jackson-Weiss syndrome (JWS; MIM123150), Pfeiffer syndrome (MIM 101600) and FGFR2 related isolated coronal synostosis. All are autosomal dominant. Penetrance varies with the specific craniosynostosis type. Many FGFR2 mutations are associated with advanced paternal age.. Read less ...

Long-term anthropometric follow-up of cranial vault growth may considerably add valuable information to current literature focusing on treatment strategies for premature multiple-suture craniosynostosis. The aim of this paper was to compare postoperative growth patterns of nonsyndromic and syndromic multiple-suture craniosynostotic children with sex-matched and age-matched children from the typically developing population. Forty-one multiple-suture craniosynostotic patients (19 nonsyndromic and 22 syndromic) were included in this 5-year follow-up. Anthropological data of sex-matched and age-matched normal Swiss children served as a control. A standardized time protocol for anthropometric skull measurements (head circumference and cephalic index) was used. Data were converted into Z-scores for standardized intercenter comparison. All patients showed a marked benefit in cranial vault shape after open skull remodeling. Significant differences in long-term cranial vault growth pattern could be seen ...

We advise parents to treat coronal synostosis before their baby is six months old. That way our doctors can use a minimally invasive procedure to remedy it.
Craniosynostosis is a congenital malformation characterized by premature closure of cranial sutures. The premature closure of the cranial sutures hinders the growth of the skull, brains and face. Craniosynostosis is 1 in 2500 newborns and is for approximately 40% of patients a part of a syndrome such as Apert syndrome, Crouzon / Pfeiffer, Saethre-Chotzen and Muenke. The treatment of syndromic or complex craniosynostosis craniofacial comprises a correction within the first year of life. Depending on the syndrome, multiple corrections of the skull, face hands and feet occur. Besides the appearance, the skull abnormality, hand and foot abnormalities, and brain abnormalities may occur. These brain abnormalities can be congenital, such as abnormalities of the corpus callosum or acquired, such as hydrocephalus ...

Helmet use recommended: The use of helmets postoperatively in children who have had minimally invasive surgery may be considered an adjuvant therapy. Many centers doing a large number of minimally invasive cases use postoperative helmets. However, other centers do not. There are no prospective studies. Small case reports have been published on outcomes without the use of helmets (70, 71). The author advocates using a helmet out of concern that without their use the same cosmetic results seen after open strip craniectomy will occur. Larger, longitudinal studies on surgeries without the subsquent use of helmets are needed ...
Craniosynostosis (from cranio, cranium; + syn, together; + ostosis relating to bone) is a condition in which one or more of the fibrous sutures in an infant (very young) skull prematurely fuses by turning into bone (ossification), thereby changing the growth pattern of the skull. Because the skull cannot expand perpendicular to the fused suture, it compensates by growing more in the direction parallel to the closed sutures. Sometimes the resulting growth pattern provides the necessary space for the growing brain, but results in an abnormal head shape and abnormal facial features. In cases in which the compensation does not effectively provide enough space for the growing brain, craniosynostosis results in increased intracranial pressure leading possibly to visual impairment, sleeping impairment, eating difficulties, or an impairment of mental development combined with a significant reduction in IQ. Craniosynostosis occurs in one in 2000 births. Craniosynostosis is part of a syndrome in 15 to 40% ...

The brain and skull represent a complex arrangement of integrated anatomical structures composed of various cell and tissue types that maintain structural and functional association throughout development. Morphological integration, a concept developed in vertebrate morphology and evolutionary biology, describes the coordinated variation of functionally and developmentally related traits of organisms. Syndromic craniosynostosis is characterized by distinctive changes in skull morphology and perceptible, though less well studied, changes in brain structure and morphology. Using mouse models for craniosynostosis conditions, our group has precisely defined how unique craniosynostosis causing mutations in fibroblast growth factor receptors affect brain and skull morphology and dysgenesis involving coordinated tissue-specific effects of these mutations. Here we examine integration of brain and skull in two mouse models for craniosynostosis: one carrying the FGFR2c C342Y mutation associated with Pfeiffer and

