Abstract
Serpentine fibula-polycystic kidney syndrome (SFPKS) is a rare disorder characterized by the association of craniofacial anomalies, radiological findings (wormian bones, elongated and bowed fibulae), polycystic kidneys, and normal intelligence. SFPKS shares many similarities with Hajdu-Cheney syndrome (HCS). We and others recently showed that truncating mutations in the last exon of NOTCH2 cause HCS. Here, we identify by Sanger sequencing two different heterozygous truncating mutations in the last exon of NOTCH2 in two unrelated patients with SFPKS. In one family, we show that the mutation occurred de novo. These findings demonstrate that SFPKS and HCS are both conditions caused by NOTCH2 mutations.

Abstract
Serpentine fibula polycystic kidney syndrome (SFPKS; MIM600330) is a rare skeletal dysplasia that has polycystic kidneys and dysmorphic facies as additional defining phenotypic components. The nosological classification of this disease has been debated as the condition shares features common to other skeletal dysplasias such as Melnick Needles syndrome (MNS; MIM309350) and Hajdu-Cheney Syndrome (HCS; MIM102500). Here, two previously reported cases of SFPKS are presented with emphasis on their phenotypic evolution. With the recent discovery that HCS is caused by mutations in NOTCH2, DNA from the both cases was examined and both were found to have truncating mutations in exon 34 of NOTCH2. The phenotypic evolution of SFPKS and this molecular analysis strongly suggest that SFPKS is part of the phenotypic spectrum of HCS and should no longer be classified as a distinct disease entity.

Abstract
Hajdu-Cheney syndrome is a rare, autosomal dominant skeletal dysplasia marked by acro-osteolysis of the distal phalanges and severe osteoporosis. Although there are more than 60 reports published to date, proper treatment and subsequent outcome have been scarce. Herein, we report a progress of anti-resorptive therapy with zoledronic acid, in a woman with Hajdu-Cheney syndrome. Results suggest that anti-resorptive therapy may be important in delaying the progress of osteoporosis and preventing fractures, but not necessarily acro-osteolysis itself.

Abstract
The genetic architecture of the craniofacial complex has been the subject of intense scrutiny because of the high frequency of congenital malformations. Numerous animal models have been used to document the early development of the craniofacial complex, but few studies have focused directly on the genetic underpinnings of normal variation in the human craniofacial complex. This study examines 80 quantitative traits derived from lateral cephalographs of 981 participants in the Fels Longitudinal Study, Wright State University, Dayton, Ohio. Quantitative genetic analyses were conducted using the Sequential Oligogenic Linkage Analysis Routines analytic platform, a maximum-likelihood variance components method that incorporates all familial information for parameter estimation. Heritability estimates were significant and of moderate to high magnitude for all craniofacial traits. Additionally, significant quantitative trait loci (QTL) were identified for 10 traits from the three developmental components (basicranium, splanchnocranium, and neurocranium) of the craniofacial complex. These QTL were found on chromosomes 3, 6, 11, 12, and 14. This study of the genetic architecture of the craniofacial complex elucidates fundamental information of the genetic architecture of the craniofacial complex in humans.

Abstract
We used an exome-sequencing strategy and identified an allelic series of NOTCH2 mutations in Hajdu-Cheney syndrome, an autosomal dominant multisystem disorder characterized by severe and progressive bone loss. The Hajdu-Cheney syndrome mutations are predicted to lead to the premature truncation of NOTCH2 with either disruption or loss of the C-terminal proline-glutamate-serine-threonine-rich proteolytic recognition sequence, the absence of which has previously been shown to increase Notch signaling.

Abstract
Hajdu-Cheney syndrome is a rare autosomal dominant skeletal disorder with facial anomalies, osteoporosis and acro-osteolysis. We sequenced the exomes of six unrelated individuals with this syndrome and identified heterozygous nonsense and frameshift mutations in NOTCH2 in five of them. All mutations cluster to the last coding exon of the gene, suggesting that the mutant mRNA products escape nonsense-mediated decay and that the resulting truncated NOTCH2 proteins act in a gain-of-function manner.

