Abstract
BACKGROUND 22q11.2 deletion syndrome (22q11.2DS) is a very broad phenotypic spectrum disorder. It can affect many organs or systems. 22q11.2DS is the most common microdeletion syndrome in humans, with a prevalence ranging from one in every 2000 to one in 4000 newborns. It seems to be more prevalent than reported and under-recognized or undiagnosed because of its inherent clinical variability and heterogeneity. In France, 15,000 patients may be affected by this disease, more than half without knowing it. The aim of this study was to analyze the care pathway before the genetic diagnosis of 22q11.2DS. METHODS We conducted a single-center, retrospective analysis of postnatally diagnosed patients recruited by the cytogenetic laboratory of Nancy (France) from January 2000 to December 2015. Clinical data were first collected by consulting the medical files of patients and then by calling them directly. Written informed consent was obtained and the study was approved by local research ethics boards. Data concerned only clinical features before the diagnosis. RESULTS The cohort consisted of 32 individuals with 22q11.2DS. The average age at diagnosis was 9 years and 2 months and the median age was 2 years and 11 months. Fetal echography was abnormal in 15 pregnancies. During the neonatal period, the most important features were eating difficulties and congenital malformations (n=20), with a majority of complex heart diseases (n=16), dominated by conotruncal malformations (n=6). In case of malformation, the average age at diagnosis decreased to 2 years and 6 months. A congenital heart disease brought the average age of diagnosis down to 2 years and 6 months. Hypocalcemia and dysmorphism were also classical features (n=14). Before the age of 3 years, speech delay occurred in nine patients. After 3 years of age, rhinolalia was predominant (n=11). Academic disabilities were present in all subjects. At least 14 patients had a de novo deletion. Five patients were diagnosed within genetic counseling, with the deletion was inherited from the mother in three out of four cases. One was the monozygotic twin of a patient. Seven patients were diagnosed as adults. Four of them were diagnosed only because of the clinical presentation of their children or fetuses. Retrospectively, all adult patients had clinical signs suggesting the 22q11.2DS diagnosis. Relational disorders affected eight patients. None of them had been referred to the geneticist for this reason. In most cases, the pediatric cardiologist referred patients to the geneticist (n=9). Physiotherapists (n=15) and speech-language pathologists (n=12) were frequently requested but did not participate in the diagnosis. CONCLUSION The present study highlights the difficulty of establishing the diagnosis when the major features of the 22q11.2DS are absent during the 1st months of life. This is particularly true when there is no congenital defect. Special attention must be given to speech disorders in childhood and neuropsychological disorders later in life. The association between 22q11.2DS and early-onset parkinson disease implies that adult neurologists should be aware of this diagnosis. For adult patients, familial occurrence is the most frequent cause of diagnosis in spite of clinical signs suggestive of 22q11.2DS. The management of these patients involves better information of medical and paramedical staff in order to refer them to the geneticist earlier in life.

Abstract
Patients under 5 years were not evaluated in the phase-3 study for enzyme replacement therapy (ERT) in MPS IV A. Here we describe the evolution of a severe Morquio A pediatric patient who was diagnosed at 19 months old and treated by ERT at 21 months old for the next 30 months. Applying the standard ERT protocol on this very young patient appeared to reduce his urinary excretion of glycosaminoglycans (GAGs); the improvements in both the 6 minute-walk test (6MWT) and the stair climb test, however, were no different than those reported in the nature history study. Additionally, this young patient experienced many ERT-associated side effects, and as a result a specific corticosteroid protocol (1 mg/kg of betamethasone the day before and 1 h before the ERT infusion) was given to avoid adverse events. Under these treatments, the height of this patient increased during the first year of the ERT although no more height gain was observed thereafter for 18 months. However, despite of ERT, his bone deformities (including severe pectus carinatum) actually worsened and his medullar cervical spine compression showed no improvement (thus needed decompression surgery). CONCLUSION early ERT treatment did not improve the bone outcome in this severe MPS IV A patient after the 30 months-long treatment. A longer term follow up is required to further assess the efficacy of ERT on both the motor and the respiratory function of the patient.

