Kropatsch et al. Canine Genetics and Epidemiology (2016) 3:7 DOI 10.1186/s40575-016-0037-x RESEARCH Open Access A large deletion in RPGR causes XLPRA in Weimaraner dogs Regina Kropatsch1*, Denis A. Akkad1, Matthias Frank2, Carsten Rosenhagen3, Janine Altmüller4,5, Peter Nürnberg4,6,7, Jörg T. Epplen1,8 and Gabriele Dekomien1 Abstract Background: Progressive retinal atrophy (PRA) belongs to a group of inherited retinal disorders associated with gradual vision impairment due to degeneration of retinal photoreceptors in various dog breeds. PRA is highly heterogeneous, with autosomal dominant, recessive or X-linked modes of inheritance. In this study we used exome sequencing to investigate the molecular genetic basis of a new type of PRA, which occurred spontaneously in a litter of German short-hair Weimaraner dogs. Results: Whole exome sequencing in two PRA-affected Weimaraner dogs identified a large deletion comprising the first four exons of the X-linked retinitis pigmentosa GTPase regulator (RPGR) gene known to be involved in human retinitis pigmentosa and canine PRA. Screening of 16 individuals in the corresponding pedigree of short-hair Weimaraners by qPCR, verified the deletion in hemizygous or heterozygous state in one male and six female dogs, respectively. The mutation was absent in 88 additional unrelated Weimaraners. The deletion was not detectable in the parents of one older female which transmitted the mutation to her offspring, indicating that the RPGR deletion represents a de novo mutation concerning only recent generations of the Weimaraner breed in Germany. Conclusion: Our results demonstrate the value of an existing DNA biobank combined with exome sequencing to identify the underlying genetic cause of a spontaneously occurring inherited disease. -
Analysis of Trans Esnps Infers Regulatory Network Architecture
Analysis of trans eSNPs infers regulatory network architecture Anat Kreimer Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2014 © 2014 Anat Kreimer All rights reserved ABSTRACT Analysis of trans eSNPs infers regulatory network architecture Anat Kreimer eSNPs are genetic variants associated with transcript expression levels. The characteristics of such variants highlight their importance and present a unique opportunity for studying gene regulation. eSNPs affect most genes and their cell type specificity can shed light on different processes that are activated in each cell. They can identify functional variants by connecting SNPs that are implicated in disease to a molecular mechanism. Examining eSNPs that are associated with distal genes can provide insights regarding the inference of regulatory networks but also presents challenges due to the high statistical burden of multiple testing. Such association studies allow: simultaneous investigation of many gene expression phenotypes without assuming any prior knowledge and identification of unknown regulators of gene expression while uncovering directionality. This thesis will focus on such distal eSNPs to map regulatory interactions between different loci and expose the architecture of the regulatory network defined by such interactions. We develop novel computational approaches and apply them to genetics-genomics data in human. We go beyond pairwise interactions to define network motifs, including regulatory modules and bi-fan structures, showing them to be prevalent in real data and exposing distinct attributes of such arrangements. We project eSNP associations onto a protein-protein interaction network to expose topological properties of eSNPs and their targets and highlight different modes of distal regulation. -

INTRODUCTION Published in May 2007, U.S. application no. 20070122826 (Venter patent) describes a minimally operative genome of the bacterium Mycoplasma genitalium consisting of 381 genes, which the inventors believe to be essential for the survival of the bacterium in an environment containing all the necessary nutrients and free from stress.1 However, the team of inventors from the J. Craig Venter Institute is trying to accomplish something more than just the usual patenting of genes; they intend to create and patent the world’s first artificial organism. The team has already cleared two of the three major hurdles on its way to constructing this first synthetic organism. In January 2008, they announced completion of the second step, the laboratory synthesis of the entire 582,970 base pairs of the genome described in the patent above.2 What remains is the third and final step of inserting this human-made genome into a bacterial cell chassis and “booting up” the organism.3 Craig Venter and Hamilton Smith, lead researchers on the team have been discussing the creation of synthetic life since 1995, when their team published the first complete genome sequence of a living * © 2008 Michael Saunders.

Mouse Germ Line Mutations Due to Retrotransposon Insertions Liane Gagnier1, Victoria P
Gagnier et al. Mobile DNA (2019) 10:15 https://doi.org/10.1186/s13100-019-0157-4 REVIEW Open Access Mouse germ line mutations due to retrotransposon insertions Liane Gagnier1, Victoria P. Belancio2 and Dixie L. Mager1* Abstract Transposable element (TE) insertions are responsible for a significant fraction of spontaneous germ line mutations reported in inbred mouse strains. This major contribution of TEs to the mutational landscape in mouse contrasts with the situation in human, where their relative contribution as germ line insertional mutagens is much lower. In this focussed review, we provide comprehensive lists of TE-induced mouse mutations, discuss the different TE types involved in these insertional mutations and elaborate on particularly interesting cases. We also discuss differences and similarities between the mutational role of TEs in mice and humans.

