The coded protein can play a role in secretory processes and also has interacXons with proteins involved in mitosis. Muta3ons and pathologies: Geroderma osteodysplasXc, also called "Walt Disney nanism", is a rare autosomal recessive disorder affecXng connecXve Xssue; it is characterized by a loose and wrinkled skin and a prematurely aged appearance. Significant bone changes are present, involving advanced osteoporosis that can lead to mulXple fractures, hypoplasia (reduced development) of the jaw and a variable degree of growth deficit. Bones can also present mulXple lines similar to tree growth rings. (a) Lax skin on the abdomen in younger sibling demonstrated by pinching the skin.

However, the limits are not as great as with many similar disorders of cuXs laxa syndrome. in fact only generalized osteoporosis requires constant monitoring and therapy; bisphosphonates were effecXve in cases with serious presence of osteopenia. Naturally, frequently occurring fractures must be treated at any Xme; in the course of life, however, fractures gradually decrease and the bone metabolism normalizes. Eye disorders also need constant monitoring, because corneal clouding and even glaucoma can occur. However, eye symptoms are not always present. The affected person has progeroid cha- racterisXcs. CURIOSITY: The disease is also called Walt Disney's dwarfism because those who are af- fected have some similariXes with the Walt Disney dwarfs.

  • Synergistic Genetic Interactions Between Pkhd1 and Pkd1 Result in an ARPKD-Like Phenotype in Murine Models
    BASIC RESEARCH www.jasn.org Synergistic Genetic Interactions between Pkhd1 and Pkd1 Result in an ARPKD-Like Phenotype in Murine Models Rory J. Olson,1 Katharina Hopp ,2 Harrison Wells,3 Jessica M. Smith,3 Jessica Furtado,1,4 Megan M. Constans,3 Diana L. Escobar,3 Aron M. Geurts,5 Vicente E. Torres,3 and Peter C. Harris 1,3 Due to the number of contributing authors, the affiliations are listed at the end of this article. ABSTRACT Background Autosomal recessive polycystic kidney disease (ARPKD) and autosomal dominant polycystic kidney disease (ADPKD) are genetically distinct, with ADPKD usually caused by the genes PKD1 or PKD2 (encoding polycystin-1 and polycystin-2, respectively) and ARPKD caused by PKHD1 (encoding fibrocys- tin/polyductin [FPC]). Primary cilia have been considered central to PKD pathogenesis due to protein localization and common cystic phenotypes in syndromic ciliopathies, but their relevance is questioned in the simple PKDs. ARPKD’s mild phenotype in murine models versus in humans has hampered investi- gating its pathogenesis. Methods To study the interaction between Pkhd1 and Pkd1, including dosage effects on the phenotype, we generated digenic mouse and rat models and characterized and compared digenic, monogenic, and wild-type phenotypes. Results The genetic interaction was synergistic in both species, with digenic animals exhibiting pheno- types of rapidly progressive PKD and early lethality resembling classic ARPKD. Genetic interaction be- tween Pkhd1 and Pkd1 depended on dosage in the digenic murine models, with no significant enhancement of the monogenic phenotype until a threshold of reduced expression at the second locus was breached.

  • Dramatic Nucleolar Dispersion in the Salivary Gland of Schwenkfeldina Sp
    www.nature.com/scientificreports OPEN Dramatic nucleolar dispersion in the salivary gland of Schwenkfeldina sp. (Diptera: Sciaridae) José Mariano Amabis & Eduardo Gorab * Micronucleoli are among the structures composing the peculiar scenario of the nucleolus in salivary gland nuclei of dipterans representative of Sciaridae. Micronucleolar bodies contain ribosomal DNA and RNA, are transcriptionally active and may appear free in the nucleoplasm or associated with specifc chromosome regions in salivary gland nuclei. This report deals with an extreme case of nucleolar fragmentation/dispersion detected in the salivary gland of Schwenkfeldina sp. Such a phenomenon in this species was found to be restricted to cell types undergoing polyteny and seems to be diferentially controlled according to the cell type. Furthermore, transcriptional activity was detected in virtually all the micronucleolar bodies generated in the salivary gland. The relative proportion of the rDNA in polytene and diploid tissues showed that rDNA under-replication did not occur in polytene nuclei suggesting that the nucleolar and concomitant rDNA dispersion in Schwenkfeldina sp. may refect a previously hypothesised process in order to counterbalance the rDNA loss due to the under-replication. The chromosomal distribution of epigenetic markers for the heterochromatin agreed with early cytological observations in this species suggesting that heterochromatin is spread throughout the chromosome length of Schwenkfeldina sp. A comparison made with results from another sciarid species argues for a role played by the heterochromatin in the establishment of the rDNA topology in polytene nuclei of Sciaridae. Transcriptional activity of ribosomal RNA (rRNA) genes in specifc chromosome regions is the primary event for the local assembly of the nucleolus, the starting site of ribosome biogenesis.

