    Cohesin mediates Esco2-dependent transcriptional regulation in zebrafish regenerating fin model of Roberts syndrome.
    Biol Open 2017 Oct 30. Epub 2017 Oct 30.
    Department of Biological Science, Lehigh University, Bethlehem, Pennsylvania, USA
    Robert syndrome (RBS) and Cornelia de Lange syndrome (CdLS) are human developmental disorders characterized by craniofacial deformities, limb malformation, and mental retardation. These birth defects are collectively termed cohesinopathies as both arise from mutations in cohesion genes. CdLS arises due to autosomal dominant mutations or haploinsufficiencies in cohesin subunits (SMC1A, SMC3 and RAD21) or cohesin auxiliary factors (NIPBL and HDAC8) that result in transcriptional dysregulation of developmental programs.

    Syndromic craniosynostosis is a group of multiple conditions with high heterogeneity, and many rare syndromes still remain to be characterized. To identify and analyze causative genetic variants in nine unrelated probands mainly manifested as syndromic craniosynostosis, we reviewed the relevant medical information of the patients and performed the whole exome sequencing, further verified with Sanger sequencing and parental background. Bioinformatics analysis was used to evaluate the potential deleterious or benign effect of each genetic variant through evolutionary conservation alignment, multi-lines of computer predication and the allele frequency in population dataset (control and patient).

    Clinician's guide to genes associated with Rett-like phenotypes - Investigation of a Danish cohort and review of the literature.
    Clin Genet 2017 Oct 10. Epub 2017 Oct 10.
    Applied Human Molecular Genetics, Kennedy Center, Department of Clinical Genetics, Copenhagen University Hospital, Rigshospitalet, Glostrup, Denmark.
    The differential diagnostics in Rett syndrome has evolved with the development of next generation sequencing based techniques and many patients have been diagnosed with other syndromes or variants in newly described genes where the associated phenotype(s) is yet to be fully explored. The term Rett-like refers to phenotypes with distinct overlapping features of Rett syndrome where the clinical criteria are not completely fulfilled. In this paper we have combined a review of Rett-like disorders with data from a Danish cohort of 35 patients with Rett-like phenotypes emphasizing the diagnostic overlap with Pitt-Hopkins syndrome, Cornelia de Lange syndrome with SMC1A variants, and epileptic encephalopathies for example due to STXBP1 variants.

    Congenital Long QT syndrome and torsade de pointes.
    Ann Noninvasive Electrocardiol 2017 Nov 2;22(6). Epub 2017 Jul 2.
    Downstate Medical Center, State University of New York, Brooklyn, NY, USA.
    Since its initial description by Jervell and Lange-Nielsen in 1957, the congenital long QT syndrome (LQTS) has been the most investigated cardiac ion channelopathy. A prolonged QT interval in the surface electrocardiogram is the sine qua non of the LQTS and is a surrogate measure of the ventricular action potential duration (APD). Congenital as well as acquired alterations in certain cardiac ion channels can affect their currents in such a way as to increase the APD and hence the QT interval. Read More

    The coordinated tissue-specific regulation of gene expression is essential for the proper development of all organisms. Mutations in multiple transcriptional regulators cause a group of neurodevelopmental disorders termed "transcriptomopathies" that share core phenotypical features including growth retardation, developmental delay, intellectual disability and facial dysmorphism. Cornelia de Lange syndrome (CdLS) belongs to this class of disorders and is caused by mutations in different subunits or regulators of the cohesin complex. Read More

    Novel findings of left ventricular non-compaction cardiomyopathy, microform cleft lip and poor vision in patient with SMC1A-associated Cornelia de Lange syndrome.

    Hemodynamic monitoring in the critically ill: an overview of current cardiac output monitoring methods.
    F1000Res 2016 16;5. Epub 2016 Dec 16.
    ZNA Stuivenberg, Lange Beeldekensstraat 267, B-2060 Antwerpen, Belgium.
    Critically ill patients are often hemodynamically unstable (or at risk of becoming unstable) owing to hypovolemia, cardiac dysfunction, or alterations of vasomotor function, leading to organ dysfunction, deterioration into multi-organ failure, and eventually death. With hemodynamic monitoring, we aim to guide our medical management so as to prevent or treat organ failure and improve the outcomes of our patients. Therapeutic measures may include fluid resuscitation, vasopressors, or inotropic agents. Read More
