  • Bardet-Biedl syndrome: The longer we miss, the worse is the outcome
    CONCLUSION: The characteristics of BBS should be noted by doctors because an early diagnosis will result in a better outcome. The case was prone to numerous consequences due to the delay in diagnosis, which could have been avoided if an early diagnosis had been established.
  • Hereditary thrombotic thrombocytopenic purpura (TTP) with co-occurring autosomal dominant polycystic kidney disease (ADPKD)
    Hereditary thrombotic thrombocytopenic purpura (TTP) and autosomal dominant polycystic kidney disease (ADPKD) are two distinct genetic diseases that may affect the kidneys through different mechanisms. ADPKD is a common genetic disorder that leads to exponential formation and growth of cysts replacing all segments of nephrons. Hereditary TTP is a rare autosomal recessive disorder that leads to the disseminated formation of arteriolar platelet-rich thrombi, which produce manifestations of various...
  • Composition, organization and mechanisms of the transition zone, a gate for the cilium
    The cilium evolved to provide the ancestral eukaryote with the ability to move and sense its environment. Acquiring these functions required the compartmentalization of a dynein-based motility apparatus and signaling proteins within a discrete subcellular organelle contiguous with the cytosol. Here, we explore the potential molecular mechanisms for how the proximal-most region of the cilium, termed transition zone (TZ), acts as a diffusion barrier for both membrane and soluble proteins and helps...
  • Tissue-specific requirement of sodium channel and clathrin linker 1 (Sclt1) for ciliogenesis during limb development
    Primary cilia have essential roles as signaling centers during development and adult homeostasis. Disruption of ciliary structure or function causes congenital human disorders called ciliopathies. Centriolar distal appendage (DAP) proteins are important for anchoring cilia to the membrane. However, the exact functions of DAP during in vivo ciliogenesis and animal development remain poorly understood. Here, we showed that the DAP component sodium channel and clathrin linker 1 (Sclt1) mutant mice...
  • Prenatal diagnosis of Bardet Biedl Syndrome: A case report
    The Bardet-Biedl Syndrome (BBS), also called Laurence-Moon-Bardet-Biedl syndrome is a rare ciliopathic autosomal recessive genetic defect. BBS phenotype develops over the years and diagnosis is usually made in late childhood or early adulthood. Prenatal diagnosis is rare in absence of family history or consanguinity. The major features of this syndrome are cone-rod dystrophy, obesity, polydactyly, learning disabilities, hypogonadism in males, renal anomalies, nystagmus, speech disorders,...
  • Von Hippel-Lindau syndrome with a rare complication of dilated cardiomyopathy: a case report
    CONCLUSION: Cardiac involvement is an atypical manifestation in VHL syndrome. Early diagnosis with genetic screening is essential for avoiding life-threatening complications associated with VHL. The management of this rare manifestation of VHL syndrome requires further investigation.
  • Novel mutation of IFT140 in an infant with Mainzer-Saldino syndrome presenting with retinal dystrophy
    A seven-month-old girl presented with bilateral roving nystagmus, hyperopia, and retinal dystrophy, and was brought to our ophthalmology clinic. Visual-evoked potentials (VEPs) were non-recordable in both the eyes. No other systemic symptoms or abnormalities were observed. Whole exome sequencing (WES) identified a compound heterozygous mutation in the IFT140 gene: c.1990G > A (p. Glu664Lys) and c.2214_2217del (p.Asp738GlufsTer47). The genetic results support a diagnosis of Mainzer-Saldino...

  • Diagnosis and genetic analysis of a case with Bardet-Biedl syndrome caused by compound heterozygous mutations in the BBS12 gene
    Bardet-Biedl syndrome (BBS) is a rare autosomal recessive ciliopathy, which is caused by mutations mainly in genes encoding BBSome complex and IFT complex. Here, we reported a 21-year-old female with BBS characterized by three primary features including obesity, retinitis pigmentosa sine pigmento and bilateral renal cysts. She also had some secondary features such as diabetes mellitus, nonalcoholic fatty liver disease, subclinical hypothyroidism and mild conductive hearing damage. Whole exome...
  • Von Hipple-Lindau disease complicated with central retinal vein occlusion: a case report
    CONCLUSIONS: This is a rare case of polycythemia complicated by CRVO in patient with VHL disease. It reminds us that the systemic disease factors should be fully considered in the diagnosis of young patients with CRVO, and that treatment requires a coordinated effort of physicians.
  • Mitochondrial dysfunction compromises ciliary homeostasis in astrocytes
    Astrocytes, often considered as secondary responders to neurodegeneration, are emerging as primary drivers of brain disease. Here we show that mitochondrial DNA depletion in astrocytes affects their primary cilium, the signaling organelle of a cell. The progressive oxidative phosphorylation deficiency in astrocytes induces FOXJ1 and RFX transcription factors, known as master regulators of motile ciliogenesis. Consequently, a robust gene expression program involving motile cilia components and...
