Genetic testing provides patients with a diagnosis for their illness, helps patients and family members to understand risks of developing new diseases, and can be used to support clinical trial advancement. What are the benefits and limitations to using genetic testing? It is important to consider the type of testing performed (e.g.,
Genome sequencing, where scientists use laboratory methods to determine a specific organism’s genetic makeup, is becoming a common practice in insect research.
In 2016, scientists behind a study called the Resilience Project analysed genetic data from 589,000+ people and found 13 adults who carried genetic variants that should have resulted in serious – even deadly – childhood disease, but who were apparently healthy. Giving participants something in return. with their priorities.
A Swedish scientist won the 2022 Nobel Prize in medicine or physiology on Monday for his groundbreaking research into the evolutionary history of humankind. Pääbo unlocked scientists’ understanding of how genes from these extinct relatives have been passed down to present-day humans.

Tissue collection at NOAA Fisheries lab helps reveal genetic distinction Credit: Mansur/WCR Bangladesh New genetic analysis and years of painstaking research has revealed that one of the world’s most endangered marine mammals is actually two species rather than one, as scientists had long assumed.
Credit: UPMC PITTSBURGH, May 7, 2021 – In a paper published today in Nature Communications, an international group of collaborators led by researchers at UPMC Children’s Hospital of Pittsburgh have identified a genetic cause of a rare neurological disorder marked by developmental delay and loss of coordination, or ataxia.
Ben Hargreaves finds that the vast amount of genetic data that exists today could help provide a faster, more targeted way of developing new drug candidates. The logical extension to this kind of approach is treating individual patients, with their individual genetic makeup.
The Cambridge biotech company announced Wednesday that it will partner with Life Edit Therapeutics to develop potentially permanent treatments for rare genetic diseases and other conditions. Life Edit is the North Carolina subsidiary of ElevateBio, a cell and gene therapy manufacturing firm in Waltham.
A web-based digital tool called Helix could help clinicians identify patients with prostate cancer who would benefit from genetic testing and counselling, according to researchers in the US. “Our digital solution, Helix, demonstrated promising results for clinical use,” write the researchers in the paper.
BEIJING — Hong Kong on Tuesday revoked a visa it granted to a Chinese scientist who set off an ethical debate five years ago with claims that he made the world’s first genetically edited babies, pulling it hours after he announced his research plans in the financial hub.
Jude Children’s Research Hospital scientists have developed a highly efficient method to address a major challenge in biology–identifying the genetic ‘switches’ that regulate gene expression. Jude Children’s Research Hospital St. Credit: St.