Craniosynostosis is caused by premature closure of the cranial sutures and an associated growth arrest perpendicular to the involved suture line, resulting in a skull deformity that progresses over time until growth is completed. It is therefore important that this issue be surgically addressed early in infancy. It may be part of the previously noted syndromic paradigm, which is associated with brachydactyly (foreshortened extremities), syndactyly (fusion of the phalanges and obliteration of the natural web spaces), and polydactyly (extra digits). There is a great deal of overlap of phenotypic expression among these subtypes. Craniosynostosis may be caused by a new mutation or display either an autosomal dominant or recessive genetic pattern of inheritance. There is evidence of defects in fibroblast growth factor regions (FGFR) of the genome, resulting in abnormal bridging ossification of mesenchymal tissue. ...
34 1. In the world of the craniosynos- toses, one of the most exciting advances in molecular biology and genetics is the levothyroxine and depakote covery of the role of the fibroblast growth factors (FGFs) and fibroblast growth factor receptors (FGFRs) in furthering the under- standing of skeletal dysplasias such as the craniosynostoses (Malcolm and Reardon, 1996; Gorlin, Levothyroxine and depakote.
Dr. Goodrich responded: Craniosynostosis. Craniosynostosis is ideally treated in infancy but having said that our center has done a number of untreated adults or adults whose original surgery did not come out well. A consultation with a craniofacial center with multiple sub-specialities that deal with these disorders would be a good place to start.
November 19, 2012 /Press Release/ -- Researchers at Mount Sinai School of Medicine have validated new genetic links for sagittal craniosynostosis, a common birth defect in which the bones that form the sides and top of the skull, fuse prematurely. The genome-wide association (GWA) study and replication, published online November 18th in the journal Nature Genetics, provides the first strong evidence of genetic variants contributing to non-syndromic sagittal craniosynostosis.. Craniosynostosis is one of the ten most common birth defects, occurring in about 1 out of every 2,500 live births. The sagittal form of craniosynostosis, which impedes growth of the skull so that the shape becomes elongated, occurs in about half the cases, or 1 in 5,000 live births. Unless it is treated surgically to release pressure on the brain within the first year of life, it interferes with brain growth causing neurologic deficits. Non-syndromic sagittal craniosynostosis is not associated with other ...

Craniosynostosis is the premature fusion of cranial bones. The goal of this study was to determine if delivery of recombinant tissue nonspecific alkaline phosphatase (TNAP) could prevent or diminish the severity of craniosynostosis in a C57BL/6 FGFR2C342Y/+ model of neonatal onset craniosynostosis or a BALB/c FGFR2C342Y/+ model of postnatal onset craniosynostosis. Mice were injected with a lentivirus encoding a mineral targeted form of TNAP immediately after birth. Cranial bone fusion as well as cranial bone volume, mineral content and density were assessed by micro computed tomography. Craniofacial shape was measured with calipers., Alkaline phosphatase, alanine amino transferase (ALT) and aspartate amino transferase (AST) activity levels were measured in serum. Neonatal delivery of TNAP diminished craniosynostosis severity from 94% suture obliteration in vehicle treated mice to 67% suture obliteration in treated mice, p,0.02) and the incidence of malocclusion from 82.4% to 34.7% (p,0.03), with ...
In their 2008 series, Marucci and colleagues reviewed 89 patients with isolated sagittal synostosis treated with strip craniectomy. Their patients had the surgical procedure between 5-7 months of age. None of the children had helmet therapy after their procedure as is commonly done after similar procedures here in the United States. Seven of their patients developed a prominent vertex bulge in the months following surgery. All seven of these patients were re-imaged with MRI after the bulge was noted. In 5 patients, there was evidence for elevated intracranial pressure by exam or by MRI, and formal intracranial pressure measurements were done. Pressure was elevated in 4 of these patients. Three patients with elevated pressure and 2 with normal pressure were also found to have fusion of additional cranial sutures on the MRI scans. Genetic testing was done in all children with a vertex bulge, and abnormalities in the fibroblast growth factor receptor gene were found in 2 patients, both of whom also ...
A babys head, or skull, is made up of many different bones. The connections between these bones are called sutures. When a baby is born, it is normal for these sutures to be open a little. This gives the babys brain room to grow.. Craniosynostosis is a condition that causes one or more of the babys sutures to close too early. This can cause the shape of your babys head to be different than normal.. An x-ray or computed tomography (CT) scan can be used to diagnose craniosynostosis. Surgery is usually needed to correct it.. Surgery frees the sutures that are fused. It also reshapes the brow, eye sockets, and skull as needed. The goals of surgery are:. ...

