Most of us visit a doctor only when we feel unwell. Traditional healthcare has largely been reactive—treating disease after symptoms appear. But genomics is helping change that approach. Today, genetic and genomic testing can sometimes identify health risks early, allowing people to take preventive steps before illness develops. This 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…
Consanguinity means marriage or having children with a close biological relative, such as a first cousin or second cousin. In many communities around the world, consanguineous marriages are culturally accepted and can be common. While most children born to related parents are healthy, consanguinity is important in genetics because it…
When people hear the word “mutation,” they often think it automatically means cancer. In reality, mutations are simply changes in DNA, and they are a normal part of biology. Some mutations are harmless, some can increase cancer risk, and some directly drive cancer growth. A key point in understanding cancer…