Abstract
Microarray-based comparative genomic hybridization (aCGH) is commonly used in diagnosing patients with intellectual disability (ID) with or without congenital malformation. Because aCGH interrogates with the whole genome, there is a risk of being confronted with incidental findings (IF). In order to anticipate the ethical issues of IF with the generalization of new genome-wide analysis technologies, we questioned French clinicians and cytogeneticists about the situations they have faced regarding IF from aCGH. Sixty-five IF were reported. Forty corresponded to autosomal dominant diseases with incomplete penetrance, 7 to autosomal dominant diseases with complete penetrance, 14 to X-linked diseases, and 4 were heterozygotes for autosomal recessive diseases with a high prevalence of heterozygotes in the population. Therapeutic/preventive measures or genetic counselling could be argued for all cases except four. These four IF were intentionally not returned to the patients. Clinicians reported difficulties in returning the results in 29% of the cases, mainly when the question of IF had not been anticipated. Indeed, at the time of the investigation, only 48% of the clinicians used consents mentioning the risk of IF. With the emergence of new technologies, there is a need to report such national experiences; they show the importance of pre-test information on IF.

Abstract
Sandifer's syndrome is a dystonic movement disorder in infants with gastroesophageal reflux (GER). It is probably misdiagnosed as epileptic seizures. We report the case of a 5-month-old infant with no past medical history admitted to a pediatric unit for suspicion of infantile spasms. She presented with dystonic movements of the upper left limb with left blepharospasm and an occasional dystonic head posture. Physical examination, EEG, brain MRI, and blood analysis were normal. Since the baby experienced regurgitations, Sandifer's syndrome was suspected and confirmed by 24-h esophageal pH monitoring that documented pathological GER. The dystonic symptoms quickly disappeared under treatment with thickened infant formula and sodium alginate. Infantile spasms remain the first diagnosis to explore with axial or para-axial dystonic postural events. Sandifer's syndrome should be retained when neurological investigations are normal and abnormal movements disappear under treatment of proven GER. Prognosis is excellent.

Abstract
Cutaneous lesions described as chilblain lupus occur in the context of familial chilblain lupus or Aicardi-Goutières syndrome. To date, seven genes related to Aicardi-Goutières syndrome have been described. The most recently described encodes the cytosolic double-stranded RNA receptor IFIH1 (also known as MDA5), a key component of the antiviral type I interferon-mediated innate immune response. Enhanced type I interferon signalling secondary to gain-of-function mutations in IFIH1 can result in a range of neuroinflammatory phenotypes including classical Aicardi-Goutières syndrome. It is of note that none of the patients with a neurological phenotype so far described with mutations in this gene was reported to demonstrate cutaneous involvement. We present a family segregating a heterozygous pathogenic mutation in IFIH1 showing dermatological involvement as a prominent feature, variably associated with neurological disturbance and premature tooth loss. All three affected individuals exhibited increased expression of interferon-stimulated genes in whole blood, and the mutant protein resulted in enhanced interferon signalling in vitro, both in the basal state and following ligand stimulation. Our results further extend the phenotypic spectrum associated with mutations in IFIH1, indicating that the disease can be confined predominantly to the skin, while also highlighting phenotypic overlap with both Aicardi-Goutières syndrome and Singleton-Merten syndrome.

Abstract
INTRODUCTION Madelung's deformity is a bone dysplasia that occurs predominantly in adolescent females, characterized by early epiphyseal growth arrest in the medial part of the distal radius. This leads to an upward and medial displacement of the radial joint surface, restricting range of motion. OBJECTIVES The objective of this study was to determine whether there was a link between clinical and radiological data in children with Madelung's deformity and to test the hypothesis of a relation between the deformity and a genetic mutation. METHODS A retrospective study recruited 13 patients with Madelung's deformity, with a mean age of 13.2 years (range, 8-18 years). Assessment comprised level of pain, range of motion and grip force, with standard AP and lateral wrist X-rays. Every patient except one underwent molecular genetic screening, adhering to current recommendations. RESULTS Pronation-supination, radial inclination and grip force were significantly impaired compared to normal results. All X-ray measurements were significantly abnormal, except for the lunate-covering ratio. Genetic mutation (SHOX) was systematic in the 12 patients screened. DISCUSSION Radiological deformity did not correlate with functional disturbance or pain. Non-acquired Madelung's deformity requires molecular screening for SHOX or XO mutation, which definitively diagnoses Léri-Weill dyschondrosteosis or Turner syndrome. CONCLUSION A larger series is necessary to confirm these preliminary results, which nevertheless suggest that non-acquired Madelung's deformity is not isolated but syndromic. Early detection of Léri-Weill or Turner syndrome is essential, due to their therapeutic specificities. LEVEL: IV.

