Circulating tumor DNA (ctDNA), small pieces of DNA released from dying tumor cells into the bloodstream, can be easily and non-invasively identified and examined through a simple blood test. This ...

A new study has punctured a longstanding assumption about the source of the most common type of DNA mutation seen in the genome--one that contributes to many genetic diseases, including cancer. A ...

A new microfluidic chip simplifies detecting and quantifying DNA by analyzing electrical impedance signals that vary based on DNA flowing across a biosensor inside the chip. The proof-of-concept ...

While the genes involved can differ, this example illustrates how most cancers arise. Accumulated DNA mutations, acquired ...

What Is the MTHFR Gene Mutation? The MTHFR gene mutation is a variation in the MTHFR gene. This gene normally tells your body how to make the MTHFR protein. You need this protein to process folate, ...

A microfluidic device barely larger than a U.S. quarter and developed by a Rutgers University-led team can detect rare genetic mutations from a single drop of blood. A team led by Rutgers ...

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body's typically efficient DNA repair machinery and potentially affecting our health ...

A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...
