Hidden inside our DNA are many short sequences that repeat again and again, like stutters in the genetic code. Most of the time, these repeats are harmless. But when they grow too long, they can disrupt how genes work and trigger serious neurological and developmental diseases. These conditions, known as…
A decade ago, decoding a person’s DNA was slow, expensive, and mostly confined to research labs. Today, something remarkable is happening in hospitals and clinics around the world: doctors can read nearly all of a person’s genetic instruction manual in days or sometimes even hours. This is called rapid whole…
Inside almost every cell in your body lives a tiny power plant called the mitochondrion. These microscopic structures generate the energy that keeps your heart beating, your brain thinking, and your muscles moving. But mitochondria carry something even more surprising: their own DNA. This small but powerful genetic code is…
Many people believe genetics is something you only think about after a diagnosis. But one of the simplest and most powerful tools for predicting health risk is already available to you: your family history. A well-recorded family health history can reveal patterns that suggest an increased genetic risk, and it…
Planning a pregnancy is an exciting time, filled with hope and new beginnings. Along with thinking about nutrition, doctor visits, and lifestyle changes, many couples today are also hearing about genetics and genomic testing. While this may sound complex, the idea is simple: genetics can help you understand certain health…
Most genetic testing today only happens after someone gets sick or has a strong family history. But scientists are now exploring a different approach: genomic screening for healthy adults, to find hidden risks before disease develops. A major pilot study in Australia offered free genetic screening to 10,263 adults aged…
Have you ever wondered why a medicine works well for one person but causes side effects in another? Or why some people need a higher dose to feel better, while others feel drowsy or unwell after just one tablet? A major reason is that our bodies do not process medicines…
When people think about disease risk, they often focus on two things: “Is it in my genes?” and “Does it run in my family?” The truth is that both genetics and family history matter, and they work best when used together. Understanding this combination can help people make smarter choices…
Carrier screening is a genetic test that helps identify whether a person is a carrier of an inherited genetic condition. A carrier is usually healthy and has no symptoms, but can still pass a non-working gene copy to their child. Carrier screening is most useful when planning a pregnancy, because…
Preventive healthcare has traditionally relied on a simple approach: wait for symptoms, confirm a diagnosis, and then treat the disease. While this model has saved countless lives, it often detects illness only after damage has already begun. Whole Genome Sequencing (WGS) has the potential to change that approach by helping…
Researchers have identified a rare genetic variation that seems to reduce how much people smoke,…
A new study looked at what people actually do after getting important health results from…
For many children with rare neurological conditions, the path to a diagnosis can take years.…
