Direct-to-consumer genomic testing: systematic review of the literature on user perspectives.

European Journal of Human Genetics : EJHG

Abstract

Genetic tests have traditionally been offered by health professionals. However, genomic tests have been available direct to the consumer for the last decade, increasingly via the Internet. The aim of this systematic review was to ascertain the evidence concerning use of direct-to-consumer genomic testing from the consumer perspective. Primary research was identified using the search terms 'direct-to-consumer' and 'genomic or genetic' in six bibliographic databases and citation searching of findings. In all, 17 papers were reviewed: 3 qualitative and 14 quantitative. Findings indicate a low level of awareness of direct-to-consumer genomic testing and, because of the hypothetical nature of many studies, little evidence from users of such tests. Although potential users appear to be interested in information about their risks of developing common diseases, concerns were expressed about privacy of genetic risk information and the reliability of genomic tests. Consumers were anxious about the nature of the results. There appeared to be a preference to access genomic tests via a health professional, or to discuss the results and obtain advice from a health professional. Authors of only two papers recruited participants who had used d...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
