Abstract
UNLABELLED In this study, we investigated the bone cell activity in patients with osteogenesis imperfecta (OI) treated and untreated with neridronate. We demonstrated the key role of Dickkopf-1 (DKK1), receptor activator of nuclear factor-κB ligand (RANKL), and tumor necrosis factor alpha (TNF-α) in regulating bone cell of untreated and treated OI subjects. These cytokines could represent new pharmacological targets for OI. INTRODUCTION Bisphosphonates are widely used in the treatment of children with osteogenesis imperfecta (OI) with the objective of reducing the risk of fractures. Although bisphosphonates increase bone mineral density in OI subjects, the effects on fracture incidence are conflicting. The aim of this study was to investigate the mechanisms underlying bone cell activity in subjects with mild untreated forms of OI and in a group of subjects with severe OI treated with cycles of intravenous neridronate. METHODS Sclerostin, DKK1, TNF-α, RANKL, osteoprotegerin (OPG), and bone turnover markers were quantified in serum of 18 OI patients (12 females, mean age 8.86 ± 3.90), 8 of which were receiving cyclic intravenous neridronate, and 21 sex- and age-matched controls. The effects on osteoblastogenesis and OPG expression of media conditioned by the serum of OI patients and anti-DKK1 neutralizing antibody were evaluated. Osteoclastogenesis was assessed in cultures from patients and controls. RESULTS DKK1 and RANKL levels were significantly increased both in untreated and in treated OI subjects with respect to controls. The serum from patients with high DKK1 levels inhibited both osteoblast differentiation and OPG expression in vitro. High RANKL and low OPG messenger RNA (mRNA) levels were found in lymphomonocytes from patients. High amounts of TNF-α were expressed by monocytes, and an elevated percentage of circulating CD11b-CD51/CD61+ osteoclast precursors was observed in patients. CONCLUSIONS Our study demonstrated the key role of DKK1, RANKL, and TNF-α in regulating bone cell activity of subjects with OI untreated and treated with bisphosphonates. These cytokines could represent new pharmacological targets for OI patients.

Abstract
BACKGROUND Congenital deletions affecting 3q11q23 have rarely been reported and only five cases have been molecularly characterised. Genotype-phenotype correlation has been hampered by the variable sizes and breakpoints of the deletions. In this study, 14 novel patients with deletions in 3q11q23 were investigated and compared with 13 previously reported patients. METHODS Clinical data were collected from 14 novel patients that had been investigated by high resolution microarray techniques. Molecular investigation and updated clinical information of one cytogenetically previously reported patient were also included. RESULTS The molecular investigation identified deletions in the region 3q12.3q21.3 with different boundaries and variable sizes. The smallest studied deletion was 580 kb, located in 3q13.31. Genotype-phenotype comparison in 24 patients sharing this shortest region of overlapping deletion revealed several common major characteristics including significant developmental delay, muscular hypotonia, a high arched palate, and recognisable facial features including a short philtrum and protruding lips. Abnormal genitalia were found in the majority of males, several having micropenis. Finally, a postnatal growth pattern above the mean was apparent. The 580 kb deleted region includes five RefSeq genes and two of them are strong candidate genes for the developmental delay: DRD3 and ZBTB20. CONCLUSION A newly recognised 3q13.31 microdeletion syndrome is delineated which is of diagnostic and prognostic value. Furthermore, two genes are suggested to be responsible for the main phenotype.

Abstract
PURPOSE To describe the genotype and phenotype in a 9-year-old boy with bilateral retinopathy. METHODS The patient, his healthy (by history) nonconsanguineous parents and his sister were examined by best-corrected visual acuity, matrix frequency doubling technology, monocular static field analysis, fundus autofluorescence imaging, optical coherence tomography, Ganzfeld electroretinography (ERG), pattern ERG, multifocal ERG, electro-oculography and genotyping of the BEST1 gene. RESULTS The patient presented with an Arden ratio of 1.25, an unremarkable ERG and fluorescent yellow deposits distributed throughout the fundus suggestive of autosomal recessive bestrophinopathy (ARB). Genotyping revealed a homozygous nonsense mutation in BEST1 (p.R200X). The parents and the sister, who were heterozygous mutation carriers, presented with normal ophthalmological function. CONCLUSIONS ARB is a rare retinal disorder. We contribute a novel patient report indicative of ARB, assessed by clinical examination and confirmed by genotyping of BEST1, to the short list of ARB cases in the literature.

