The Hidden Gene Behind Immune Diseases

Scientists at the Wellcome Sanger Institute in England are suggesting that the role of genetics in the risk of having an immune disease could be missed during research. These scientists and their collaborators have discovered that the contribution of genetic variations in disease risk lies not only in genes but in the molecular “switches” that control these genes as well.

Genetic Code Key to More Effective Depression Treatments

The year is now edging into that time where thousands of people begin to feel a little blue and just want to curl up under a blanket. This is called Seasonal Affective Disorder and can be treated with a mild antidepressant until it subsides in the spring but what about those whose constant struggle with depression has them feeling like every treatment has let them down?

Crave Sweets? It Could Be Due to Your Genes

The gene FGF21 provides the instructions for creating a hormone of the same name; it is linked with food regulation in rodents and nonhuman primates. This new insight suggests FGF21 might actually moderate some appetites in humans as well. Interestingly, the work also suggests that the liver, which secretes the FGF21 hormone and controls insulin resistance, could be playing a larger role in snack management because it produces this hormone and communicates with the brain.

Diet or DNA: Are Food Allergies Genetic?

Food Allergies & Genes

As we have explored in our past blogs, there are a number of physical and behavioral traits that are determined by your DNA.

But are you aware of how genetics can determine food allergies, too?

Today, we’re exploring how allergies can come to affect an individual, and how much DNA plays into it.

Can a Baby Have a Different Eye Color Than Both of His or Her Parents?

Eye Color

Despite the fact that most people study basic genetics in high school biology class, when it comes time for the practical application of these studies in real life, it can be difficult to remember the basics of genetics.

For example, one question we field sometimes when people consult us about paternity DNA testing? “Can two blue eyed parents have a brown eyed baby?”

There is definitely some confusion when it comes to this topic! Read on for the answer.
