Researchers at Cardiff University have uncovered how a particularly severe form of DNA damage arises—shedding new light on ...

That superhero is a gene called TP53, and for decades scientists have known it as the “guardian of the genome.” In a healthy cell, TP53 acts like both a brake and an emergency stop button. When DNA ...

An estimated 170,000 Australians were diagnosed with cancer in 2025. Many people know the causes of cancer are partly genetic. But how do your genes, which contribute so much of what makes you you, ...

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 ...

There are some genes that can promote cancer; they are sometimes called oncogenes, and in tumor cells, mutations are often found in these genes. When they are functioning normally, oncogenes are often ...

Human cells usually contain two copies of most genes, one of which comes from the mother while the other comes from the father. It's long been thought that usually these two copies, or alleles of ...

Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a new study from Duke University. The findings, published in PLOS Biology, ...

Emily Kramer-Golinkoff can’t get enough oxygen with each breath. Advanced cystic fibrosis makes even simple things like walking or showering arduous and exhausting. She has the most common fatal ...

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 ...

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, ...