In the study, scientists investigated the role of the Axin2 gene in bone formation and regeneration. They also examined a specific mutation that causes craniosynostosis in mice. Their finding show that stem cells involved in skull formation are contained within this cell population. These cells are specificto the bones in the head and are very different from other stem cells involved in the formation of the bones in the legs and other parts of the body.. Tests to uncover these cells could also help physicians detect bone diseases caused by stem cell abnormalities, according to the researchers.. The research was published Feb. 1 in the journal Nature Communications.. ...

Results A total of 117 patients were identified to have received surgical treatment of craniosynostosis at CHLA between 1995 and 2005. 66 charts contained appropriate data for collection, including a pre-operative head circumference measurement and post-operative head circumference measurements immediately post-operatively, at approximately 3 months, 6 months, and/or 1 year. Of these, 39 patients had sagittal craniosynostosis, 12 coronal, 4 bicoronal, 3 metopic, 3 lambdoid, and 5 multisynostotic. Preliminary results show a progression of head circumference growth along the growth curve at an age appropriate head circumference percentile following surgical treatment of craniosynostosis. Further investigation is pending. ...
At 11:26 am, Dr. Cambrin had just finished talking with us for a couple minutes. It seemed like a really long last hour, thats for sure. He said everything went really well, she woke up fine from the anesthesia, and was being moved to the PICU (pediatric intensive care unit). He had wanted to do more work on the back, but he said, "It was becoming too much of a surgery for her." He thought he might want to do a blood transfusion, but the anesthesiologist didnt, so they would wait and see what the PICU said. Its funny, because he didnt think she needed to go to the PICU, but the anesthesiologist did. Im SO glad she ended up there. They wanted to keep her overnight! The main reasons they wanted to have her there was to control the swelling with the drain in her head so that so much pressure didnt build up and cause brain damage, and also because she was so little, that they needed to really monitor her pain meds so she didnt stop breathing. So, at 12:00 pm, we got to go to the PICU and see ...

The sagittal suture is located on the midline, on top of the skull and extends from the soft spot towards the back of the head. Sagittal suture synostosis is the most common type of single suture synostosis and predominantly affects males. The suture is located at the midline, on top of the skull and extends from the soft spot towards the back of the head. Sagittal synostosis causes a shape thats long and narrow, known as scaphocephaly. As the head grows in this long and narrow direction, the back of the head becomes prominent, pointed and the forehead protrudes. There is a low risk of abnormal brain growth and development. This form of synostosis is generally easy to diagnose.. ...
Muenke syndrome is a condition characterized by the premature closure of certain bones of the skull (craniosynostosis) during development, which affects the shape of the head and face.. Many people with this disorder have a premature fusion of skull bones along the coronal suture, the growth line that goes over the head from ear to ear. Other parts of the skull may also be malformed. These changes can result in an abnormally shaped head, wide-set eyes, and flattened cheekbones. About 5 percent of affected individuals have an enlarged head (macrocephaly). People with Muenke syndrome may also have mild abnormalities of the hands or feet, and hearing loss has been observed in some cases. Most people with this condition have normal intellect, but developmental delay and learning problems are possible.. The signs and symptoms of Muenke syndrome vary among affected people, and some features overlap with those seen in other craniosynostosis syndromes. A small percentage of people with the gene mutation ...
The head circumference should be measured and plotted. This is usually done at the end of the exam because babies usually resent the restriction of head movement necessary to obtain an accurate measurement. Head shape should be noted and the sutures palpated.. Craniosynostosis (premature closure of the suture) can cause a misshaped head. Bone growth occurs perpendicular to the suture. If one suture is closed, compensatory growth will occur in the remaining open sutures. Synostosis of the sagittal suture (the most common type of synostosis) results in scaphocephaly (a thin elongated head). Synostosis of the coronal sutures results in brachycephaly (a wide flat head). Synostosis of the metopic suture results in trigonocephaly (a triangular shaped head).. The most common cause of a misshapen head is flattening of the occipit on one side and is not from lambdoid synostosis but is positional in nature (caused from the baby lying supine with the head turned to one side as a preferred position).. It is ...
Several hypotheses have been proposed to explain a familial disease that caused the bizarre appearance of the royalty, including Marfan syndrome, Wilson-Turner X-linked mental retardation syndrome, Fröhlich syndrome (adiposogenital dystrophy), Klinefelter syndrome, androgen insensitivity syndrome,1 myotonic dystrophy,2 and aromatase excess syndrome in conjunction with sagittal craniosynostosis syndrome, or Antley-Bixler syndrome.3 Hawass and co-workers published results of their molecular genetic studies on mummified remains of the royal family of the 18th dynasty to determine any pathologies and familial disease that might have afflicted them.4 Tests showed no sign of craniosynostoses and Antley-Bixler or Marfan syndrome, and could find no evidence of gynaecomastia because the anterior chest wall of the mummies was not available. Therefore, the presence or absence of gynaecomastia is not clear. The feminised appearance of Akhenaten was excluded by the pelvic bone shape. The study group also ...
CRANIOSYNOSTOSIS. Craniosynostosis is a birth defect of the Skull (which may affect the Brain) that is characterized by the premature closure of one or more of the fibrous joints between the bones of the Skull (called the cranial sutures) before Brain growth is complete. While the premature fusion of the cranial sutures results in disproportionate growth of the cranial bones, it may also affect the growth of the facial bones. When a suture is fused there is no growth in a plain perpendicular to the line of the suture. The abnormally shaped Skull that results is due to the Brain not being able to grow in its natural shape because of the closure. Instead it compensates with growth in areas of the Skull where the cranial sutures have not yet closed.. The Skull has two different components, the first of which forms the "vault" of the Cranium and is called the "membranous" part. The other portion, the "chondrocranium" forms the Base of the Skull. After a certain age there is little likelihood of ...

