Abstract
Wiedemann-Steiner syndrome (WSS) is a rare syndromic condition in which intellectual disability (ID) is associated with hypertrichosis cubiti, short stature, and characteristic facies. Following the identification of the causative gene (KMT2A) in 2012, only 31 cases of WSS have been described precisely in the literature. We report on 33 French individuals with a KMT2A mutation confirmed by targeted gene sequencing, high-throughput sequencing or exome sequencing. Patients' molecular and clinical features were recorded and compared with the literature data. On the molecular level, we found 29 novel mutations. We observed autosomal dominant transmission of WSS in 3 families and mosaicism in one family. Clinically, we observed a broad phenotypic spectrum with regard to ID (mild to severe), the facies (typical or not of WSS) and associated malformations (bone, cerebral, renal, cardiac and ophthalmological anomalies). Hypertrichosis cubiti that was supposed to be pathognomonic in the literature was found only in 61% of our cases. This is the largest series of WSS cases yet described to date. A majority of patients exhibited suggestive features, but others were less characteristic, only identified by molecular diagnosis. The prevalence of WSS was higher than expected in patients with ID, suggesting than KMT2A is a major gene in ID.

Abstract
The group of chondrodysplasia with multiple dislocations includes several entities, characterized by short stature, dislocation of large joints, hand and/or vertebral anomalies. Other features, such as epiphyseal or metaphyseal changes, cleft palate, intellectual disability are also often part of the phenotype. In addition, several conditions with overlapping features are related to this group and broaden the spectrum. The majority of these disorders have been linked to pathogenic variants in genes encoding proteins implicated in the synthesis or sulfation of proteoglycans (PG). In a series of 30 patients with multiple dislocations, we have performed exome sequencing and subsequent targeted analysis of 15 genes, implicated in chondrodysplasia with multiple dislocations, and related conditions. We have identified causative pathogenic variants in 60% of patients (18/30); when a clinical diagnosis was suspected, this was molecularly confirmed in 53% of cases. Forty percent of patients remain without molecular etiology. Pathogenic variants in genes implicated in PG synthesis are of major importance in chondrodysplasia with multiple dislocations and related conditions. The combination of hand features, growth failure severity, radiological aspects of long bones and of vertebrae allowed discrimination among the different conditions. We propose key diagnostic clues to the clinician.

Abstract
Three overlapping conditions, namely Rothmund-Thomson (RTS), Baller-Gerold (BGS) and RAPADILINO syndromes, have been attributed to RECQL4 mutations. Differential diagnoses depend on the clinical presentation, but the numbers of known genes remain low, leading to the widespread prescription of RECQL4 sequencing. The aim of our study was therefore to determine the best clinical indicators for the presence of RECQL4 mutations in a series of 39 patients referred for RECQL4 molecular analysis and belonging to the RTS (27 cases) and BGS (12 cases) spectrum. One or two deleterious RECQL4 mutations were found in 10/27 patients referred for RTS diagnosis. Clinical and molecular reevaluation led to a different diagnosis in 7/17 negative cases, including Clericuzio-type poikiloderma with neutropenia, hereditary sclerosing poikiloderma, and craniosynostosis/anal anomalies/porokeratosis. No RECQL4 mutations were found in the BGS group without poikiloderma, confirming that RECQL4 sequencing was not indicated in this phenotype. One chromosomal abnormality and one TWIST mutation was found in this cohort. This study highlights the search for differential diagnoses before the prescription of RECQL4 sequencing in this clinically heterogeneous group. The combination of clinically defined subgroups and next-generation sequencing will hopefully bring to light new molecular bases of syndromes with poikiloderma, as well as BGS without poikiloderma.