Abstract
First described in 1983, Woodhouse-Sakati syndrome (WSS) is a rare autosomal recessive genetic disorder that leads to a spectrum of hypogonadal symptoms in adolescence. The responsible gene, DCAF17 located on chromosome 2q31.1, was discovered in 2008 and to date nine mutations have been reported in the literature. The aim of the study was to review WSS descriptively in the light of new case reports with focus on endocrine features. Phenotypic description of three patients (two females, one male) with WSS followed in the Endocrinology Department of the University Hospital of Nancy, France, and exhaustive review of the literature using the PUBMED database were performed. Of 72 patients from 29 families with documented WSS who were identified, 39 had undergone genetic testing. WSS was invariably associated with hypogonadism, decreased IGF1 and frontotemporal alopecia starting in childhood. In addition to this triad, some patients exhibited intellectual disabilities of varying severity (87 %), bilateral deafness (76 %), cervicofacial dystonia and limb pain (42 % of cases, rising to 89 % after 25 years) and diabetes (66 %, rising to 96 % after 25 years). The pathophysiology of WSS remains unclear.

Abstract
Rhombencephalosynapsis is an uncommon, but increasingly recognized, cerebellar malformation defined as vermian agenesis with fusion of the hemispheres. The embryologic and genetic mechanisms involved are still unknown, and to date, no animal models are available. In the present study, we used Agilent oligonucleotide arrays in a large series of 57 affected patients to detect candidate genes. Four different unbalanced rearrangements were detected: a 16p11.2 deletion, a 14q12q21.2 deletion, an unbalanced translocation t(2p;10q), and a 16p13.11 microdeletion containing 2 candidate genes. These genes were further investigated by sequencing and in situ hybridization. This first microarray screening of a rhombencephalosynapsis series suggests that there may be heterogeneous genetic causes.

Abstract
Chromosomal abnormalities are common in patients with oligozoospermia or azoospermia. We report the case of a 32-year patient, with male phenotype, and without hormonal or morphological abnormalities, with a severely reduced spermatogenesis. It was revealed a 45,X/46,XY gonadal dysgenesis. We have reviewed the various problems inherent in the discovery of this rare gonadal dysgenesis, including genetic, cancer and fertility risks.

Abstract
The association of marfanoid habitus (MH) and intellectual disability (ID) has been reported in the literature, with overlapping presentations and genetic heterogeneity. A hundred patients (71 males and 29 females) with a MH and ID were recruited. Custom-designed 244K array-CGH (Agilent®; Agilent Technologies Inc., Santa Clara, CA) and MED12, ZDHHC9, UPF3B, FBN1, TGFBR1 and TGFBR2 sequencing analyses were performed. Eighty patients could be classified as isolated MH and ID: 12 chromosomal imbalances, 1 FBN1 mutation and 1 possibly pathogenic MED12 mutation were found (17%). Twenty patients could be classified as ID with other extra-skeletal features of the Marfan syndrome (MFS) spectrum: 4 pathogenic FBN1 mutations and 4 chromosomal imbalances were found (2 patients with both FBN1 mutation and chromosomal rearrangement) (29%). These results suggest either that there are more loci with genes yet to be discovered or that MH can also be a relatively non-specific feature of patients with ID. The search for aortic complications is mandatory even if MH is associated with ID since FBN1 mutations or rearrangements were found in some patients. The excess of males is in favour of the involvement of other X-linked genes. Although it was impossible to make a diagnosis in 80% of patients, these results will improve genetic counselling in families.