  • Functional Analysis of Structural Variation in the 2D and 3D Human Genome
    FUNCTIONAL ANALYSIS OF STRUCTURAL VARIATION IN THE 2D AND 3D HUMAN GENOME by Conor Mitchell Liam Nodzak A dissertation submitted to the faculty of The University of North Carolina at Charlotte in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Bioinformatics and Computational Biology Charlotte 2019 Approved by: Dr. Xinghua Mindy Shi Dr. Rebekah Rogers Dr. Jun-tao Guo Dr. Adam Reitzel ii c 2019 Conor Mitchell Liam Nodzak ALL RIGHTS RESERVED iii ABSTRACT CONOR MITCHELL LIAM NODZAK. Functional analysis of structural variation in the 2D and 3D human genome. (Under the direction of DR. XINGHUA MINDY SHI) The human genome consists of over 3 billion nucleotides that have an average distance of 3.4 Angstroms between each base, which equates to over two meters of DNA contained within the 125 µm3 volume diploid cell nuclei. The dense compaction of chromatin by the supercoiling of DNA forms distinct architectural modules called topologically associated domains (TADs), which keep protein-coding genes, noncoding RNAs and epigenetic regulatory elements in close nuclear space. It has recently been shown that these conserved chromatin structures may contribute to tissue-specific gene expression through the encapsulation of genes and cis-regulatory elements, and mutations that affect TADs can lead to developmental disorders and some forms of cancer. At the population-level, genomic structural variation contributes more to cumulative genetic difference than any other class of mutation, yet much remains to be studied as to how structural variation affects TADs. Here, we study the func- tional effects of structural variants (SVs) through the analysis of chromatin topology and gene activity for three trio families sampled from genetically diverse popula- tions from the Human Genome Structural Variation Consortium.

  • Mouse Gorab Conditional Knockout Project (CRISPR/Cas9)
    https://www.alphaknockout.com Mouse Gorab Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Gorab conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Gorab gene (NCBI Reference Sequence: NM_178883 ; Ensembl: ENSMUSG00000040124 ) is located on Mouse chromosome 1. 5 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 5 (Transcript: ENSMUST00000045138). Exon 2 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Gorab gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-30J21 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Mice homozygous for a null gene trap allele exhibit hunched posture, craniofacial abnormalities, neonatal lethality, respiratory distress, skin edema, decreased hair follicles, fewer dermal condensates and papillae, and impaired formation of primary cilia on dermal condensate cells. Exon 2 starts from about 5.62% of the coding region. The knockout of Exon 2 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 6353 bp, and the size of intron 2 for 3'-loxP site insertion: 2119 bp. The size of effective cKO region: ~858 bp. The cKO region does not have any other known gene.

Congenital cardiac defects represent the most common group of birth defects, affecting an estimated six per 1000 births. Genetic characterization of patients and families with cardiac defects has identified a number of genes required for heart development. Yet, despite the rapid pace of these advances, mutations affecting known genes still account for only a small fraction of congenital heart defects suggesting that many more genes and developmental mechanisms remain to be identified. Design. In this study, we reviewed 1694 described cases of patients with cardiac defects who were determined to have a significant chromosomal imbalance (a deletion or duplication). The cases were collected from publicly available databases (DECIPHER, ISCA, and CHDWiki) and from recent publications.