Abstract
Hajdu-Cheney syndrome is a rare, probably autosomal dominant connective tissue disorder with a variable expressivity. It is characterized by an osteoporotic skeleton, acro-osteolysis, a proportionate short stature, and distinctive orofacial anomalies. The aim of this article is to focus on the orofacial manifestations in two sporadic cases and one familial case with Hajdu-Cheney syndrome. Several common dental and craniofacial features are described. In contrast to earlier proposed diagnostic features, these patients show persisting deciduous teeth, problematic tooth eruption, and tendency toward a Class III malocclusion.

Six patients who presented with craniofacial anomalies, musculoskeletal anomalies including elongated and bowed (serpentine) fibulae, and polycystic kidneys are reported. This association of anomalies is referred to as serpentine fibula polycystic kidney syndrome (SFPKS) and is currently interpreted as a manifestation of Hajdu-Cheney syndrome (HCS). We report a new instance of this association of anomalies and review the clinical and radiographic features of HCS and of the reported cases of SFPKS.

Abstract
INTRODUCTION Osteogenesis imperfecta (OI) is an inheritable disorder of bone development caused by defective collagen synthesis. The attendant basilar impression or secondary basilar invagination is uncommon but can be devastating. CLINICAL MATERIALS AND METHODS Fifty-two patients with osteochondrodysplasia (28 with OI, six with Hajdu-Cheney syndrome, six with Paget's disease, and 12 with spondyloepiphyseal dysplasia) with basilar impression were evaluated between 1985 and 2005. The male/female ratio in this cohort was 1:1. The mean age at presentation was 12.2 years. SYMPTOMS Symptoms and signs included headache, lower cranial nerve dysfunction, dysphagia, respiratory embarrassment, weakness, and ataxia. TREATMENT In the earlier part of the series (1985-1995), all patients with hydrocephalus were shunted and a ventral transoral decompression made for ventral compression of the pontomedullary junction followed by a dorsal occipitocervical fusion. As a result of this evaluation, it was felt that most patients would benefit by early bracing after the hydrocephalus was shunted if it existed. However, 20% of patients still required an anterior ventral decompression and the occipitocervical fusion. RESULTS The results showed that the fusions were stable but over a period of time, there was progressive forward bending with osteogenesis imperfecta as well as with the Hajdu-Cheney syndrome. All patients with spondyloepiphyseal dysplasia had a good strong stable fusion which stood the test of time. CONCLUSION In conclusion, we feel that early intervention with occipitocervical bracing can prevent the progressive march of significant basilar impression which leads to mortality.

Abstract
Hajdu-Cheney syndrome (MIM 102500) is a rare skeletal dysplasia marked by severe generalized osteoporosis and focal bone loss (acro-osteolysis). Osteoporosis treatment outcome has been reported only once previously. Reported herein is the biochemical and densitometric response to integrated anti-remodeling and anabolic therapy in a woman with Hajdu-Cheney syndrome. Results suggest dissociation of bone formation from bone resorption resulting in dramatic increases in bone mineral density without clinical evidence of activated osteoporosis.

Abstract
Several disorders characterized primarily by anomalies of the skeleton have recently been shown to be caused by mutations in the X-linked gene, FLNA. One of these conditions, the Melnick-Needles syndrome exhibits a phenotype that shares overlap with that of serpentine fibula-polycystic kidney syndrome and the autosomal dominant condition, Hajdu-Cheney syndrome. Here, we describe three individuals with these diagnoses. The individual with serpentine fibula-polycystic kidney syndrome, the fifth case reported in the literature, exhibited wormian bones which further expands the phenotypic spectrum for this condition and extends the overlap with Hajdu-Cheney syndrome. All three members of the filamin gene family, FLNA, and its functionally related paralogues, FLNB and FLNC, were screened for pathogenic mutations in all three individuals. We found a mutation in FLNA in the individual with Melnick-Needles syndrome, but no pathogenic variants in any filamin gene in the two individuals with Hajdu-Cheney syndrome and serpentine fibula-polycystic kidney syndrome. Clinical and molecular evidence indicates that Melnick-Needles syndrome is aetiologically distinct from Hajdu-Cheney syndrome and serpentine fibula-polycystic kidney syndrome, but these two latter conditions share many clinical similarities and may prove to be allelic to one another.