Abstract
OBJECTIVE To assess the safety and efficacy of submucosal radiofrequency (RF) treatment for hereditary hemorrhagic telangiectasia (HHT) with mild or moderate epistaxis. METHODOLOGY We carried out a prospective pilot study of 16 consecutive patients with HHT-related epistaxis from June 2010 to April 2012. Under local anesthesia, RF was applied to one or both sides of the nose from the columella beneath the septal mucosal (50 joules per puncture). Patients were sent a questionnaire at least six months after the procedure. RESULTS RF under local anesthesia was well tolerated, according to visual analog scale scores. Neither crusting nor pain was reported one week after the intervention. The frequency of epistaxis per day and per month was significantly lower after RF. The duration of bleeding also decreased from more than 10 minutes to less than 5 minutes in two thirds of patients. Thirteen of the 16 patients were satisfied with the technique and would request it for subsequent procedures to treat repeated bleeding. CONCLUSION Submucosal RF treatment for HHT is a safe, well tolerated procedure with significant efficacy in the short term. It should be considered as an alternative technique for managing HHT-related epistaxis, although long-term results remain to be evaluated.

Abstract
Dystroglycanopathies are a heterogeneous group of muscular dystrophies with autosomal recessive inheritance characterized by abnormal glycosylation of alpha-dystroglycan. The most severe phenotypes are Walker-Warburg Syndrome (WWS) and muscle-eye-brain disease (MEB) presenting with lissencephaly type II (LIS II) and in which muscular dystrophy is associated with mental retardation and eye abnormalities. To date, six distinct genes, POMT1, POMT2, POMGNT1, FKTN, FKRP, LARGE and recently in one case DPM3, have been shown to be involved in dystroglycanopathies. Genomic sequencing alone is still frequently used for diagnosis purpose, not allowing detection of intragenic rearrangements at the heterozygous state contrarily to RNA analysis, quantitative PCR and CGH array analysis. These latter methods enabled us to identify four new intragenic rearrangements in the LARGE gene in three fetuses with WWS, born to two unrelated families: deletion of exons 9-10 and duplication of introns 1-4 for the first family and deletion of exons 4 and 7 for the second one; and a deletion of the last six exons of the POMGNT1 gene in two unrelated MEB patients. Genomic dosage studies using emerging tools such as CGH array should be included in routine molecular analysis of dystroglycanopathies, not only for the screening of the LARGE gene in which this kind of mutation seems to be more frequent than point mutations, but also for the other involved genes, especially in severe clinical cases.

Abstract
Van der Woude syndrome (VWS), caused by dominant IRF6 mutation, is the most common cleft syndrome. In 15% of the patients, lip pits are absent and the phenotype mimics isolated clefts. Therefore, we hypothesized that some of the families classified as having non-syndromic inherited cleft lip and palate could have an IRF6 mutation. We screened in total 170 patients with cleft lip with or without cleft palate (CL/P): 75 were syndromic and 95 were a priori part of multiplex non-syndromic families. A mutation was identified in 62.7 and 3.3% of the patients, respectively. In one of the 95 a priori non-syndromic families with an autosomal dominant inheritance (family B), new insights into the family history revealed the presence, at birth, of lower lip pits in two members and the diagnosis was revised as VWS. A novel lower lip sign was observed in one individual in this family. Interestingly, a similar lower lip sign was also observed in one individual from a 2nd family (family A). This consists of 2 nodules below the lower lip on the external side. In a 3rd multiplex family (family C), a de novo mutation was identified in an a priori non-syndromic CL/P patient. Re-examination after mutation screening revealed the presence of a tiny pit-looking lesion on the inner side of the lower lip leading to a revised diagnosis of VWS. On the basis of this data, we conclude that IRF6 should be screened when any doubt rises about the normality of the lower lip and also if a non-syndromic cleft lip patient (with or without cleft palate) has a family history suggestive of autosomal dominant inheritance.