Abstract
Ciliopathies are an expanding group of rare conditions characterized by multiorgan involvement, that are caused by mutations in genes encoding for proteins of the primary cilium or its apparatus. Among these genes, CEP290 bears an intriguing allelic spectrum, being commonly mutated in Joubert syndrome and related disorders (JSRD), Meckel syndrome (MKS), Senior-Loken syndrome and isolated Leber congenital amaurosis (LCA). Although these conditions are recessively inherited, in a subset of patients only one CEP290 mutation could be detected. To assess whether genomic rearrangements involving the CEP290 gene could represent a possible mutational mechanism in these cases, exon dosage analysis on genomic DNA was performed in two groups of CEP290 heterozygous patients, including five JSRD/MKS cases and four LCA, respectively. In one JSRD patient, we identified a large heterozygous deletion encompassing CEP290 C-terminus that resulted in marked reduction of mRNA expression. No copy number alterations were identified in the remaining probands. The present work expands the CEP290 genotypic spectrum to include multiexon deletions. Although this mechanism does not appear to be frequent, screening for genomic rearrangements should be considered in patients in whom a single CEP290 mutated allele was identified.

Abstract
OBJECTIVE Aim of this study is to report on basal clinical phenotype and follow up after diagnosis, of patients with 17beta-hydroxysteroid-dehydrogenase type 3 (17beta-HSD3) deficiency in Italy. SETTING Pediatric Endocrine Departments, University Hospitals. PATIENTS The cases of 5 Italian subjects affected by 17beta-HSD3 deficiency are presented in this study. INTERVENTIONS Laboratory and genetic assessment. Gonadectomy and female sex assignment (4 patients) or GnRH analog therapy to regress puberty and gender identity disorder (1 patient). RESULTS Presentation lasted from pregnancy (pre-natal diagnosis of a 46,XY fetus with female external genitalia) to infancy (inguinal hernia containing testes/clitoromegaly) and adolescence (virilisation). All subjects but one (subject 1, Central-Northern Italy) were from small areas of Southern Italy. Endocrine data (baseline and/or stimulated testosterone/ Delta4-androstenedione ratio) were informative. Two girls were homozygous for 17beta-HSD3 gene mutations (G289S/G289S; R80W/R80W), while the others were compound heterozygous (IVS325+4 A>T/A203V; L212Q/M235V; R80W/A235E). Four patients were confirmed as females and were well-adjusted with assigned sex; gender identity disorder improved during treatment with GnRH analog in the last subject. CONCLUSIONS 17betaHSD3 deficiency may present from pregnancy to puberty for different clinical issues. Albeit testosterone/Delta4-androstenedione ratio represents the most accurate endocrine marker to diagnose the disorder, hCGstimulation is mandatory in pre-puberty. Molecular analysis of 17beta-HSD3 gene should be performed to confirm the diagnosis. Temporary GnRH analog treatment may regress gender identity disorder and provide time to confirm or change the birth sex assignment. Female individuals seems to be compliant with their sex, providing that virilisation does not occur. In Italy, the disorder seems to be more prevalent in the Southern regions and shows genetic heterogeneity.

Abstract
Using array comparative genome hybridisation (CGH) 41 de novo reciprocal translocations and 18 de novo complex chromosome rearrangements (CCRs) were screened. All cases had been interpreted as "balanced" by conventional cytogenetics. In all, 27 cases of reciprocal translocations were detected in patients with an abnormal phenotype, and after array CGH analysis, 11 were found to be unbalanced. Thus 40% (11 of 27) of patients with a "chromosomal phenotype" and an apparently balanced translocation were in fact unbalanced, and 18% (5 of 27) of the reciprocal translocations were instead complex rearrangements with >3 breakpoints. Fourteen fetuses with de novo, apparently balanced translocations, all but two with normal ultrasound findings, were also analysed and all were found to be normal using array CGH. Thirteen CCRs were detected in patients with abnormal phenotypes, two in women who had experienced repeated spontaneous abortions and three in fetuses. Sixteen patients were found to have unbalanced mutations, with up to 4 deletions. These results suggest that genome-wide array CGH may be advisable in all carriers of "balanced" CCRs. The parental origin of the deletions was investigated in 5 reciprocal translocations and 11 CCRs; all were found to be paternal. Using customized platforms in seven cases of CCRs, the deletion breakpoints were narrowed down to regions of a few hundred base pairs in length. No susceptibility motifs were associated with the imbalances. These results show that the phenotypic abnormalities of apparently balanced de novo CCRs are mainly due to cryptic deletions and that spermatogenesis is more prone to generate multiple chaotic chromosome imbalances and reciprocal translocations than oogenesis.

