The Tecan SiLA2 SDK: A royalty-free, open-source framework to develop SiLA2 servers and clients.

Many devices in a laboratory only have proprietary interfaces. Integrating them into an automation platform such as a Robotic Liquid Handler (RLH) thus usually requires upfront technical configuration and often dedicated software development. In this paper, we present the Tecan SiLA2 SDK, a BSD-3 licensed, royalty-free open-source framework on the.

Connecting Artificial Brains to Robots in a Comprehensive Simulation Framework: The Neurorobotics Platform.

Combined efforts in the fields of neuroscience, computer science, and biology allowed to design biologically realistic models of the brain based on spiking neural networks. For a proper validation of these models, an embodiment in a dynamic and rich sensory environment, where the model is exposed to a realistic sensory-motor task, is needed. Due to the complexity of these brain models that, at the current stage, cannot deal with real-time constraints, it is not possible to embed them into a real-world task.

Long-range conserved non-coding SHOX sequences regulate expression in developing chicken limb and are associated with short stature phenotypes in human patients.

Defects in long-range regulatory elements have recently emerged as previously underestimated factors in the genesis of human congenital disorders. Léri-Weill dyschondrosteosis is a dominant skeletal malformation syndrome caused by mutations in the short stature homeobox gene SHOX. We have analysed four families with Léri-Weill dyschondrosteosis with deletions in the pseudoautosomal region but still with an intact SHOX coding region.

Novel mutations in BCOR in three patients with oculo-facio-cardio-dental syndrome, but none in Lenz microphthalmia syndrome.

Oculo-facio-cardio-dental (OFCD) syndrome is a rare X-linked dominant condition with male lethality characterized by microphthalmia, congenital cataracts, facial dysmorphic features, congenital heart defects, and dental anomalies. Mutations in BCOR (BCL6 co-repressor) located in Xp11.4 have been described to cause OFCD syndrome.

[Surgical therapy of cone-shaped epiphyses of the proximal interphalangeal joints in tricho-rhino-phalangeal syndrome type I: a survey among three successive generations of a single family].

Report on 6 individuals, occurring in three successive generations of a single family, who were affected by "classical" tricho-rhino-phalangeal syndrome type I. Besides pear-shaped noses, enlarged philtrum, hypotrichosis, premature alopecia, coned epiphysis at the proximal interphaleangeal joints with consecutive ulnar deviation of the long fingers, dysostotic feet, Perthes-like hip dysplasia with multilocated joint laxity and hyposomia were impressing. Height was 168 cm, corresponding to the 50 (th) percentile.

Genotyping in 46 patients with tentative diagnosis of Treacher Collins syndrome revealed unexpected phenotypic variation.

To define the range of phenotypic expression in Treacher Collins syndrome (TCS; Franceschetti-Klein syndrome), we performed mutation analysis in the TCOF1 gene in 46 patients with tentative diagnosis of TCS and evaluated the clinical data, including a scoring system. A total of 27 coding exons of TCOF1 and adjacent splice junctions were analysed by direct sequencing. In 36 patients with a clinically unequivocal diagnosis of TCS, we detected 28 pathogenic mutations, including 25 novel alterations.

Subtelomere FISH in 50 children with mental retardation and minor anomalies, identified by a checklist, detects 10 rearrangements including a de novo balanced translocation of chromosomes 17p13.3 and 20q13.33.

Submicroscopic or subtle aneusomies at the chromosome ends, typically diagnosed by subtelomere fluorescence in situ hybridization (FISH), are a significant cause of idiopathic mental retardation (MR). Some 20 subtelomere studies, including more than 2,500 subjects, have been reported. The studies are not directly comparable because different techniques and patient ascertainment criteria were used, but an analysis of 14 studies showed that aberrations were detected in 97 out of 1,718 patients (5.

Minimal clinical expression of the holoprosencephaly spectrum and of Currarino syndrome due to different cytogenetic rearrangements deleting the Sonic Hedgehog gene and the HLXB9 gene at 7q36.3.