Abstract
The increasing use of array-comparative genomic hybridization (array-CGH) to identify copy number variations (CNVs) in patients with developmental delay (DD), mental retardation and/or dysmorphic features has allowed the recent recognition of numerous genomic imbalances, including the 15q13.3 microdeletion. Patients with this microdeletion generally present with relatively consistent breakpoints at BP4 and BP5, which include the CHRNA7 gene. About 100 index cases have been reported since the first publication in 2008. This large number of patients ascertained through highly variable samples has been necessary to describe the full phenotypic spectrum of this microdeletion, ranging from mental retardation with dysmorphic features, epilepsy, neuropsychiatric disturbances with or without cognitive impairment to complete absence of anomalies. Here, we describe a collaborative study reporting a new cohort of 12 index patients and 13 relatives carrying a heterozygous BP4-BP5 microdeletion out of a series of 4625 patients screened by array-CGH for DD. We confirm the clinical expressivity of the disease as well as the incomplete penetrance in seven families. We showed through a review of the literature that males are more likely to be symptomatic. Sequence analysis of CHRNA7 yielded no data to support the unmasking of recessive variants as a cause of phenotypic variability. We also report the first patient carrying a 15q13.3 homozygous microdeletion inherited from both parents. He had severe epileptic encephalopathy with retinopathy, autistic features and choreoathetosis. Besides the classical approximately 1.5 Mb BP4-BP5 microdeletion, we also describe three index patients and two relatives with a smaller 500 kb microdeletion, including the CHRNA7 gene.

Abstract
Obesity has become a major worldwide challenge to public health, owing to an interaction between the Western 'obesogenic' environment and a strong genetic contribution. Recent extensive genome-wide association studies (GWASs) have identified numerous single nucleotide polymorphisms associated with obesity, but these loci together account for only a small fraction of the known heritable component. Thus, the 'common disease, common variant' hypothesis is increasingly coming under challenge. Here we report a highly penetrant form of obesity, initially observed in 31 subjects who were heterozygous for deletions of at least 593 kilobases at 16p11.2 and whose ascertainment included cognitive deficits. Nineteen similar deletions were identified from GWAS data in 16,053 individuals from eight European cohorts. These deletions were absent from healthy non-obese controls and accounted for 0.7% of our morbid obesity cases (body mass index (BMI) >or= 40 kg m(-2) or BMI standard deviation score >or= 4; P = 6.4 x 10(-8), odds ratio 43.0), demonstrating the potential importance in common disease of rare variants with strong effects. This highlights a promising strategy for identifying missing heritability in obesity and other complex traits: cohorts with extreme phenotypes are likely to be enriched for rare variants, thereby improving power for their discovery. Subsequent analysis of the loci so identified may well reveal additional rare variants that further contribute to the missing heritability, as recently reported for SIM1 (ref. 3). The most productive approach may therefore be to combine the 'power of the extreme' in small, well-phenotyped cohorts, with targeted follow-up in case-control and population cohorts.

Abstract
Bilateral periventricular nodular heterotopia (BPNH) is the most common form of periventricular heterotopia. Mutations in FLNA, encoding filamin A, are responsible for the X linked dominant form of BPNH (FLNA-BPNH). Recently, atypical phenotypes including BPNH with Ehlers-Danlos syndrome (BPNH-EDS) have been recognised. A total of 44 FLNA mutations have so far been reported in this phenotype. Most of these mutations lead to a truncated protein, but few missense mutations have also been described. Here, the results of a mutation screening conducted in a series of 32 BPNH patients with the identification of 12 novel point mutations in 15 patients are reported. Nine mutations were truncating, while three were missense. Three additional patients with BPNH-EDS and a mutation in FLNA are described. No phenotype-genotype correlations could be established, but these clinical data sustain the importance of cardiovascular monitoring in FLNA-BPNH patients.

