Bacteria is linked to metabolic diseases Obesity and diabetes are common heritable diseases, but the risk of disease lies in complex interactions between our genes, our environment, and our gut bacteria. Our relationship to microorganisms can be simply put as complicated. While some microorganisms can cause deadly infections, others play essential roles in human health. Gut…

The gold standard for diagnosing endometriosis has always been through a laparoscopy. Yet, recent advances in the field of genetics have identified biomarkers in the genome which could help identify women who are at risk of developing endometriosis. It affects females with infertility, but genetic testing may be the answer. What is endometriosis? Endometriosis is…

Not all Genetic Tests are the same Each person carries 4-5 million genetic variations called polymorphisms. Most of these genetic variations do not cause any disease. Analysis of these common variations can provide very interesting insights on our ancestry, and can also be used to predict future diseases. However, the accuracy of these predictions depends…

What causes Down syndrome? Down syndrome, also known as trisomy 21, is a condition characterized by a delay in growth, a distinct set of facial characteristics, and intellectual disability[1]. This is caused by imbalances in gene expression resulting from having three copies of chromosome 21, instead of the normal two copies (Figure 1). Figure 1. Down…

Antibiotic Resistance: The Clues Are in Our Genes Doctors are often faced with the challenge of treating children that have a fever without an apparent cause because fevers are a symptom of both bacterial and viral infections. As a precaution, many of these children are given antibiotics even though antibiotics are completely ineffective against viral infections….

Last month the United Kingdom became the first country to back three-person in vitro fertilization (IVF), a technique that creates babies using DNA from 3 individuals. This technique is especially controversial because the subsequent genetic alteration to the embryo affects the germline (i.e. germ cells that have genetic information), that will be passed on to…

What is Tecta? How does Tecta work? Tecta (pantoprazole) is prescribed to treat gastrointestinal ulcers, or for gastroesophageal reflux disease (GERD), which includes heartburn and acid reflux, and reflux esophagitis. Tecta is part of a family of drugs called Proton Pump Inhibitors (PPIs). These drugs block Proton Pumps, and reduces stomach acidity to prevent ulcers,…

[sociallinkz] Confused when choosing a genetic testing provider? You came to the right place! This post aims to provide the answers to questions you may have when deciding which genetic testing provider is best for you. Common Concerns When Choosing a Genetic Testing Provider “I’m concerned about my risk of cancer and looking for a…

Why a new study will make you think twice before reaching for the saltshaker How Autoimmune Diseases Start Autoimmune diseases are disorders that result from the body initiating an inappropriate immune response either to its own proteins, or to substances that are normally found within the body. Common autoimmune diseases include celiac disease, Crohn’s disease,…

Many guys have a soft spot for their cars and garages, and put in a significant amount of effort to keep them in immaculate condition. So why don’t they keep their own bodies in such immaculate condition as well? Too many successful men are dying prematurely due to conditions like heart attacks that can be…

How drugs affect the body Many commonly used drugs can be helpful for most while causing adverse reactions in others. Medication needs to be absorbed and then metabolized into a biologically active form or inactivated at a certain rate. Drug absorption and secretion (i.e. pharmacokinetics) can be affected by certain genetic variations that may render…

What is genetic testing? Rather than diving into scientific terminology to explain genetic testing, let’s start with an analogy of building a house to describe a person’s DNA. DNA is the blueprint for building all the functional cells, tissues, organs in an organism as well as coordinating all the functions. The first step to building…
