Cover story: Pneumocystis have coevolved with their mammalian hosts for millions of years. As a result, there are clear evidences of positive selection in the genes coding for major surface glycoproteins (MSG) in Pneumocystis. Here we question whether there are evidences of positive selection in the genes coding for the biosynthesis of GPI which is the molecule used by Pneumocystis to target MSG to the cell membrane.

Thalassemia Intermedia Caused by a Combination of a Globin Gene Triplication with Heterozygosity for β0 Thalassemia: A Case Report

Received: 19 May 2019;  Published: 17 September 2019;  doi: 10.21926/obm.genet.1903095


Thalassemia syndromes are a group of hemoglobinopathies characterized by gene defects that disrupt hemoglobin synthesis. Thalassemia intermediate is referred to a group of disorders with a less severe form of the disease when compared with thalassemia major. We present the case of a 60 year old w [...]

Newborn Screening for Genetic Diseases: An Overview of Current and Future Applications

Received: 01 July 2019;  Published: 06 September 2019;  doi: 10.21926/obm.genet.1903093


Newborn screening (NBS) for inborn errors of metabolism (IEM) was introduced more than 50 years ago with the testing of phenylketonuria (PKU) using blood spots deposited on a filter paper after heel prick. NBS aims to identify early after birth inherited disorders for which clinical management and p [...]

Upregulation of COX-2 in MCF7 Breast Cancer Cells When Exposed to Shear Stress

Received: 17 June 2019;  Published: 06 September 2019;  doi: 10.21926/obm.genet.1903092


Background: Invasive breast cancer affects 1 in 8 women in the United States and causes one of the highest cancer mortality rates for women. Cyclooxygenase-2 (COX-2), a central enzyme in prostaglandin biosynthesis, is implicated in breast cancer initiation, progression, invasion, metastasis, and has [...]

Deletion of Subtelomeric Regions in the Linear Chromosome of Variants Isolated from Streptomyces avermitilis NBRC 14893T

Received: 19 April 2019;  Published: 23 August 2019;  doi: 10.21926/obm.genet.1903091


Background: Streptomyces avermitilis is an actinomytcete producing avermectins and the complete genome sequence of S. avermitilis K139 was determined in 2003. In our previous study, we have revealed that S. avermitilis NBRC 14893T harbors two extra secondary metabolite-biosynthetic gene clusters (sm [...]

Diagnosis and Treatment of Mitochondrial Abnormalities in Reproductive Medicine

Received: 08 April 2019;  Published: 14 August 2019;  doi: 10.21926/obm.genet.1903089


Mitochondrial diseases represent the most common inborn errors of metabolism. The overwhelming majority of mitochondrial diseases (about 85 %) are caused by mutations of nuclear genes of oxidative phosphorylation. The remaining 15 % are caused by mtDNA mutations. The familial mtDNA mutations are exc [...]

Next-Generation Sequencing-Based Testing in Diagnostic Oncohematology: Untangling the Knots

Received: 01 April 2019;  Published: 09 August 2019;  doi: 10.21926/obm.genet.1903088


With the advent of next generation sequencing (NGS), genomic profiling of tumors has gradually been introduced into the clinical setting and become a standard in cancer care. NGS allows easier, faster and cheaper sequencing and commercially available panels enable the detection of single or global [...]

Family History, Genetic, and Other Cause-Related Beliefs among Breast Cancer Survivors

Received: 27 February 2019;  Published: 26 July 2019;  doi: 10.21926/obm.genet.1903087


Patients’ lay theories about the cause of their cancer may influence patient behavior and adjustment, they have also been found to differ substantially from scientific evidence of cancer risk factors. This report describes beliefs about genetic causes of breast cancer, among 522 recently diagnosed b [...]

The Evolution of DNA Typing in Agri-Food Chain

Received: 11 June 2019;  Published: 23 July 2019;  doi: 10.21926/obm.genet.1903086


Background: DNA typing has revolutionised not only diagnostics and forensics but also how we can analyse food. A number of techniques have been successfully applied for DNA analysis of plant-derived food however, unlike forensics, no method has become universally employed. Methods: A keyword-based s [...]

Constitutional Partial Proximal Trisomy 14q11.2 to 14q21: Two New Moroccan Cases and Review of the Literature

Received: 25 July 2018;  Published: 22 July 2019;  doi: 10.21926/obm.genet.1903085


Small supernumerary marker chromosomes (sSMCs), a major problem in clinical cytogenetics, are too small to be characterized for their chromosomal origin by cytogenetic banding techniques. Most sSMCs have not yet been correlated with a specific clinical syndrome, and genotype-phenotype correlation in [...]

Preimplantation Genetic Testing for HLA-matching: An Overview of Clinical Application and Utility

Received: 03 June 2019;  Published: 22 July 2019;  doi: 10.21926/obm.genet.1903084


Preimplantation Genetic Testing for HLA-matching (PGT-HLA) has been one of the most controversial PGT applications, first reported in 2001. The procedure aims to identify an embryo that is not only healthy but also HLA-matched with a sibling in the family in need of haematopoietic stem cell transpla [...]

Genes Coding for GPI Biosynthesis in Pneumocystis Experienced Relaxed Selection: A Follow-up Study

Received: 05 May 2019;  Published: 11 July 2019;  doi: 10.21926/obm.genet.1903083


Background: Phylogenetic analyses shows that Pneumocystis species have coevolved with their mammalian hosts for millions of years. As a result, infection by Pneumocystis is species specific (i.e. a given Pneumocystis species can infect only a single species of host). This specificity suggests the ex [...]