Abstract
In our phenylketonuria (PKU) cohort of 120 patients, we uncovered a couple of cases of undiagnosed mild phenylketonuria (mPKU)/hyperphenylalaninemia (mHPA) in maternal parents of the PKU cohort. This finding prompted us to evaluate the risk of either mild phenylketonuria or mild hyperphenylalaninemia in the parent population whose children were diagnosed with hyperphenylalaninemia (HPA). Taking into account the phenylalanine hydroxylase (PAH) mutation carrier frequency and the PAH mild mutation rate, we estimated that the prevalence of the parental mPKU/mHPA varied widely, from 1/74 in Turkey to 1/708 in Lithuania. The benefits of the parental detection procedure described here are the prevention of further maternal PKU syndrome, the follow-up of the newly detected patients and the accuracy of the genetic counseling provided to these families. This very simple procedure should be incorporated into neonatal PKU management of the hospitals in countries where a routine systematic neonatal screening is operational.

Abstract
The striking excess of affected males in autism spectrum disorders (ASD) suggests that genes located on chromosome X contribute to the etiology of these disorders. To identify new X-linked genes associated with ASD, we analyzed the entire chromosome X exome by next-generation sequencing in 12 unrelated families with two affected males. Thirty-six possibly deleterious variants in 33 candidate genes were found, including PHF8 and HUWE1, previously implicated in intellectual disability (ID). A nonsense mutation in TMLHE, which encodes the ɛ-N-trimethyllysine hydroxylase catalyzing the first step of carnitine biosynthesis, was identified in two brothers with autism and ID. By screening the TMLHE coding sequence in 501 male patients with ASD, we identified two additional missense substitutions not found in controls and not reported in databases. Functional analyses confirmed that the mutations were associated with a loss-of-function and led to an increase in trimethyllysine, the precursor of carnitine biosynthesis, in the plasma of patients. This study supports the hypothesis that rare variants on the X chromosome are involved in the etiology of ASD and contribute to the sex-ratio disequilibrium.

Abstract
Microcephalic osteodysplastic primordial dwarfism type II (MOPD II, MIM 210720) and Seckel syndrome (SCKL, MIM 210600) belong to the primordial dwarfism group characterised by intrauterine growth retardation, severe proportionate short stature, and pronounced microcephaly. MOPD II is distinct from SCKL by more severe growth retardation, radiological abnormalities, and absent or mild mental retardation. Seckel syndrome is associated with defective ATR dependent DNA damage signalling. In 2008, loss-of-function mutations in the pericentrin gene (PCNT) have been identified in 28 patients, including 3 SCKL and 25 MOPDII cases. This gene encodes a centrosomal protein which plays a key role in the organisation of mitotic spindles. The aim of this study was to analyse PCNT in a large series of SCKL-MOPD II cases to further define the clinical spectrum associated with PCNT mutations. Among 18 consanguineous families (13 SCKL and 5 MOPDII) and 6 isolated cases (3 SCKL and 3 MOPD II), 13 distinct mutations were identified in 5/16 SCKL and 8/8 MOPDII including five stop mutations, five frameshift mutations, two splice site mutations, and one apparent missense mutation affecting the last base of exon 19. Moreover, we demonstrated that this latter mutation leads to an abnormal splicing with a predicted premature termination of translation. The clinical analysis of the 5 SCKL cases with PCNT mutations showed that they all presented minor skeletal changes and clinical features compatible with MOPDII diagnosis. It is therefore concluded that, despite variable severity, MOPDII is a genetically homogeneous condition due to loss-of-function of pericentrin.

Abstract
Constitutional interstitial deletions of 5q are relatively rare and most are poorly characterized cytogenetically. Consequently a definite karyotype-phenotype correlation is difficult to establish. We report on a new case of a girl presenting with an abnormal cry, upslanting palpebral fissures, hypertelorism, anteverted nostrils, microretrognathia, growth retardation, and an adenoid cyst at the base of the tongue. The first suspected diagnosis was cri-du-chat syndrome because of the mewing cry. Standard cytogenetic analyses were interpreted as normal, but FISH studies using the probe of cri-du-chat syndrome with the control probe EGR1 (5q31.2)/D5S23 (Abbott) revealed a 5q31.2 microdeletion which was then confirmed by CGH-array (Abbott). FISH studies using PACs and BACs clones (Rocchi, Italia) enabled us to characterize the breakpoints of the deleted region. Cytogenetic analysis with FISH studies revealed a normal karyotype with normal 5q31 region in both parents. This case is compared with the other cases reported in the literature.