Abstract
Sotos syndrome is characterized by pre- and post-natal overgrowth, typical craniofacial features, advanced bone age, and developmental delay. Some degree of phenotypic overlap exists with other overgrowth syndromes, in particular with Weaver syndrome. Sotos syndrome is caused by haploinsufficiency of the NSD1 (nuclear receptor SET domain containing gene 1) gene. Microdeletions involving the gene are the major cause of the syndrome in Japanese patients, whereas intragenic mutations are more frequent in non-Japanese patients. NSD1 aberrations have also been described in some patients diagnosed as Weaver syndrome. Some authors have suggested a certain degree of genotype-phenotype correlation, with a milder degree of overgrowth, a more severe mental retardation, and a higher frequency of congenital anomalies in microdeleted patients. Data on larger series are needed to confirm this suggestion. We report here on microdeletion and mutation analysis of NSD1 in 59 patients with congenital overgrowth. Fourteen novel mutations, two previously described and one microdeletion were identified. All patients with a NSD1 mutation had been clinically classified as "classical Sotos," although their phenotype analysis demonstrated that some major criteria, such as overgrowth and macrocephaly, could be absent. All patients with confirmed mutations shared the typical Sotos facial gestalt. A high frequency of congenital heart defects was present in patients with intragenic mutations, supporting the relevance of the NSD1 gene in the pathogenesis of this particular defect.

Abstract
In this study, we report the combined use of whole and partial chromosome 6 painting probe and YACS probes to define the unbalanced region of a de novo 6q+ marker chromosome. A male patient with peculiar features of << distal 6q trisomy syndrome >> showed a direct duplication of 6q23 region. Comparing the phenotype of this child with the phenotype of other << de novo >> partial 6q trisomy, we conclude that band 6q23 has an important role in defining 6q trisomy.

Abstract
Developmental anomalies of the appendicular skeleton are among the most common and easily ascertained birth defects. Split hand/split foot malformations, distinctive in having deficiency of the central rays, occur as isolated anomalies and as one component of multisystem syndromes. The clinical and molecular characterization of a new syndrome, found in two unrelated families, consisting of split foot with hearing loss, is presented here. As in other split hand/split foot conditions, variable expression and reduced penetrance is notable. In the larger family, variably expressed split foot malformations were found in 6 of 11 gene carriers. and mild-to-moderate sensorineural hearing loss in 4. Split hand and cleft lip/palate in one individual and tibial deficiency in another suggest that these malformations are uncommon components of the syndrome. Ectodermal abnormalities did not occur. In the second family, variable split foot was observed in 3 of 4 gene carriers, and sensorineural deafness was present in 3. Split hand was only seen in a gene carrier who also had split foot and deafness. One gene carrier only had deafness. The gene for split hand split foot with sensorineural hearing loss was linked to markers in 7q21 in both families, with a combined (maximum LOD score of 4.37 at theta = 0.0 for locus D7S527) at 80% penetrance. Efforts to identify the responsible gene have not yet been successful.

Abstract
BACKGROUND The presence of a spermatogenesis locus (gene or gene complex) in the euchromatic region of the long arm of the Y chromosome (Yq11), defined as azoospermia factor on the basis of gross structural rearrangement, was detected. The gene family responsible for different spermatogenetic defects is "deleted in azoospermia" (DAZ). CASE A 34-year-old man had oligozoospermia, and a cytogenetic analysis carried out on peripheral lymphocytes with G banding revealed a 46,X, inv(Y)(p11q11)karyotype. The relation between the chromosomal breakpoint and the DAZ gene was more precisely defined by a fluorescent in situ hybridization technique. We revealed two signals for the DAZ gene, weaker than normal, one on the short arm and the other on the long arm of the Y chromosome, indicating that the breakpoint was located at the DAZ gene level. CONCLUSION This is the first report documenting a chromosomal pericentric inversion with disruption in the DAZ gene area. We hope to obtain information on whether the disruption affects a functional zone of the gene and correlates with oligospermia at the chromosomal level.