We report clinical, cytogenetic, and molecular cytogenetic studies on four patients with subtle or submicroscopic 7q36 deletions either of de novo origin or resulting from a cryptic parental translocation. Fluorescence in situ hybridization (FISH) studies indicated that in all four patients, the Sonic Hedgehog gene (SHH) and the homeobox gene HLXB9, among others, are comprised in the deletions. Besides mental retardation and short stature, all patients showed only minimal manifestations of the holoprosencephaly (HPE) spectrum and only one displayed symptoms of the Currarino syndrome.

Jejunal atresia related to the use of toluidine blue in genetic amniocentesis in twins.

Since 1990 avoidance of methylene blue as a dye in diagnostic amniocentesis is recommended. This is the result of the observation that a high incidence of jejuno-ileal atresia appeared in twin pregnancies following intraamniotic injection of methylene blue. We report a case of jejunal atresia in twins after injection of toluidine blue.

Spectrum of mutations in PTPN11 and genotype-phenotype correlation in 96 patients with Noonan syndrome and five patients with cardio-facio-cutaneous syndrome.

Noonan syndrome (NS) is a relatively common, but genetically heterogeneous autosomal dominant malformation syndrome. Characteristic features are proportionate short stature, dysmorphic face, and congenital heart defects. Only recently, a gene involved in NS could be identified.

Familial MCA/MR syndrome due to inherited submicroscopic translocation t(18;21)(q22.1q21.3) with breakpoint at the Down syndrome critical region.

We report three generation family that includes two patients with severe mental retardation and additional anomalies who have been studied, clinically, cytogenetically, and molecular cytogenetically. A clinical diagnosis could not be made in the propositus, but facial anomalies of Down syndrome (DS) were recognized in the maternal uncle of the propositus. In view of a strong family history of recurrent miscarriage, a familial translocation was highly suggestive.

Classic, atypically severe and neonatal Marfan syndrome: twelve mutations and genotype-phenotype correlations in FBN1 exons 24-40.

Mutations in the gene for fibrillin-1 (FBN1) cause Marfan syndrome, an autosomal dominant disorder of connective tissue with prominent manifestations in the skeletal, ocular, and cardiovascular system. There is a remarkable degree of clinical variability both within and between families with Marfan syndrome as well as in individuals with related disorders of connective tissue caused by FBN1 mutations and collectively termed type-1 fibrillinopathies. The so-called neonatal region in FBN1 exons 24-32 comprises one of the few generally accepted genotype-phenotype correlations described to date.

Genotypic and phenotypic spectrum in tricho-rhino-phalangeal syndrome types I and III.

Tricho-rhino-phalangeal syndrome (TRPS) is characterized by craniofacial and skeletal abnormalities. Three subtypes have been described: TRPS I, caused by mutations in the TRPS1 gene on chromosome 8; TRPS II, a microdeletion syndrome affecting the TRPS1 and EXT1 genes; and TRPS III, a form with severe brachydactyly, due to short metacarpals, and severe short stature, but without exostoses. To investigate whether TRPS III is caused by TRPS1 mutations and to establish a genotype-phenotype correlation in TRPS, we performed extensive mutation analysis and evaluated the height and degree of brachydactyly in patients with TRPS I or TRPS III.

FISH studies in 45 patients with Rubinstein-Taybi syndrome: deletions associated with polysplenia, hypoplastic left heart and death in infancy.

Rubinstein-Taybi syndrome (RTS) is a dominant Mendelian disorder characterised by mental retardation, a typical facies, broad thumbs and short stature. Previous reports indicated that 4-25% of RTS patients have a submicroscopic 16p13.3 deletion of the CBP gene.

Calcium metabolism and growth during early treatment of children with X-linked hypophosphataemic rickets.

Unlabelled: To evaluate the effect of early treatment on calcium metabolism and growth of infants with X-linked hypophosphataemic rickets (XLH), we enrolled eight infants (one boy) with XLH in a prospective study before and during combined treatment with 40 60 mg/kg per day phosphate and 20-40 ng/kg per day 1,25(OH)2D3 (calcitriol). The duration of treatment ranged from 12 to 68 months (median 27 months). We measured the height and several indices of calcium and bone metabolism before and at intervals of 6 weeks to 3 months thereafter during treatment.

Deletion mapping by FISH with BACs in patients with partial monosomy 22q13.