Abstract
Males with duplications within the short arm of the X chromosome are rare and most cases are inherited from a maternal heterozygote. Here we describe the first detailed characterization of a de-novo Xp duplication delineated to Xp11.22-->Xp11.23 in a 15-year-old male with moderate mental impairment, autistic-like behaviour, short stature, and mild dysmorphic features. Chromosome analysis (550 band resolution) was normal and comparative genomic hybridization (CGH) analysis on metaphase spreads detected duplication on Xp11. Further characterization of the duplication by array CGH, FISH experiments with specific BAC probes, and genotyping with microsatellite markers helped to determine proximal and distal breakpoints giving a size of the duplication of approximately 5 Mb. As far as we are aware this is the first described male with isolated microduplication on Xp11.22-Xp11.23. Among the genes included within the duplicated region, and particularly those which are outside copy number polymorphisms, we discuss the relationship of FTSJ1, PQBP1 and HDAC6 with the clinical symptoms of our patient.

Abstract
The influence of physical and sporting activities (PSA) on idiopathic scoliosis (IS) is still obscure. The aim of this study was to investigate whether such an influence exists and if so, to determine its characteristics. Two hundred and one teenagers with IS and a control group of 192 adolescents completed an epidemiological questionnaire. Those practising gymnastics were more numerous in the IS group than in the control group. Moreover, the practice of gymnastics was chosen before IS was diagnosed. As gymnastic activities are considered neither as a therapy nor as a precursor of IS, the distribution observed could be linked to a common factor that both increases the likelihood of IS and favors the practice of gymnastics. Joint laxity (JL) may be such a common factor, and was therefore tested (wrist and middle finger) on 42 girls with IS and 21 girls of a control group. IS patients, practising gymnastics or not, showed a higher JL than the control group practising gymnastics or not. Furthermore, the groups practising gymnastic activities did not show higher JL levels than the other groups. Children with a high JL could be drawn toward gymnastics because of their ability to adapt to the constraints of this sport. Girls with a high JL may therefore be prone to developing IS. The fact that most teenagers with IS practise gymnastics could be related to a higher JL.

Abstract
Cohen syndrome (CS) is an autosomal recessive disorder with variability in the clinical manifestations, characterised by mental retardation, postnatal microcephaly, facial dysmorphism, pigmentary retinopathy, myopia, and intermittent neutropenia. Mutations in the gene COH1 have been found in an ethnically diverse series of patients. Brief clinical descriptions of 24 patients with CS are provided. The patients were from 16 families of different ethnic backgrounds and between 2.5 and 60 years of age at assessment. DNA samples from all patients were analysed for mutations in COH1 by direct sequencing. Splice site mutations were characterised using reverse transcriptase PCR analysis from total RNA samples. In this series, we detected 25 different COH1 mutations; 19 of these were novel, including 9 nonsense mutations, 8 frameshift mutations, 4 verified splice site mutations, 3 larger in frame deletions, and 1 missense mutation. We observed marked variability of developmental and growth parameters. The typical facial gestalt was seen in 23/24 patients. Early onset progressive myopia was present in all the patients older than 5 years. Widespread pigmentary retinopathy was found in 12/14 patients assessed over 5 years of age. We present evidence for extended allelic heterogeneity of CS, with the vast majority of mutations leading to premature termination codons in COH1. Our data confirm the broad clinical spectrum of CS with some patients lacking even the characteristic facial gestalt and pigmentary retinopathy at school age.