Abstract
We present the first report of an association between hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS) and a specific form of congenital idiopathic intestinal pseudo-obstruction (CIIP) in an infant. Diagnosis of HSAS was suspected during the neonatal period because of a severely dilated ventricular system associated with bilateral adducted thumbs, and was confirmed by demonstration of a mutation in the gene encoding L1 cell adhesion molecule (L1CAM). L1CAM mutations cause a variable clinical spectrum. This gene is located at Xq28 and encodes a transmembrane glycoprotein involved in neurite outgrowth and neuronal migration. Hirschprung disease has been reported to involve an L1CAM mutation that manifests as a quantitative defect in the migration of neural crest cells in distal segments of the gut. We report an association that suggests that alterations of L1CAM may cause another type of intestinal pseudo-obstruction distension with a qualitative defect in differentiated Cajal's cells in the anterior part of the gut. This observation suggests that L1CAM has a role in the developmental regulation of multiple systems. Further clinical descriptions of gastroenterological and neuropathological data are required to extend our understanding of the mechanisms underlying L1CAM functions.

Abstract
Dyggve-Melchior-Clausen syndrome (DMC) is an autosomal recessive condition characterised by short trunk dwarfism, scoliosis, microcephaly, coarse facies, mental retardation, and characteristic radiological features. X rays show platyspondyly with double vertebral hump, epiphyseal dysplasia, irregular metaphyses, and a characteristic lacy appearance of the iliac crests. Electron microscopy of chondrocytes have shown widened cisternae of rough endoplasmic reticulum and biochemical analyses have shown accumulation of glucosaminoglycan in cartilage, but the pathogenesis of DMC remains unexplained. Here, we report on the homozygosity mapping of a DMC gene to chromosome 18q21.1 in seven inbred families (Zmax=9.65 at theta=0 at locus D18S1126) in the genetic interval (1.8 cM) defined by loci D18S455 and D18S363. Despite the various geographical origins of the families reported here (Morocco, Tunisia, Portugal, and Lebanon), this condition was genetically homogeneous in our series. Continuing studies will hopefully lead to the identification of the disease causing gene.

Abstract
Hirschsprung disease (HSCR) is a common malformation of neural-crest-derived enteric neurons that is frequently associated with other congenital abnormalities. The SMADIP1 gene recently has been recognized as disease causing in some patients with 2q22 chromosomal rearrangement, resulting in syndromic HSCR with mental retardation, with microcephaly, and with facial dysmorphism. We screened 19 patients with HSCR and mental retardation and eventually identified large-scale SMADIP1 deletions or truncating mutations in 8 of 19 patients. These results allow further delineation of the spectrum of malformations ascribed to SMADIP1 haploinsufficiency, which includes frequent features such as hypospadias and agenesis of the corpus callosum. Thus, SMADIP1, which encodes a transcriptional corepressor of Smad target genes, may play a role not only in the patterning of neural-crest-derived cells and of CNS but also in the development of midline structures in humans.

Abstract
We describe, to our knowledge, the first case of a pulmonary malformation called acinar dysplasia occurring at a surviving fetus after selective embryo reduction in a bichorionic pregnancy. The chronological and histological observations suggest that this anomaly may be linked with a feticide achieved at 13 week's gestation. Literature review concerning selective embryo reduction shows rare cases of vascular connections in bichorionic pregnancies especially during the first half of gestation, that can explain in part the apparition of survivor's anomalies.

