  • 3D protein modelling of the human AFF3 degron region bound to SIAH ubiquitin ligase

    Variant-specific pathophysiological mechanisms of AFF3 differently influence transcriptome profiles

    Background

    We previously described the KINSSHIP syndrome, an autosomal dominant disorder associated with intellectual disability (ID), mesomelic dysplasia and horseshoe kidney, caused by de novo variants in the degron of AFF3. Mouse knock-ins and overexpression in zebrafish provided evidence for a dominant-negative mode of action, wherein an increased level of AFF3 resulted in pathological effects.

  • De novo variants in ATXN7L3 lead to developmental delay, hypotonia and distinctive facial features

    Deubiquitination is critical for the proper functioning of numerous biological pathways such as DNA repair, cell cycle progression, transcription, signal transduction, and autophagy. Accordingly, pathogenic variants in deubiquitinating enzymes (DUBs) have been implicated in neurodevelopmental disorders (ND) and congenital abnormalities. ATXN7L3 is a component of the DUB module of the SAGA complex, and two other related DUB modules, and serves as an obligate adaptor protein of 3 ubiquitin-specific proteases (USP22, USP27X or USP51).

    Astrogliosis and Neuroinflammation Underlie Scoliosis Upon Cilia Dysfunction

    Cilia defects lead to scoliosis in zebrafish, but the underlying pathogenic mechanisms are poorly understood and may diverge depending on the mutated gene.

    Missense variants in ANO4 cause sporadic encephalopathic or familial epilepsy with evidence for a dominant-negative effect

    Anoctamins are a family of Ca2+-activated proteins that may act as ion channels and/or phospholipid scramblases with limited understanding of function and disease association. Here, we identified five de novo and two inherited missense variants in ANO4 (alias TMEM16D) as a cause of fever-sensitive developmental and epileptic or epileptic encephalopathy (DEE/EE) and generalized epilepsy with febrile seizures plus (GEFS+) or temporal lobe epilepsy.

    DPF2-related Coffin-Siris syndrome type 7 in two generations

    To date 11 patients with Coffin-Siris syndrome type 7 (OMIM 618027) have been described since the first literature report. All reported patients carried de novo variants with presumed dominant negative effect, which localized in the PHD1/PHD2 domains of DPF2.

    Systematic identification of structure-specific protein–protein interactions

    The physical interactome of a protein can be altered upon perturbation, modulating cell physiology and contributing to disease. Identifying interactome differences of normal and disease states of proteins could help understand disease mechanisms, but current methods do not pinpoint structure-specific PPIs and interaction interfaces proteome-wide.

    Olfactory Receptor OR2K2 Expression in Human Choroid Plexus as a Potential Marker in Early Sporadic Alzheimer’s Disease

    Epithelial cells comprising the choroid plexus (CP) form a crucial barrier between the blood
    and the cerebrospinal fluid, thereby assuming a central position in brain homeostasis and signaling.
    Mounting evidence suggests that the impairment of CP function may be a significant contributor to
    Alzheimer’s disease (AD) pathogenesis.

  • SNUPN deficiency causes a recessive muscular dystrophy due to RNA mis-splicing and ECM dysregulation

    SNURPORTIN-1, encoded by SNUPN, plays a central role in the nuclear import of spliceosomal small nuclear ribonucleoproteins. However, its physiological function remains unexplored. In this study, we investigate 18 children from 15 unrelated families who present with atypical muscular dystrophy and neurological defects.

  • Astrogliosis and Neuroinflammation Underlie Scoliosis Upon Cilia Dysfunction

    Cilia defects lead to scoliosis in zebrafish, but the underlying pathogenic mechanisms are poorly understood and may diverge depending on the mutated gene. We dissected the mechanisms of scoliosis onset in a zebrafish mutant for the rpgrip1l gene encoding a ciliary transition zone protein. rpgrip1l mutant fish developed scoliosis with near-total penetrance but asynchronous onset in juveniles.

    Shared and unique consequences of Joubert Syndrome gene dysfunction on the zebrafish central nervous system

    Joubert Syndrome (JBTS) is a neurodevelopmental ciliopathy defined by a highly specific midbrain-hindbrain malformation, variably associated with additional neurological features. JBTS displays prominent genetic heterogeneity with >40 causative genes that encode proteins localising to the primary cilium, a sensory organelle that is essential for transduction of signalling pathways during neurodevelopment, among other vital functions.

    Historic characteristics and mortality of patients in the Swiss Amyloidosis Registry

    Systemic amyloidoses are rare protein-folding diseases with heterogeneous, often nonspecific clinical presentations. To better understand systemic amyloidoses and to apply state-of-the-art diagnostic pathways and treatment, the interdisciplinary Amyloidosis Network was founded in 2013 at University Hospital Zurich. In this respect, a registry was implemented to study the characteristics and life expectancy of patients with amyloidosis within the area covered by the network. Patient data were collected retrospectively for the period 2005–2014 and prospectively from 2015 onwards.