Jackson-Weiss syndrome is an autosomal dominant condition characterized by craniosynostosis, foot anomalies and great phenotypic variability. Recently mutations in fibroblast growth factor receptor 2 (FGFR2) have been found in patients with another craniosynostotic syndrome, Crouzon syndrome. FGFR2 is a member of the tyrosine kinase receptor superfamily, having a high affinity for peptides that signal the transduction pathways for mitogenesis, cellular differentiation and embryogenesis. We now report an FGFR2 mutation in the conserved region of the immunoglobulin Illc domain in the Jackson-Weiss syndrome family in which the syndrome was originally described. In addition, in four of 12 Crouzon syndrome cases, we identified two new mutations and found two previously described mutations in the same region.

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. Individuals with SCS also have droopy eyelids (ptosis), widely spaced eyes (hypertelorism), and minor birth defects of the hands and feet (syndactyly). In addition, individuals with more severe cases of SCS may have mild to moderate mental retardation or learning disabilities. Depending on the level of severity, some individuals with SCS may require some form of medical or surgical intervention. Most individuals with SCS live fairly normal lives, regardless of whether medical treatment is needed or not. Individuals with SCS are all affected differently. Even within the same family, affected individuals have different features. The majority of individuals with SCS are ...
Pathophysiology: Crouzon syndrome is caused by mutations in the fibroblast growth factor receptor-2 (FGFR2) gene but exhibits locus heterogeneity with causal mutations in FGFR2 and FGFR3 in different affected individuals. Premature synostosis of the coronal, the sagittal, and, occasionally, the lambdoidal sutures begins in the first year of life and is completed by the second or third year. The order and rate of suture fusion determine the degree of deformity and disability. Once a suture becomes fused, growth perpendicular to that suture becomes restricted, and the fused bones act as a single bony structure. Compensatory growth occurs at the remaining open sutures to allow continued brain growth. However, multiple sutural synostoses frequently extend to premature fusion of the skull base sutures, causing midfacial hypoplasia, shallow orbits, a foreshortened nasal dorsum, maxillary hypoplasia, and occasional upper airway obstruction ...
Crouzon syndrome, also called craniofacial dysostosis, is an autosomal dominant disorder with complete penetrance and variable expressivity. Described by a French neurosurgeon in 1912, it is a rare genetic disorder characterized by premature closure of cranial sutures, midfacial hypoplasia, and orbital defects. Here, we report a case of this rare entity. The patient presented with brachycephaly, maxillary hypoplasia, exophthalmos, mandibular prognathism, along with dental and orbital abnormalities.
Gorlin-Chaudhry-Moss syndrome is a condition that affects many parts of the body. The signs and symptoms of this disorder are apparent from birth or infancy.. Gorlin-Chaudhry-Moss syndrome is characterized by the premature closure of certain bones of the skull (craniosynostosis) during development, which affects the shape of the head and face. Many people with this disorder have a premature fusion of skull bones along the coronal suture, the growth line that goes over the head from ear to ear. These changes can result in a head that is abnormally wide and pointed at the top (acrobrachycephaly). Affected individuals also have distinctive facial characteristics that can include a flat or sunken appearance of the middle of the face (midface hypoplasia), and small eyes (microphthalmia) with narrowed openings (narrowed palpebral fissures). Affected individuals may also have farsightedness (hyperopia) and dental problems such as small teeth (microdontia) or fewer teeth than normal (hypodontia).. Many ...
Pregnancies may be complicated by polyhydramnios. Infants are born with craniosynostosis with a cloverleaf pattern usually. The skull is often shortened in the anteroposterior axis with flattening of the occipital region. The skin is deeply furrowed with the cutis gyrata patterns most prominent in the posterior scalp but also present on the palms, soles, pinnae, and elsewhere. Acanthosis nigricans is often present.. There is midface hypoplasia and nearly all individuals have intellectual disability.. The external ear canals can be atretic, the nares are often anteverted, and the mouth may be small. An excess number of neonatal teeth and hypoplastic nails have been noted. Hydrocephalus is common. The umbilical stump is often unusually prominent. Anogenital anomalies such as an anteriorly placed anus, cryptorchidism, and bifid scrotum may be present. Pyloric stenosis is sometimes present.. Upper airway obstruction with respiratory distress may necessitate a tracheotomy. A cartilaginous tracheal ...
Infants with frontofacionasal dysplasia typically have distinctive malformations of certain bones forming the skull as well as additional facial, nasal, and eye (ocular) defects. For example, the disorder may be associated with premature closure of the fibrous joints (sutures) between particular bones of the skull (craniosynostosis), causing the head to appear unusually short and broad (brachycephaly). In addition, there may be early conversion of fibrous tissue into bone (early ossification) within the base of the skull (sphenoid bone), and some of the air-filled cavities (i.e., paranasal ethmoidal sinuses) within certain bones around the nose may be abnormally large. Underdevelopment of the middle portion of the face (midface hypoplasia) also occurs.. Affected infants may also have additional, associated skull defects, such as underdevelopment (hypoplasia) of part of the bone forming the front of the skull (frontal bone) and an abnormal opening (congenital cleft) within the frontal bone ...

