    Function of Ltbp-4L and fibulin-4 in survival and elastogenesis in mice.
    Dis Model Mech 2016 Nov 1;9(11):1367-1374. Epub 2016 Sep 1.
    Center for Experimental Medicine, Medical Faculty, University of Cologne, 50931 Cologne, Germany
    LTBP-4L and LTBP-4S are two isoforms of the extracellular matrix protein latent-transforming growth factor beta-binding protein 4 (LTBP-4). The mutational inactivation of both isoforms causes autosomal recessive cutis laxa type 1C (ARCL1C) in humans and an ARCL1C-like phenotype in Ltbp4(-/-) mice, both characterized by high postnatal mortality and severely affected elastogenesis. However, genetic data in mice suggest isoform-specific functions for Ltbp-4 because Ltbp4S(-/-) mice, solely expressing Ltbp-4L, survive to adulthood. Read More

    Vesicoureteral reflux and the extracellular matrix connection.
    Pediatr Nephrol 2016 May 2. Epub 2016 May 2.
    Department of Human Genetics, McGill University, Montreal, QC, Canada.
    Primary vesicoureteral reflux (VUR) is a common pediatric condition due to a developmental defect in the ureterovesical junction. The prevalence of VUR among individuals with connective tissue disorders, as well as the importance of the ureter and bladder wall musculature for the anti-reflux mechanism, suggest that defects in the extracellular matrix (ECM) within the ureterovesical junction may result in VUR. This review will discuss the function of the smooth muscle and its supporting ECM microenvironment with respect to VUR, and explore the association of VUR with mutations in ECM-related genes.

    We report on the case of a child who presented with recurrent, multiple, and voluminous bladder diverticula. Bladder diverticula are defined as a herniation of the mucosa through the bladder muscle or the detrusor. Causes are numerous and diverticula can be classified into primary congenital diverticula (para-ureteral - or Hutch diverticula - and posterolateral diverticula); secondary diverticula (resulting from chronic mechanical obstruction or from neurological disease; and diverticula secondary to connective tissue or muscle fragility.

    Background: Finnish type of hereditary gelsolin amyloidosis (FGA) is one of the most common diseases of Finnish disease heritage. Existing FGA knowledge is based only on smaller patient series, so our aim was to elucidate the natural course of the disease in a comprehensive sample of patients and to build up a national FGA patient registry.

    Methods: An inquiry about the known and suspected signs of FGA, sent to the members of Finnish Amyloidosis Association, telephone contacts, and hospital records were utilized to create the registry. Read More

    Progeroid disorders overlapping with De Barsy syndrome (DBS) are collectively denoted as autosomal-recessive cutis laxa type 3 (ARCL3). They are caused by biallelic mutations in PYCR1 or ALDH18A1, encoding pyrroline-5-carboxylate reductase 1 and pyrroline-5-carboxylate synthase (P5CS), respectively, which both operate in the mitochondrial proline cycle. We report here on eight unrelated individuals born to non-consanguineous families clinically diagnosed with DBS or wrinkly skin syndrome. Read More