Abstract
Twelve patients with different features of Turner syndrome, and with Xp and Yp rearrangements involving the pseudoautosomal region (PAR1) are described. In all patients, FISH analysis showed loss of one copy of the Short Stature Homeobox (SHOX)-containing gene. Ten patients had short stature and one disproportionate (mesomelic) normal stature, while the last one had normal stature. Skeletal abnormalities, including shortened ulna, were detected in nine subjects, and in six of them Madelung deformity was observed. These clinical data indicated a genotype phenotype correlation between haploinsufficiency of SHOX, and short stature and skeletal abnormalities.

Abstract
BACKGROUND There are only a few reports on ovulation induction in women with premature ovarian failure resulting from an X chromosome abnormality. Up to now, there have been no publications on ovulation stimulation in a patient with an X-autosome translocation. CASE A healthy, 29-year-old woman had premature ovarian failure (POF) but no other discernible pathologic clinical features. Laboratory tests prior to initiating a stimulation cycle revealed a 46,XX t(X;16) karyotype. Genetic counseling was proposed, and the risk of X chromosome abnormality was discussed. The couple decided to undergo ovulation induction. For treatment of infertility, clomiphene citrate had been administered in the past. Because those treatments were not successful, GnRH-a and follicle stimulating hormone treatment was recommended. The first treatment cycle was successful in inducing ovulation, but on the 15th day after human chorionic gonadotropin administration, menstruation occurred. The couple refused a second stimulation, and menstruation occurred 32 days after the first. The patient then became amenorrheic again. CONCLUSION At least some hope can be offered to infertile women with hypergonadotropinism and X-autosomal translocation, although it is impossible to determine whether ovulation induction will result in pregnancy. New treatments can be anticipated for women with POF and X chromosome aberrations who have similar hormonal environments.

Abstract
An X/Y translocation associated with Leri-Weill dyschondrosteosis (LWD) was detected in a boy and in his mother. FISH analysis with specific probes for SHOX and SRY displayed no signal on the der(X), while one signal for SHOX was detected on the normal X chromosome in the mother, and one signal each for SHOX and SRY was detected on the normal Y chromosome in the proband.

Abstract
OBJECTIVE To investigate the incidence of chromosomal aberration in men and women in an intracytoplasmic sperm injection (ICSI) program for severe male infertility as well as in conceptuses resulting from these ICSI treatments. STUDY DESIGN We evaluated chromosomal analysis, outcome of ICSI and the conceptuses resulting from treatment of 301 couples included in ICSI program. RESULTS Cytogenetic evaluation demonstrated structural anomalies in 11 cases (3.6%), 9 men (2.9%) and 2 women (0.7%), all consisting of balanced chromosomal translocations. There were no significant differences in the rates of developed embryos (44.2% versus 40.1%) in couples with abnormal (n = 11) and normal (n = 290) chromosomal analysis. Embryo transfer led to a similar number of newborns (15.3% versus 12.4%) per transferred embryos, without any correlation with parents' chromosomes. In 63 fetuses conceived from couples without chromosomal abnormalities, we observed one fetus affected by Patau syndrome (47,XY, + 13). Two of four (50%) fetuses conceived by couples with male balanced chromosomal defects were carriers of the chromosomal translocation inherited from their fathers. The two fetuses resulted in the birth of two infants observed to be normal at the 12-month pediatric follow-up. CONCLUSION The offer of this treatment to infertile couples with male factor infertility should be accompanied by proper information regarding the genetic risks of this treatment. ICSI remains a good therapeutic option for infertile patients, but prenatal diagnosis is mandatory because of the potential increased aneusomic risk for the offspring conceived.

Abstract
Pseudodiastrophic dysplasia is a distinct disorder that differs from diastrophic dysplasia on the basis of elbow and proximal interphalangeal joint dislocations, platyspondyly, and scoliosis. We report on a new patient with this rare skeletal dysplasia and two previously undescribed major malformations: omphalocele and complex heart defect.