BCL-2 Family Proteins: Changing Partners in the Dance Towards Death
Cell Death and Differentiation (2018) 25, 65–80 OPEN Official journal of the Cell Death Differentiation Association www.nature.com/cdd Review BCL-2 family proteins: changing partners in the dance towards death Justin Kale1, Elizabeth J Osterlund1,2 and David W Andrews*,1,2,3 The BCL-2 family of proteins controls cell death primarily by direct binding interactions that regulate mitochondrial outer membrane permeabilization (MOMP) leading to the irreversible release of intermembrane space proteins, subsequent caspase activation and apoptosis. The affinities and relative abundance of the BCL-2 family proteins dictate the predominate interactions between anti-apoptotic and pro-apoptotic BCL-2 family proteins that regulate MOMP. We highlight the core mechanisms of BCL-2 family regulation of MOMP with an emphasis on how the interactions between the BCL-2 family proteins govern cell fate. We address the critical importance of both the concentration and affinities of BCL-2 family proteins and show how differences in either can greatly change the outcome. Further, we explain the importance of using full-length BCL-2 family proteins (versus truncated versions or peptides) to parse out the core mechanisms of MOMP regulation by the BCL-2 family. Finally, we discuss how post- translational modifications and differing intracellular localizations alter the mechanisms of apoptosis regulation by BCL-2 family proteins. Successful therapeutic intervention of MOMP regulation in human disease requires an understanding of the factors that mediate the major binding interactions between BCL-2 family proteins in cells. Cell Death and Differentiation (2018) 25, 65–80; doi:10.1038/cdd.2017.186; published online 17 November 2017 The membrane plays an active role in most BCL-2 family interactions by changing the affinities and local relative abundance of these proteins. -

Are there alternatice treatments? Description of engineering technique No institution visited Discussion What progress was made with the application of the chosen technique? What future research steps? Ethical aspects Summary References PREFACE What is my motivation to work on the chosen topic? There are many reasons. One of them is that it’s a very interesting topic. It is fascinating, how you can increase or decrease the functionality of organisms. What is especially interesting? The intricacy. And that you can use the method not only for mice but for every organism. For example in the Green genetic engineering (to make plants more resistant) or for pharmaceuticals like human insulin. Some genes are responsible for the aging process. So if we can find those genes and deactivate them we would life longer. First successful experiments with animals where already made. What I also like about this topic is the big ethic question behind it. I mean in the end we use animals, often mice because of their similarity to our genes, to benefit of them. We intentional make them ill and lock them into small cages. But on the other hands medicaments can be tested or invented which can save many human lifes. -
Genetics and Genomics of Human Population Structure 20
Genetics and Genomics of Human Population Structure 20 Sohini Ramachandran , Hua Tang , Ryan N. Gutenkunst , and Carlos D. Bustamante Abstract Recent developments in sequencing technology have created a fl ood of new data on human genetic variation, and this data has yielded new insights into human popu- lation structure. Here we review what both early and more recent studies have taught us about human population structure and history. Early studies showed that most human genetic variation occurs within populations rather than between them, and that genetically related populations often cluster geographically. Recent studies based on much larger data sets have recapitulated these observations, but have also demonstrated that high-density genotyping allows individuals to be reliably assigned to their population of origin. In fact, for admixed individuals, even the ancestry of particular genomic regions can often be reli- ably inferred. Recent studies have also offered detailed information about the composition of specifi c populations from around the world, revealing how history has shaped their genetic makeup. We also briefl y review quantitative models of human genetic history, including the role natural selection has played in shaping human genetic variation.

McCarthy17,30,31,32* Published online: 8 January 2020 A primary goal of human genetics is to identify DNA sequence variants that infuence biomedical traits, particularly those related to the onset and progression of human disease. Over the past 25 years, progress in realizing this objective has been transformed by advances in technology, foundational genomic resources and analytical tools, and by access to vast amounts of genotype and phenotype data. Genetic discoveries have substantially improved our understanding of the mechanisms responsible for many rare and common diseases and driven development of novel preventative and therapeutic strategies. Medical innovation will increasingly focus on delivering care tailored to individual patterns of genetic predisposition. medicine, which was previously restricted to a few specific clinical Anniversary indications, is poised to go mainstream. collection: This Review charts recent milestones in the history of human disease go.nature.com/ genetics and provides an opportunity to reflect on lessons learned by nature150 the human genetics community.

April 1988 NTIS order #PB88-212402 Recommended Citation: U.S. Congress, Office of Technology Assessment, Mapping Our Genes-The Genmne Projects.’ How Big, How Fast? OTA-BA-373 (Washington, DC: U.S. Government Printing Office, April 1988). Library of Congress Catalog Card Number 87-619898 For sale by the Superintendent of Documents U.S. Government Printing Office, Washington, DC 20402-9325 (order form can be found in the back of this report) Foreword For the past 2 years, scientific and technical journals in biology and medicine have extensively covered a debate about whether and how to determine the function and order of human genes on human chromosomes and when to determine the sequence of molecular building blocks that comprise DNA in those chromosomes. In 1987, these issues rose to become part of the public agenda. The debate involves science, technol- ogy, and politics. Congress is responsible for ‘(writing the rules” of what various Federal agencies do and for funding their work. This report surveys the points made so far in the debate, focusing on those that most directly influence the policy options facing the U.S. Congress, The House Committee on Energy and Commerce requested that OTA undertake the project. The House Committee on Science, Space, and Technology, the Senate Com- mittee on Labor and Human Resources, and the Senate Committee on Energy and Natu- ral Resources also asked OTA to address specific points of concern to them. Congres- sional interest focused on several issues: ● how to assess the rationales for conducting human genome projects, ● how to fund human genome projects (at what level and through which mech- anisms), ● how to coordinate the scientific and technical programs of the several Federal agencies and private interests already supporting various genome projects, and ● how to strike a balance regarding the impact of genome projects on international scientific cooperation and international economic competition in biotechnology.