Abstract
Classical galactosaemia is an inherited inborn error of the major galactose assimilation pathway, caused by galactose-1-phosphate uridyltransferase (GALT) deficiency. Many GALT mutations have been described, with different clinical consequences. In severe forms, newborns present with a life-threatening, acute toxic syndrome that rapidly regresses under a galactose-restricted diet. However, long-term complications, particularly cognitive and motor abnormalities, as well as hypergonadotrophic hypogonadism in female patients are still unavoidable. The pathogenesis of galactose-induced ovarian toxicity remains unclear but probably involves galactose itself and its metabolites such as galactitol and UDP-galactose. Possible mechanisms of ovarian damage include direct toxicity of galactose and metabolites, deficient galactosylation of glycoproteins and glycolipids, oxidative stress and activation of apoptosis. As there is no aetiological treatment, clinical management of ovarian failure in galactosaemic patients principally relies on hormonal replacement therapy to induce pubertal development and to prevent bone loss and other consequences of estrogen deprivation. Further investigations will be necessary to better understand the metabolic flux of galactose through its biochemical pathways and the mechanisms of these secondary complications. The aim of this article is to present an extensive review on the pathogenesis and clinical management of galactose-induced premature ovarian failure.

Abstract
Mutations in ATRX are associated with a wide and clinically heterogeneous spectrum of X-linked mental retardation syndromes. The ATRX protein, involved in chromatin remodelling, belongs to the family of SWI/SNF DNA helicases and contains a plant homeodomain (PHD)-like domain. To date, more than 60 different mutations have been reported in ATRX. One of them is recurrent and accounts for 20% of all the reported mutations, whereas all others are private. Most mutations are clustered in the two major functional domains, the helicase and the PHD-like domain. So far, no clear genotype-phenotype correlation has been established, with exception to the rare truncating mutations located at the C-terminal part of the protein, which are consistently associated with severe urogenital defects. In this study, we report the molecular analysis performed in 16 families positive for ATRX. Our findings indicate that, in addition to the previously described mutation 'hotspot' in the PHD-like domain, two other protein sections emerge as minor 'hotspots' in the helicase region encoded by exons 18-20 and 26-29, respectively, gathering 33% of all described mutations. Additionally, based on the clinical data collected for 22 patients from the 16 families, we observe that mutations in the PHD-like domain produce severe and permanent psychomotor deficiency, usually preventing patients from walking, as well as constant urogenital abnormalities, while mutations in the helicase domain lead to delayed but correct psychomotor acquisitions together with mild or absent urogenital abnormalities. In summary, mutations in the helicase domain are associated with milder phenotypes than mutations in the PHD-like domain.

Abstract
Hypothyroidism is a well recognized complication of 22q11.2 deletion syndrome. Auto-immune hyperthyroidism is less common. We report three patients with a 22q11.2 deletion and Graves' disease diagnosed at age 17, 14 and 11 years, respectively. The clinical and biological presentation was typical for auto-immune hyperthyroidism. Graves' disease should be periodically sought during the follow-up program of patients with 22q11.2 deletion syndrome.

Abstract
Eight children developed osteochondroma (OS) at a mean of 88 months after hematopoietic stem cell transplantation (HSCT). The mean age at HSCT was 56 months (12-84). This represents a cumulative incidence of 20% among patients less than 18 years of age transplanted from 1981 to 1997. These eight patients underwent allogeneic (n = 2) or autologous (n = 6) transplantation for either acute leukemia (n = 6) or neuroblastoma (n = 2) after a conditioning regimen including TBI (n = 7) or a combination of Bu and CY. OS was multiple in seven patients and solitary in one. Eight lesions were resected and all were benign. Four children received growth hormone before diagnosis of OS, but there was no clinical, radiological or histological difference between those who did not. Univariate analysis showed an increased rate associated only with autologous HSCT, with a 31.7% probability of a new OS at 12 years after HSCT. Osteochondroma should be added to the other adverse effects of HSCT in children.

Abstract
The patient was the first child of first cousin parents. He was born at term after an uneventful pregnancy with normal height, weight and head circumference. Jaundice appeared at 15 days of age. Ventricular septal defects and valvular pulmonary stenosis were diagnosed. An hepatic workup revealed extrahepatic biliary atresia and abdominal situs inversus. Hepatic biopsy showed cirrhosis with intrahepatic cholestasis. Genetic factors are suggested in extrahepatic biliary atresia. Analysis of segregation patterns suggested the existence of two major groups, one with various combinations of anomalies within the laterality sequence and the other with one or two anomalies mostly involving the cardiac, gastrointestinal, and urinary systems. This patient belongs to the first group.