  • A novel WDR60 variant contributes to a late diagnosis of Jeune asphyxiating thoracic dystrophy in a Chinese patient: A case report
    We report a Chinese patient with JATD presenting a mild skeletal phenotype and with renal insufficiency as the initial symptom of the disease. A novel homozygous c.2789C>T (p.S930L) variant in the WDR60 gene was identified. Our report will help to improve awareness and diagnosability for this disease.

  • Bardet Biedl syndrome: a case report
    Bardet Biedl syndrome is an autosomal recessive ciliopathie. It is a pleiotropic disorder characterised by retinal dystrophy, renal dysfunction, polydactyly, obesity, cognitive deficit and hypogenitalism. Diagnosis is based on clinical features. Molecular genetic testing is available. There is no specific treatment, a multidisciplinary approach is required. We report the case of a 13-year-old female patient with obesity and hyperphagia, type 2 diabetes, hypothyroidism, polydactyly, cognitive...
  • Structures and functions of cilia during vertebrate embryo development
    Cilia are hair-like structures that project from the surface of cells. In vertebrates, most cells have an immotile primary cilium that mediates cell signaling, and some specialized cells assemble one or multiple cilia that are motile and beat synchronously to move fluids in one direction. Gene mutations that alter cilia structure or function cause a broad spectrum of disorders termed ciliopathies that impact virtually every system in the body. A wide range of birth defects associated with...
  • Dietary Aspects and Drug-Related Side Effects in Autosomal Dominant Polycystic Kidney Disease Progression
    Autosomal dominant polycystic kidney disease (ADPKD) is the most commonly inherited kidney disease. In the absence of targeted therapies, it invariably progresses to advanced chronic kidney disease. To date, the only approved treatment is tolvaptan, a vasopressin V2 receptor antagonist that has been demonstrated to reduce cyst growth and attenuate the decline in kidney function. However, it has various side effects, the most frequent of which is aquaresis, leading to a significant...
  • The Primary Cilium and Neuronal Migration
    The primary cilium (PC) is a microtubule-based tiny sensory organelle emanating from the centrosome and protruding from the surface of most eukaryotic cells, including neurons. The extremely severe phenotypes of ciliopathies have suggested their paramount importance for multiple developmental events, including brain formation. Neuronal migration is an essential step of neural development, with all neurons traveling from their site of birth to their site of integration. Neurons perform a unique...
  • Recurrent haematospermia: an unusual presentation of autosomal dominant polycystic kidney disease
    Haematospermia, even though alarming, is usually benign and self-limiting, especially in a sexually active male. Nevertheless recurrent, refractory or painful haematospermia is troublesome and warrants thorough evaluation. In this context, we describe a rare case of recurrent haematospermia whereby evaluation revealed haemorrhage in seminal vesicle cysts and consequently established the aetiology of autosomal dominant polycystic kidney disease.
  • Biochemically validated structural model of the 15-subunit intraflagellar transport complex IFT-B
    Cilia are ubiquitous eukaryotic organelles impotant for cellular motility, signaling, and sensory reception. Cilium formation requires intraflagellar transport of structural and signaling components and involves 22 different proteins organized into intraflagellar transport (IFT) complexes IFT-A and IFT-B that are transported by molecular motors. The IFT-B complex constitutes the backbone of polymeric IFT trains carrying cargo between the cilium and the cell body. Currently, high-resolution...
  • Modulation of P2X4 receptor activity by ivermectin and 5-BDBD has no effect on the development of ARPKD in PCK rats
    Autosomal recessive polycystic kidney disease (ARPKD) is an inherited pathology caused mainly by mutations of the polycystic kidney and hepatic disease 1 (PKHD1) gene, which usually leads to end-stage renal disease. Previous studies suggested that the P2X purinoreceptor 4 (P2X(4) R) may play an important role in the progression of ARPKD. To test this hypothesis, we assessed the chronic effects of ivermectin (P2X(4) R allosteric modulator) and 5-BDBD (P2X(4) R antagonist) on the development of...
  • Integrative modeling reveals the molecular architecture of the intraflagellar transport A (IFT-A) complex
    Intraflagellar transport (IFT) is a conserved process of cargo transport in cilia that is essential for development and homeostasis in organisms ranging from algae to vertebrates. In humans, variants in genes encoding subunits of the cargo-adapting IFT-A and IFT-B protein complexes are a common cause of genetic diseases known as ciliopathies. While recent progress has been made in determining the atomic structure of IFT-B, little is known of the structural biology of IFT-A. Here, we combined...
