To Opt or Not to Opt for Preimplantation and/or Prenatal Genetic Testing?

Received: 05 June 2018;  Published: 23 July 2018;  doi: 10.21926/obm.genet.1803024


Both preimplantation genetic testing and prenatal testing are powerful tools to tackle the transmission of inherited disorders in families carrying the diseases from generation to generation. This article presents an overview of the current landscape of both methods and identifies the pros and cons [...]

Unusual Ways to Lose a Y Chromosome and Survive with Changed Autosomes: a Story of Mole Voles Ellobius (Mammalia, Rodentia)

Received: 16 May 2018;  Published: 22 July 2018;  doi: 10.21926/obm.genet.1803023


When does reproduction start? An old question of the chicken and the egg is even more complicated in relation to mole voles Ellobius. First, ‘chicken’ should be a female, and males are obviously involved in reproduction too because zygote is a result of sperm and oocyte fusion. But nobody knows how [...]

On Objectivity in Prenatal Genetic Care

Received: 16 April 2018;  Published: 12 June 2018;  doi: 10.21926/obm.genet.1802022


We address an ongoing controversy over what health-care providers tell prospective parents about Down Syndrome (DS). In the view of critics, including many parent, disability-rights, and anti-abortion activists, the messages that health-care professionals transmit to pregnant women and their partner [...]

User-Friendly Approach to Gain Isolation of Interphase Cells for Fluorescence in Situ Hybridization

Received: 16 March 2018;  Published: 17 May 2018;  doi: 10.21926/obm.genet.1802021


(1) Background: Fluorescence in situ hybridization (FISH) may be performed on metaphase- and/or interphase cells. Metaphase cells can exclusively be obtained and studied after time consuming cell culture. Therefore suited cells derive from peripheral blood, bone marrow or fibroblasts, the latter inc [...]

Non-Coding RNAs in Cutaneous Melanoma Development, Progression and Dissemination

Received: 13 March 2018;  Published: 15 May 2018;  doi: 10.21926/obm.genet.1802020


Melanoma is a highly aggressive skin cancer with high incidence worldwide. There are growing evidences that aberrantly expressed non-coding RNAs (ncRNAs) play a role in the development, progression and dissemination of melanoma tumor cells. Among the many types of ncRNAs, we will describe in this re [...]

German Guidelines for Molecular Genetic Diagnostic Testing Using High-throughput Technology, Such As Next-Generation Sequencing

Received: 24 September 2017;  Published: 28 April 2018;  doi: 10.21926/obm.genet.1802019


We present, on behalf of the German Society of Human Genetics, guidelines for molecular genetic diagnostics with high throughput technology, for example using Next-Generation Sequencing. This work was put together by a group of experts and included public commenting of the members of the German Soci [...]

Moving Towards Routine Non-Invasive Prenatal Testing (NIPT): Challenges Related to Women’s Autonomy

Received: 10 February 2018;  Published: 19 April 2018;  doi: 10.21926/obm.genet.1802018


Women’s reproductive autonomy, and its translation into informed free choice regarding prenatal testing, is a dominant concept in the bioethical discourse concerning prenatal testing. This discourse is based on the premise that access to information regarding the pregnancy promotes autonomous decisi [...]

Identification and Prioritization of Causal Variants of Human Genetic Disorders from Exome or Whole Genome Sequencing Data

Received: 24 October 2017;  Published: 16 April 2018;  doi: 10.21926/obm.genet.1802017


With genome sequencing entering the clinics as diagnostic tool to study genetic disorders, there is an increasing need for bioinformatics solutions that enable precise causal variant identification in a timely manner. Background: Workflows for the identification of candidate disease-causing variants [...]

Current Understanding of DNA Methylation and Age-related Disease

Received: 12 February 2018;  Published: 11 April 2018;  doi: 10.21926/obm.genet.1802016


DNA methylation involves the covalent transfer of a methyl group to the C-5 position of the cytosine ring on a DNA strand which can affect gene transcription. DNA methylation is both heritable and modifiable. In recent years, epigenome-wide association studies using high-throughput technologies have [...]

Application of Clinical Next Generation Sequencing in Intensive Care Facilitates Rapid Diagnosis of Neonates with Rare Genetic Disorders

Received: 31 August 2017;  Published: 06 March 2018;  doi: 10.21926/obm.genet.1801015


Background: Neonatal muscular hypotonia is a common clinical feature on neonatal intensive care units with a broad spectrum of etiologies. Besides more common and obvious underlying conditions like prematurity or Down syndrome many rare disorders with often poor prognosis need to be considered. Cong [...]