Abstract
The present study was conducted to further characterize the embryotoxic effects mono-n-butyl phthalate, a major metabolite of the plasticizer di-n-butyl phthalate, and evaluate its role in the developmental toxicity of di-n-butyl phthalate. The embryotoxic effects of mono-n-butyl phthalate were compared to those of the parent compound di-n-butyl phthalate after a single oral administration of 1.8, 3.6, 5.4, or 7.2 mmol/kg di-n-butyl phthalate or mono-n-butyl phthalate to Sprague-Dawley rats on gestational day 10 (Day 10). Embryos were evaluated for growth and development on Day 12. Both chemicals induced concentration-dependent developmental toxicity (i.e. decreased growth and malformations) which became apparent at 3.6 mmol/kg. Di-n-butyl phthalate and mono-n-butyl phthalate were approximately equally potent and produced qualitatively similar dysmorphogenic effects. Macroscopically, the most common malformations involved the prosencephalon, the optic system, and the mandibular and maxillary processes. In addition, the embryotoxic potential of mono-n-butyl phthalate was evaluated in vitro using the rat whole embryo culture system. Day 10 embryos were cultured for 48 hr in the presence of 0.5 to 5 mM mono-n-butyl phthalate and were then evaluated as the embryos grown in utero. Mono-n-butyl phthalate was a potent direct acting embryotoxicant, causing concentration-related growth retardation and dysmorphogenesis. The spectrum of morphological defects observed in mono-n-butyl phthalate-exposed embryos in vitro was comparable to those seen in vivo in the embryos at the same developmental stage after maternal administration of di-n-butyl phthalate or mono-n-butyl phthalate. These data provide additional evidence in support of the hypothesis that mono-n-butyl phthalate may be the active species for the developmental toxicity of ingested di-n-butyl phthalate in rats.

Abstract
The Li-Fraumeni syndrome (LFS) is an inherited form of cancer, affecting children and young adults, and characterized by a wide spectrum of tumors, including soft-tissue and bone sarcomas, brain tumours, adenocortical tumours and premenopausal breast cancers. In most of the families, LFS results from germline mutations of the tumor suppressor TP53 gene encoding a transcriptional factor able to regulate cell cycle and apoptosis when DNA damage occurs. Recently, germline mutations of hCHK2 encoding a kinase, regulating cell cycle via Cdc25C and TP53, were identified in affected families. The LFS working group recommendations are the following: (i) positive testing (screening for a germline TP53 mutation in a patient with a tumor) can be offered both to children and adults in the context of genetic counseling associated to psychological support, to confirm the diagnosis of LFS on a molecular basis. This will allow to offer to the patient a regular clinical review in order to avoid a delay to the diagnosis of another tumor; (ii) the 3 indications for positive testing are: a proband with a tumor belonging to the narrow LFS spectrum and developed before age 36 and, at least, first- or second-degree relative with a LFS spectrum tumor, before age 46, or a patient with multiple primary tumors, 2 of which belonging to the narrow LFS spectrum, the first being developed before 36 or a child with an adenocortical tumour; (iii) presymptomatic testing must be restricted to adults; (iv) the young age of onset of the LFS tumors the prognosis of some tumors, the impossibility to ensure an efficient early detection and the risk for mutation carriers to develop multiple primary tumors justify that prenatal diagnosis might be considered in affected families.

Abstract
UNLABELLED Schimke immuno-osseous dysplasia (SIOD) is a rare autosomal recessive spondylo-epiphyseal dysplasia. The characteristic features of SIOD include 1) short stature with hyperpigmented macules and an unusual facies, 2) proteinuria with progressive renal failure, 3) lymphopenia with recurrent infections, and 4) cerebral ischaemia. Although 25 patients have been reported with this disorder, the clinical course and phenotype of SIOD are not well characterized. This report summarizes the clinical findings, course and treatment of reported patients and includes 14 additional patients with SIOD. We emphasize the high incidence of cerebral ischaemia and ocular abnormalities, define the high incidence of thyroid dysfunction and blood cytopenia, and confirm the absence of effective and durable medical therapies. CONCLUSION Schimke immuno-osseous dysplasia is a multi-system autosomal recessive disorder with variable expression that affects the skeletal, renal, immune, vascular, and haematopoietic systems. Medical therapy is limited especially for more severely affected individuals.