Facial findings include midface hypoplasia (where the centre of the face develops more slowly than the eyes, forehead, and lower jaw). In Apert syndrome, the hypoplasia is generally moderate to severe with hypoplasia of the maxilla, shallow orbits, strabismus, hypertelorism, down-slanting palpebral fissures, proptosis, as well as depressed nasal bridge and deviated nasal septum.. Dental findings include delayed appearance of the teeth which may also be impacted and crowded in the mouth with thick, swollen gums. Unilateral and bilateral posterior crossbites are frequent. A posterior crossbite occurs when the top back teeth bite inside the bottom back teeth. Common associated complications include chronic otitis media (ear infections), hearing loss, and increased ocular (eye) pressure that can cause blindness.. Moderate to severe intellectual disability and variable developmental delay are also common in AS (more than 50% of cases). Some patients are also reported to have agenesis of the corpus ...
Apert syndrome is a rare genetic disorder that manifests as craniosynostosis, craniofacial and limb dysmorphic features. Mutations in fibroblast growth factor receptor 2 (FGFR2) gene account for almost all cases. Given the impact it can have throughout life, prenatal management becomes a challenge. A healthy 33-year-old woman, gravida 4, para 0, was referred to routine ultrasound at 22 weeks of gestation. Atypical cranial morphology with prominent forehead, ocular proptosis, hypertelorism and mitten hands were detected. Genetic investigation revealed an FGFR2 gene mutation (c.755C,G(p.Ser252Trp)), confirming the diagnosis. Magnetic resonance showed brachycephaly, turricephaly and cortical malformation. Following counselling, parents requested medical termination of pregnancy. Macroscopic features were consistent with ultrasound findings. This case emphasises the importance of early diagnosis to provide the best family counselling and prenatal management. A multidisciplinary team, consisting of ...

Of 316 screened records, 10 met the inclusion criteria, of which 3 were included in the meta-analysis. These studies reported on 303 patients treated endoscopically and 385 patients treated with open surgery. Endoscopic surgery was associated with lower estimated blood loss (p , 0.001), shorter length of stay (p , 0.001), and shorter operating time (p , 0.001). From the literature review of the 10 studies, transfusion rates for endoscopic procedures were consistently lower, with significant differences in 4 of 6 studies; the cost was lower, with differences ranging from $11,603 to $31,744 in 3 of 3 studies; and the cosmetic outcomes were equivocal (p , 0.05) in 3 of 3 studies. Finally, endoscopic techniques demonstrated complication rates similar to or lower than those of open surgery in 8 of 8 studies. ...
Worried for their sons health, the new parents took Gabriel to a pediatrician, who diagnosed the newborn with unilateral coronal synostosis - also known as anterior plagiocephaly.

