Genetic Variants of Targetable Cancer-related Genes in Vestibular Schwannomas

Received: 02 May 2020;  Published: 28 June 2020;  doi: 10.21926/obm.genet.2002112


Background: Vestibular schwannoma is an intracranial tumor which can lead to devastating neurological deficit and is prone to recurrence after surgery. Patients with inherited neurofibromatosis type 2 (NF2) syndrome are particularly susceptible to bilateral and aggressive schwannomas. However, the genome of vestibular schwannomas is not well known. There is an imminent need of developing effective chemotherapeutic agents either as a primary treatment modality or as adjuvant therapy for these pat [...]

Genetic Explanations for Fertility Disorders

Received: 02 May 2020;  Published: 23 June 2020;  doi: 10.21926/obm.genet.2002111


This article reviews the genetic testing of infertility disorders. Genetic abnormalities can lead to disturbances of sexual development and hamper reproduction by influencing gamete production and maturation, fertilization, and embryonic development. Until now, the vast majority of detectable genetic abnormalities causing infertility were chromosomal abnormalities in both males and females. However, the number of monogenetic disorders, which play a role in disturbing fertility, such as single ge [...]

Splicing HAC1/XBP1 mRNAs in Cytoplasm: The Non-Conventional mRNA Splicing Reaction in the Unfolded Protein Response

Received: 23 March 2020;  Published: 22 May 2020;  doi: 10.21926/obm.genet.2002110


The majority of the secretory and transmembrane proteins are folded in the endoplasmic reticulum (ER). When unfolded proteins accumulate in the ER, a collective of signalling pathways, termed the unfolded protein response (UPR), are activated to restore the ER protein folding homeostasis. The most evolutionarily conserved branch of UPR is mediated by the kinase/endoribonuclease Ire1. Ire1 mediates a cytosolic non-conventional mRNA splicing reaction of HAC1 mRNA in yeast and [...]

HER2 FISH for Breast Cancer: Advances in Quantitative Image Analysis and Automation

Received: 02 March 2020;  Published: 13 May 2020;  doi: 10.21926/obm.genet.2002109


Quantitative image analysis of the status of human epidermal growth factor receptor 2 (HER2) by both immunohistochemistry staining and fluorescent in situ hybridization (FISH) is important for the treatment of breast cancer. Guidelines of the American Society for Clinical Oncology and College of American Pathologists, for HER2 FISH, have evolved over time to improve test accuracy, and efforts have been made to better address the problems with the interpretation that are encountered with borderli [...]

Professionals’ Views on Offering Pre-Natal Testing for Adult Onset Cancer Susceptibility. Reconciling Personal and Professional Ethical Conflicts, Coping Strategies and Need for Policy Transparency

Received: 30 December 2019;  Published: 26 April 2020;  doi: 10.21926/obm.genet.2002108


This paper explores views of healthcare professionals (HCPs) in genetics and foetal medicine settings on offering pre-natal diagnosis (PND) for adult onset cancer susceptibility (AOCS) genes. Study participants came from different disciplinary backgrounds and all had considered implications of offering PND for AOCS, directly or indirectly, from professional and personal perspectives. Foetal medicine and genetics teams are accustomed to offering PND with the possibility of terminating an affected [...]

MSIGNET: A Bayesian Approach for Disease-associated Gene Network Identification

Received: 19 October 2019;  Published: 07 April 2020;  doi: 10.21926/obm.genet.2002107


The analysis of gene networks and signalling pathways plays a key role in understanding gene functions, i.e., their effects on the development of a particular disease. Yet, for many heterogeneous diseases, the number of known disease-associated genes is limited. Identifying disease-associated genes is still an open challenge. To understand the functions of genes associated with a disease, we develop a Metropolis-Hastings sampling based SIGnificant NETwork (MS [...]