Abstract
OBJECTIVE We describe the different ultrasound findings suggestive of trisomy 18. PATIENTS AND METHODS We conducted a retrospective study in 40 cases of trisomy 18 diagnosed in the department of obstetrics at the Lille University Hospital between 1988 and 1998. RESULTS Eighty percent of the women in this series were multiparous. Mean maternal age at discovery of the trisomy as 33.2 years and the mean gestational age was 20.4 weeks. Fifty-five percent of the cases were discovered during the second trimester of pregnancy, 22.5% during the third trimester and 22.5% during the first trimester. One ultrasound abnormality, at least, was detected in 36/40 cases (90%) a percentage that reached 96.8% taking into consideration the ultrasound examinations performed during the second and third trimesters (30/31 cases). The most frequently detected ultrasound abnormalities were: intra uterine growth retardation (IUGR: 50%), poly-hydramnios (42.5%), limb abnormalities (42.5%), cardiac defects (30%), facial abnormalities (37.5%), meningomyelocele (32.5%), digestive abnormalities (32.5%), urinary tract abnormalities (27.5%), lymphangiectasia and cystic hygroma (15%), and single umbilical artery (12.5%). Medical termination of pregnancy (TOP) was performed in 28 cases. There was one spontaneous miscarriage at 8 weeks and one in utero death (IUD) at 39 weeks in a patient who desired to continue her pregnancy. In 6 cases, the issue of the pregnancy was unknown because the patients were lost to follow-up. In 4 cases (10%), pregnancy was continued to delivery of live babies that only survived a few minutes to 7 days. CONCLUSION The ultrasound signs suggestive of trisomy 18 change according to the term of pregnancy. At the first trimester, most of the signs are nonspecific, such as cystic hydroma or lymphangiectasia, and do not suggest the need for a karyotype. At the end of the second trimester, an association of various signs that alone would not be highly suspect suggest the need for further exploration in search of other signs: early IUGR, associated or not with poly-hydramnios, limb abnormalities, cardiac defects, omphalocele, diaphragmatic hernia, meningomyelocele, enlarged cisterna magna, choroid plexus cysts, single umbilical artery, facial dysmorphism, facial cleft, hydronephrosis.

Abstract
Hypophosphatasia is a rare inherited disorder characterized by defective bone mineralization and deficiency of serum and tissue liver/ bone/kidney tissue alkaline phosphatase (L/B/K ALP) activity. We report the characterization of tissue-nonspecific alkaline phosphatase (TNSALP) gene mutations in a series of 9 families affected by severe hypophosphatasia. Fourteen distinct mutations were found, 3 of which were previously reported in the North American or Japanese populations. Seven of the 11 new mutations were missense mutations (M45L, R119H, G145V, C184Y and H154Y, D289V, E459K), the four others were 2 single nucleotide deletions (544delG and 1172delC), a mutation affecting donor splice site (862 + 5A) and a nonsense mutation (R411X).

Abstract
We describe a multiple congenital anomalies (MCA) syndrome dominantly transmitted through three generations. Radial ray abnormalities with wide variability of expression were observed in four female patients. Moreover, a 14-week-gestation male fetus had severe radial ray malformation, anencephaly, unilateral renal agenesis, and a common dorsal mesentery. Results of high-resolution karyotyping were normal in the malformed fetus and his affected mother. Furthermore, several spontaneous abortions of male fetuses had occurred in this pedigree. To our knowledge, a similar association has not been described previously. It could represent a new X-linked dominant MCA syndrome, or an autosomal dominant condition with severe expression limited to males.

Abstract
We describe two female fetuses conceived by a nonconsanguineous couple. The pregnancies were interrupted at 31 and 26 weeks of gestation, respectively, because of severe microcephaly. Postmortem X-ray and autopsy studies showed in both fetuses: 1) severe intrauterine growth retardation; 2) facial anomalies characterized by severe microcephaly, sloping forehead, low set and posteriorly angulated ears, prominent eyes, down-slanting palpebral fissures, large nose, small mouth with full lips, and mild microretrognathia; 3) severe brain hypoplasia that was more pronounced in the second fetus; 4) severe rib hypoplasia with posterior rib-gap defects and in case 2 hypoplasia of several bones (right clavicle, right radius and ulna, several phalanges of hands and feet); 5) contracture at large joints. No other visceral malformations were observed, and chromosomes were normal in patient 2 and parents. This phenotype has some similarities with different syndromic entities but an identical malformation syndrome seems not to have been described previously. Autosomal recessive inheritance is the most likely cause of this putative "new syndrome."