We report on a patient with blepharophimosis who after unsuccessful surgery developed progressive corneal vascularization. The patient had conductive hearing loss, acroosteolysis of the phalanges, arthropathy, loss of subcutaneous fat of the hands, feet and face, and oligospermia. He had had spontaneous pneumothorax four times. We have found no similar case reports in the literature and suggest that this is a new syndrome, which must be differentiated from hereditary mucoepithelial dysplasia, mandibuloacral dysplasia, keratitis-ichthyosis-deafness syndrome, Hajdu-Cheney syndrome, Penttinen syndrome, and mucopolysaccharidoses.

Abstract
We report three members of an Armenian family with Hajdu-Cheney syndrome. The history suggested that five other members of the family were also probably affected. This disorder is important for the radiologist because distinctive radiographic findings make the diagnosis possible before clinical signs and symptoms are fully developed. Additionally, radiographic examination is essential in all patients suspected of Hajdu-Cheney syndrome for confirmation of the clinical diagnosis. Radiographic examination also detects complications of the syndrome not evident on clinical examination.

Abstract
It is well recognized that many if not most children and adolescents attending paediatric rheumatology clinics will have a non-inflammatory origin for their complaints or disorder. Mechanical causes are frequently identified, and hypermobility or ligamentous laxity of joints is increasingly recognized as an aetiological factor in the presentation. Such conditions include 'growing pains', recurrent lower-limb arthralgia, anterior knee pain syndromes, and back pain. Studies of significant cohorts of such patients have now been published supporting the link of ligamentous laxity to particular symptom complexes. However, much disagreement remains as to the validity of hypermobility as an aetiogical factor. What seems clear is that not all hypermobile individuals will be symptomatic or indeed possibly have any risk for specific musculoskeletal disorders in later life. Screening tools such as the Beighton score are likely to be inadequate in many paediatric populations. Along with increasing recognition of these disorders in childhood and adolescence has been the development of a multidisciplinary management approach, which usually involves predominantly allied health professionals such as podiatrists, physiotherapists and occupational therapists. The challenge remains to interpret symptoms correctly as being related to the hypermobility and to predict why such children become symptomatic. The answer is likely to involve physiological and psychosocial factors. In addition, early identification and modification of risk factors may have major implications for subsequent prevalence of many adult medical disorders such as low back pain, chronic pain syndromes and degenerative osteoarthritis.

Abstract
The Museum Vrolik collection of anatomical specimens in Amsterdam, The Netherlands, comprises over 5,000 specimens of human and animal anatomy, embryology, pathology, and congenital anomalies. Recently, we rediagnosed a subset of the collection comprising dried infantile, juvenile, and adult human skulls with congenital and acquired conditions. On external examination and additional radiography, we found 58 skulls with craniosynostosis (CS) involving one or more sutures and 40 skulls with a presumed suture related condition. Most of these were part of the material collected and described by Louis Bolk (1866-1930). Analysis of his observations suggests that skull deformation because of premature suture closure depends not only on the identity of the sutures involved but also on the timing and progression of their closure and the extent of their involvement. Moreover, premature closure of the sagittal suture after 3-6 years of age appeared to be much more common than expected because it is not accompanied by skull deformation. Many of the skulls with single-suture CS were microcephalic, which may be the cause of the premature synostosis. By contrast, microcephaly may be a resulting phenomenon in multi-suture CS. We noticed that the quotient between height of the cranial vault (vertex-porion distance) and head circumference, multiplied by 100, was 26 or higher only in those CS cases with multi-suture involvement. We therefore consider this parameter, which we named "acrocephalic index", to be an indicator of multi-suture involvement in individual CS cases. In two adult skulls, the skull had a quadrangular shape, which we assumed to be correlated to the presence of an unusually interdigitated open metopic suture. We propose to name this anomaly: tetragonocephaly. Another presumed suture-related condition, bathrocephaly, was found concomitantly with basilar invagination in several cases. We hypothesize that the chronically raised intracranial pressure in these cases caused the still open lambdoidal sutures to distend and the occipital bone to protrude.

Abstract
This 7-year-old boy with Hajdu-Cheney syndrome presented with cervical syringomyelia related to rapidly progressing platybasia. Decompressive craniectomy provided temporary improvement, and his clinical status was eventually stabilized after external immobilization, according to findings at 2.5 years of follow up. In a review of the literature the authors found 57 cases of the syndrome, only three of which were associated with syringomyelia. The youth of the patient, the severe form and rapid course of the disease, and the very specific anatomical conditions related to cranial and facial deformities raised various therapeutic problems.
