Genetic testing for diagnosing rare diseases: are we there yet?

With the advances made in next-generation sequencing technologies personalized medicine, caring for patients based on a genetic understanding of their disease, may soon become a reality. What does this change in the genetic testing landscape mean for rare diseases? Are we at a point where we can use next-generation sequencing-based genetic testing to accurately diagnose […]

Healthy aging using the power of DNA

Researchers publish a reference DNA database for healthy older Australians in an attempt to establish a baseline for healthy aging. The aging population problem Owing to the amazing advances made in science and medicine, the elderly population in the world is the highest it has even been in human history. Life expectancy has increased over […]

CRISPR goes mainstream: gene therapy to cure hereditary blindness in patients

In a first of its kind trial, scientists deliver CRISPR-Cas9 gene therapy directly into the eye of a patient with hereditary blindness. Gene editing with CRISPR Gene editing involves making specific changes to the DNA sequence. This is usually achieved by creating a break at a specific region of DNA and modifying the DNA sequence […]

Would a DNA vaccine be able to stand ground against COVID-19?

With so many countries under lockdown, researchers from around the world are racing against time to develop a vaccine for COVID-19. Keeping with our theme of DNA, we explore the topic of DNA vaccines and their potential for battling the COVID-19 pandemic. The purpose of a vaccine Immunity is the key to protecting the body […]

Alzheimer’s disease risk can be moderated, a new study finds

Researchers identify 21 modifiable risk factors for reducing the risk of developing Alzheimer’s disease. The APOE gene is one of the most-significant genetic risk factors associated with late-onset Alzheimer’s disease. But many people, even those with a family history of Alzheimer’s, have often hesitated before taking a DNA test to assess their risk, until now. A recent […]

ACE2: Genetic clues to COVID-19 infections and treatment

Scientists identify a possible link between genetic variations in the ACE-2 receptor used by coronaviruses to enter cells and susceptibility to COVID-19 infections. Could your genetics protect you from an illness, and would genetic testing be helpful during treatment?   The beginning of a viral infection Viruses are parasites. They have to hijack the cellular machinery […]

Study finds a link between the severity of COVID-19 infections and blood type

Researchers link genetic changes in the region of DNA that define blood type with susceptibility to COVID-19 infections. Blood type O offers a protective effect, while type A is linked to an increased risk of being infected. More than 8 million people worldwide have been infected with COVID-19. Italy and Spain were hit hard at […]
