For many people with rare or unexplained conditions, getting a clear diagnosis can take years. This long journey—often called the diagnostic odyssey—may involve multiple doctor visits, repeated tests, and lingering uncertainty. Advances in genetic testing are changing this, and whole genome sequencing (WGS) is emerging as one of the most…
Most of us grow up thinking of genetic conditions as something rare—something that happens “in other families” or only when there is a known history of disease. The truth is more surprising: many healthy people unknowingly carry genetic changes that can be passed on to their children. This is where…
The NHS in England has launched a first-of-its-kind national genetics programme to help people at high inherited risk of cancer receive ongoing checks, tests and personalised care. This new initiative centres on the NHS National Inherited Cancer Predisposition Register, a database of people whose genes put them at higher risk…
A patient undergoes whole genome sequencing to understand unexplained seizures. The analysis provides the answer. But it also reveals something else – a pathogenic variant associated with sudden cardiac death. The seizures are treatable. The cardiac risk, once invisible, is now preventable. No one asked that second question. But the…
Cardiac genetic testing is rapidly emerging as one of the most important tools in modern heart health care—especially for people with a family history of heart disease or unexplained cardiac problems. At its core, this type of testing looks at your DNA to identify specific gene changes that can increase…
Imagine going for a test to answer one simple question ‘why am I sick?‘ and discovering something entirely unexpected. That is what can happen in modern genomics. When doctors sequence a person’s DNA to look for the cause of a specific condition, they sometimes uncover incidental findings: genetic information that…
Genetic testing has quickly moved from being something only used in hospitals for rare diseases to something many people now consider as part of routine health planning. You may have heard friends talk about “getting their DNA tested” or seen news about genetics helping doctors detect disease earlier or choose…
Imagine doing everything “right.” You eat reasonably well, you stay active, you don’t smoke. And yet, your cholesterol stays stubbornly high—sometimes very high. For many people, this isn’t about willpower or lifestyle. It’s about genetics. One of the most common inherited conditions affecting cholesterol is familial hypercholesterolemia (FH). It causes…
Have you ever wondered why a medicine works perfectly for someone else, but gives you side effects or doesn’t work at all? This is more common than people think. One important reason is genetics. Your DNA influences how your body breaks down medicines, how strongly they act, and whether you…
Cancer is not just one disease. Even two people with the “same” cancer type—such as breast cancer or lung cancer—can have very different cancers at the genetic level. That is why modern cancer care is moving beyond looking only at where the cancer started, and toward understanding what is happening…