Patients with deletions in 22q13 are known to have phenotypic features that include normal or accelerated growth, large hands and feet, hypotonia, delayed psychomotor development and mild facial dysmorphism. To date, very few cases have been investigated by detailed molecular genetic analysis. We have analyzed three new patients with terminal deletions in 22q.

A large family with subtelomeric translocation t(18;21)(q23;q22.1) and molecular breakpoint in the Down syndrome critical region.

We describe a 17-month-old infant with clinical features of Down syndrome and a normal karyotype by standard chromosomal analysis, her two uncles aged 28 and 30 years, respectively, with reduced intelligence and unusual appearance but not apparent Down syndrome, and a severely retarded 6-year-old girl with dysmorphy and epilepsy from the same family. Cytogenetic studies of patients and normal intervening relatives had been carried out at different institutions with normal results. Fluorescence in situ hybridization using whole chromosome painting and unique-copy probes (cosmids) and high-resolution banding revealed a familial subtelomeric translocation of chromosomes 18 and 21, resulting in partial trisomy 21 in the infant and her two uncles, and partial monosomy 21 in the 6-year-old girl.

A small deletion of 16q23.1-->16q24.2 [del(16)(q23.1q24.2).ish del(16)(q23.1q24.2)(D16S395+, D16S348-, P5432+)] in a boy with iris coloboma and minor anomalies.

We report on a 5-year-old boy with bilateral coloboma of iris, short stature, moderate developmental delay, and a few minor craniofacial anomalies. High-resolution GTG banding showed a small distal deletion of one chromosome 16 [del(16)(q23.1q24.

Evidence for a critical region for penoscrotal inversion, hypospadias, and imperforate anus within chromosomal region 13q32.2q34.

Two unrelated patients with small distal deletions of the long arm of chromosome 13 are described, with shawl scrotum and penoscrotal transposition, penoscrotal hypospadias, a reduced perineum, and anal atresia. The patients have small deletions of 13(q32.2qter) and 13(q32q34), respectively.

Delineation of a contiguous gene syndrome with multiple exostoses, enlarged parietal foramina, craniofacial dysostosis, and mental retardation, caused by deletions in the short arm of chromosome 11.

A contiguous gene syndrome due to deletions of the proximal short arm of chromosome 11 is described in eight patients belonging to four families. The main clinical features are multiple exostoses, enlarged parietal foramina, craniofacial dysostosis, and mental retardation. The patients have cytogenetic and/or molecular deletions of chromosome 11p11-p13.

Pseudohypoaldosteronism: family studies to identify asymptomatic carriers by stimulation of the renin-aldosterone system.

Defective aldosterone receptor binding is present in pseudohypoaldosteronism, and sporadic as well as familial cases have been reported. In familial pseudohypoaldosteronism, autosomal dominant as well as autosomal recessive inheritance has been described. The autosomal dominant form is characterized by a relative mild course of the disease and asymptomatic carriers of the defect in these families, whereas the autosomal recessive form is characterized by severe salt-losing symptoms; not uncommonly these families are consanguineous.

[Contribution of the ophthalmologist to presymptomatic diagnosis of familial adenomatous polyposis (FAP)].

Familial adenomatous polyposis (FAP) represents a hereditary precancerous condition. Symptoms often appear malignant transformation only. For persons at risk early recognition of gene carriers is essential.

DNA, FISH and complementation studies in ICF syndrome: DNA hypomethylation of repetitive and single copy loci and evidence for a trans acting factor.

ICF syndrome (ICFS) is a rare immunodeficiency disorder characterized by instability of the pericentromeric heterochromatin predominantly of chromosomes 1 and 16. DNA methylation studies in two unrelated ICFS patients provide further evidence for a marked hypomethylation of satellite 2 DNA. The ICFS-specific disturbances of chromatin structure take place within the satellite 2 DNA regions, as demonstrated by fluorescence in situ hybridization analysis.

Familial pseudohypoaldosteronism: a review on the heterogeneity of the syndrome.

Pseudohypoaldosteronism is thought to be a rare salt-losing disorder, caused by resistance to the action of aldosterone. Defective aldosterone receptor binding is present in familial as well as sporadic cases and it has been suggested that the pathogenesis is due to a defect in the aldosterone receptor system. To date, however, molecular genetic analysis has been unable to identify a mutation in the aldosterone receptor gene itself.
