Cornelia de Lange Syndrome (CdLS) is a very rare syndrome characterised by multiple congenital anomaly affecting various organs and severe mental retardation. Incidence has been reported to be 1: 10.000-20.000 among the general population, with no racial predilection. The aetiology is still unknown but researchers, in 2004, discovered a mutation of the NIPBL gene located on chromosome 5 which i...

PDS5B is a sister chromatid cohesion protein that is crucial for faithful segregation of duplicated chromosomes in lower organisms. Mutations in cohesion proteins are associated with the developmental disorder Cornelia de Lange syndrome (CdLS) in humans. To delineate the physiological roles of PDS5B in mammals, we generated mice lacking PDS5B (APRIN). Pds5B-deficient mice died shortly after bir...

PURPOSE Cornelia de Lange (CdLS) syndrome is characterized by multiple congenital anomalies and mental retardation. Epilepsy is a clinical feature found in about 20% of cases, but there are no data about its electroclinical features and long-term outcome. METHODS we describe a clinical series of fourteen Caucasian CdLS paediatric patients who developed epilepsy, with special reference to the ...

BACKGROUND Cornelia de Lange syndrome (CdLS) is a multiple congenital anomaly syndrome characterised by a distinctive facial appearance, prenatal and postnatal growth deficiency, psychomotor delay, behavioural problems, and malformations of the upper extremities. Recently mutations in NIPBL, the human homologue of the Drosophila Nipped-B gene, were found to cause CdLS. Mutations have been found...

Abstract. After the successful launch of Aeolus, which is first spaceborne wind lidar developed by European Space Agency (ESA), on 22 August 2018, we deployed several ground-based coherent Doppler lidars (CDLs) to verify observations from Aeolus. By simultaneous measurements with CDLs at 17 stations over China, Rayleigh-clear and Mie-cloudy horizontal-line-of-sight (HLOS) velocities Aeolus in a...

Cornelia de Lange Syndrome (CdLS) is a choesinopathy: a severe genetic disorder caused by mutations in the cohesin complex genes. The phenotype is characterized by typical facial dysmorphism, growth impairment and multiorgan abnormalities including brain alterations. Wnt pathway is known to play a fundamental role in central nervous system development and it has been shown that Wnt pathway is d...

Vertebrates have two cohesin complexes that consist of Smc1, Smc3, Rad21/Scc1 and either SA1 or SA2, but their functional specificity is unclear. Mouse embryos lacking SA1 show developmental delay and die before birth. Comparison of the genome-wide distribution of cohesin in wild-type and SA1-null cells reveals that SA1 is largely responsible for cohesin accumulation at promoters and at sites b...

Anxiety disorders are heightened in specific genetic syndromes in comparison to intellectual disability of heterogeneous aetiology. In this study, we described and contrasted anxiety symptomatology in fragile X (FXS), Cornelia de Lange (CdLS) and Rubinstein-Taybi syndromes (RTS), and compared the symptomatology to normative data for typically-developing children and children diagnosed with an a...

Mutations in NIPBL are the most frequent cause of Cornelia de Lange syndrome (CdLS), a developmental disorder encompassing several neurological defects, including intellectual disability and seizures. How NIPBL mutations affect brain development is not understood. Here we identify Nipbl as a functional interaction partner of the neural transcription factor Zfp609 in brain development. Depletion...

Abnormal epigenetic regulation can cause the nervous system to develop abnormally. Here, we sought to understand the mechanism by which this occurs by investigating the protein complex cohesin, which is considered to regulate gene expression and, when defective, is associated with higher-level brain dysfunction and the developmental disorder Cornelia de Lange syndrome (CdLS). We generated condi...
