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…
If you’ve had genetic testing done, you may have seen the word “carrier” in your report. For many people, this term sounds alarming—but in most cases, being a carrier does not mean you are sick. Here’s a simple explanation of what it means and why it matters. What is a…
Getting a genetic test result can feel overwhelming—especially when you see a term like “Variant of Uncertain Significance” (VUS). If you’ve received a VUS result, the good news is this: it does not mean you have a disease, and it does not automatically mean your family members are at risk.…
If you’ve been searching nonstop for answers about genetic testing, you’ve probably seen two options come up again and again: exome sequencing and genome sequencing. They sound similar, and both can be powerful tools -but they’re not the same, and choosing between them can feel overwhelming. Here’s a clear, simple…
Pharmacogenomics (pronounced far-muh-koh-juh-NOH-miks) is the study of how your genes affect the way your body responds to medicines. In simple terms, it helps explain why the same drug can work well for one person, cause side effects in another, and do very little for someone else. Your body uses proteins—often…
Genetic counseling helps you understand your genes, assess inherited risks, and prepare for informed health and family planning decisions. Genetic counseling is a professional service that helps individuals and families understand how genetics may affect their health, reproductive decisions, or the health of other family members. It is provided by…
The Moment Medicine Realized It Was Only Reading the Headlines For nearly a decade, clinical genetics revolved around a tidy, confident idea: if you can read the exome, you can explain the disease. It was elegant and logical. The exome represents the 1-2% of the genome that codes for proteins,…
Family health history is one of the most powerful yet underused tools in modern medicine. Long before genetic tests, sequencing platforms, or precision therapeutics, families carried forward a living record of health and disease through shared stories, diagnoses, and outcomes. Today, that record—when carefully observed and thoughtfully interpreted—remains indispensable for…
Alzheimer’s disease is often spoken about as an inevitable part of ageing, something that slowly emerges from a complex mix of lifestyle, environment, and chance. Over the past three decades, however, scientists have known that our genes play a major role in shaping who is most at risk. Among these…
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.…