Craniosynostosis (CS) identifies the band of craniofacial malformations seen as a the premature closure of 1 or even more cranial sutures. overexpression promote osteoblast calcification SCH 54292 cost and differentiation, phenotype of our individual may derive from misexpression from the genes. Predicated on our results, we hypothesize that both and could end up being implicated in the pathogenesis of CS in human beings. However, further research are had a need to establish the precise pathomechanism underlying advancement of the defect. genes (OMIM). Various other less regular disorders derive from different mutations in the genes (Jabs et al. 1993; Twigg et al. 2009, 2013; Hurst et al. 2011; Keupp et al. 2013; Sharma et al. 2013; Kutkowska-Kazmierczak et al. 2018). Conversely, small is well known about hereditary etiology of isolated CS and in nearly all cases the root molecular defect continues to be unidentified. Nonetheless, several studies have confirmed that complex types of the disease ...
This brachysphenocephalic type of acrocephaly is associated with syndactyly in the hands and feet. Pre- and postaxial polydactyly may be present. There is considerable variation in expression with some patients so mildly affected that they appear virtually normal, whereas others have extreme degrees of brachycephaly with high foreheads, midface hypoplasia, and proptosis secondary to shallow orbits. Imaging often reveals one or more CNS anomalies such as defects of the corpus callosum, partial absence of the septum pellucidum, ventriculomegaly, and sometimes hydrocephalus. A small but significant proportion of patients have some developmental delay and cognitive impairment. Over 39% of patients have a normal IQ.. ...

Raman spectral imaging provides the means to study spatially localized response to controlled external perturbations to tissue specimens with light microscopy resolution. We discuss use of heparin-acrylic microbeads soaked with the protein fibroblast growth factor-2 (FGF2). Microbeads containing FGF2 are placed in murine calvarial tissue and stimulate abnormally rapid mineralization. The tissue response simulated the effects of craniosynostosis, a birth defect occurring in 1 in 2400 live births. We describe Raman imaging measurements of the spatial distribution of apatitic mineral and matrix (predominantly type I collagen) from normal murine calvarial tissue and murine calvarial tissue modeling craniosynostosis. We also discuss spectroscopic evaluation of the state of the mineral induced by the FGF2 beads ...

Cranioectodermal dysplasia (CED) is an autosomal recessive ciliopathy characterized by sagittal craniosynostosis, skeletal, facial and ectodermal abnormalities. Findings typically include: dolichocephaly, hypertelorism, frontal and occipital bossing, telecanthus, epicanthal folds or narrow palpebral fissures, retinitis pigmentosa, low set ears, everted lower lip, fine sparse hair, dental abnormalities consisting of hypoplastic, widely spaced or fused teeth, short limbs, brachydactyly, narrow chest with short ribs, and skin laxity. Some patients have been reported with renal failure due to nephronophthisis or hepatic failure. CED is also known as Sensenbrenner syndrome. CED is known to be caused by mutations in at least four genes, IFT122, WDR35, IFT43 and WDR19. Mutations in IFT122 cause CED1 (MIM 218330), while mutations in WDR35, IFT43 and WDR19 cause CED2 (MIM 613610), CED3 (MIM 614099) and CED4 (MIM 614378), respectively. The products of these genes are components of cilia. Autosomal ...
Gain-of-function mutations in FGFR1, FGFR2 and FGFR3 are responsible for many forms of craniosynostosis and dwarfism syndromes. With significance to the mission of the Growing Stronger Organization, Dr. Mohammadis lab has elucidated the structural basis by which these pathogenic mutations lead to over-activation of FGFRs in these skeletal diseases. His structural and biochemical analysis of pathogenic gain-of-function mutations in the tyrosine kinase domain of FGFR have led to the discovery of a novel autoinhibitory "molecular brake" at the kinase hinge/interlobe region that is disengaged to different extent by different mutations, leading to a range of ligand-independent activation of FGFR. Likewise his structural and biochemical investigations of ligand-dependent FGFR2c p.S252W and FGFR2c p.P253R mutations, responsible for Apert syndrome (AS), have revealed that these mutations introduce additional contacts between the mutated FGFR and FGF to increase the affinity of the mutated FGFR for both ...