Abstract
We report two cases of prenatal diagnosis of osteogenesis imperfecta (type S of Marotaux), diagnosed at 23 and 24 weeks of gestation, revealed by of an ultrasound scan which noted an abnormal femoral incurvation. The problem of differential diagnosis with other diseases causing femoral incurvation (notably campomelic dysplasia) is difficult, especially at early stage. This question is debated here. The interest to associate ultrasound scan and uterine contents radiography is so demonstrated.

Abstract
BACKGROUND Fetal alcohol syndrome is quite common in our region (incidence: 1/700 live births). It usually associates facial dysmorphism, intra-uterine growth retardation and mental delay. CASE REPORT Jonathan, born to an alcoholic mother, presented a typical dysmorphy of fetal alcohol syndrome and a low inserted umbilicus. A small bowel atresia was discovered at the third day of life and operated on. CONCLUSION Although never been previously described, this association suggests a common embryological origin between fetal alcohol syndrome, small bowel atresia, and umbilical abnormality.

Abstract
BACKGROUND Sodium valproate administration during pregnancy may be teratogenic; it is associated with an increased risk of neural tube defect, tetralogy of Fallot, oral clefting and other facial abnormalities. Knowledge of these harmful effects is still poor. CASE REPORTS Four children, including three siblings, presented with characteristic facial abnormalities (four cases), oral clefting (one case), mental retardation (2/2 cases), and bone anomalies of forearm and hands (one case). The diagnosis of fetal valproate syndrome was only made at the age of 3 1/2 years in the eldest of the three siblings all born from an epileptic mother receiving valproate since the age of 13 years. Prevention advice for further pregnancies was not followed. CONCLUSION All epileptic mothers should be aware of the risk of antiepileptic drugs during pregnancy, specially those given sodium valproate, a potentially teratogenic drug.

Abstract
Thrombocytopenia-absent radius (TAR) syndrome is an autosomal-recessive disorder characterized by a thrombocytopenia and a bilateral radial aplasia with normal thumbs. Only TAR syndrome, out of diseases which may present with radial aplasia, typically has normal thumbs. The prenatal diagnosis is rarely made. We report two observations of TAR syndrome diagnosed in utero in the sibling. The malposition of fetal hands detectable as soon as 11 weeks of gestation requires careful search for longitudinal limb defect of the forearm, especially radial ray defect. The radial aplasia is associated with numerous causes (chromosomal, teratogenic, genetic, multifactorial). The determination of fetal hematologic values revealing a thrombocytopenia allows the prenatal diagnosis of the index case of TAR syndrome.

Abstract
Brachmann-de Lange syndrome (BDLS) is a well-delineated and relatively common syndrome. However, prenatal diagnosis has never been reported, even if in some cases ultrasonography demonstrated one or more manifestations of the syndrome. We report on 3 cases: in the first 2 cases, prenatal ultrasonography demonstrated some signs of the condition. The third represents, to our knowledge, the first prenatal diagnosis of BDLS. We also present a review of the literature concerning pre- and postnatal findings in this syndrome.

Abstract
Intestinal permeability to 51Cr-EDTA was studied in 20 children with cystic fibrosis (CF) and a mean age of 10.7 years, in 7 control adults and in 11 control children. 51Cr-EDTA urinary excretion (mean +/- SD) expressed as a percentage of the orally administered activity was: control children: 1.59 +/- 0.55%, control adults: 1.47 +/- 0.62%, CF patients: 10.7 +/- 8.6%. The difference between CF patients and control children on one hand, between CF patients and control adults on the other hand, was statistically significant (p less than 0.001). Only 3 CF patients had values within the limits of those observed in controls. A statistically significant correlation (p less than 0.01) was observed between the 51Cr-EDTA urinary excretion and steatorrhea. No correlation was found between 51Cr-EDTA urinary excretion and the following parameters: age, sex, weight, height, Shwachman score, liver cirrhosis, oral administration of a mucolytic agent. The eventual, especially nutritional, consequences of this increase of the intestinal permeability in the course of CF remain to be clarified.
