How to Interpret My Results

The Science Behind it

BioCertica is the first African-based direct-to-consumer genetic testing company to estimate genetic predisposition to various traits and diseases using the polygenic risk scoring methodology.

 What is a Polygenetic Risk Score?

From a genetic perspective, traits and diseases can arise in a few ways. One way is known as monogenic, meaning that one genetic mutation in one gene causes the disease. An example of this is cystic fibrosis, which is caused by a mutation in the CFTR gene. However, most traits and diseases are complex and are caused by an accumulating effect of many genetic variants across many genes and this is known as polygenic. For example, there are multiple genes (more than those shown here) that contribute to the development of coronary artery disease.  

These genetic variants are called single nucleotide polymorphisms (SNPs) and each SNP comes in different versions. These versions could contribute to a trait or disease, while others could be neutral. It’s the combination of versions of the SNPs you have that determine your genetic predisposition.

A polygenic risk score (PRS) is a type of genetic testing that gives an estimated relative risk score for how likely you are to develop a certain disease or trait by taking into account all the versions of the SNPs that contribute to the trait or disease and giving a net score.

One person may have more SNPs versions that contribute to a trait and therefore put them at a higher genetic predisposition for developing a trait while another person could have a combination of those SNP versions that puts them at a lower genetic predisposition.

 

Why Do a PRS Test?

Your genetic predisposition is known as your relative risk of developing a trait or a disease while your overall risk known as the absolute risk is a combination of the relative risk and lifestyle factors. Therefore, if you have a high relative risk for a disease and you combine that with a lifestyle that further increases your risk for the disease, you will have a high absolute risk and will likely develop the disease. However, although you cannot change your genes, you can change your lifestyle and subsequently lower your absolute risk.

On the other hand, having a low relative risk, does not necessarily protect you from developing a disease. 

Knowing your genetic predisposition can help you take actions that mitigate the risk or allow you to work with your genetic profile to enhance your life. In other cases, understanding your genetic make-up can give you a sense of acceptance.

How to Interpret My Results

 After calculating a PRS result, we get a number between -1 and 1 corresponding to a scale of genetic predisposition (highly decreased to highly increased). Based on this number we can place you on the genetic predisposition scale. To know if the genetic predisposition is a positive or a negative outcome, you need to consider the trait. For example, a decreased genetic predisposition to vitamin D absorption is not a good thing as it means you are prone to vitamin D deficiency. However, a decreased genetic predisposition to developing Type 2 Diabetes is a more favourable outcome. When you open a trait, there will be a short statement to help you interpret what your results indicate. 

To help put your results into perspective, we compare your results to other BioCertica users so that you can see where you fit in the general population. 

Additionally, under the symptoms tab, you will find common signs to look out for should the trait manifest and basic recommendations for either mitigating or treating the condition. 

In order to obtain PRS results we need to know which SNPs to consider and these come from large population studies known as Genome-Wide Association Studies (GWAS). Under the references tab, we provide the links to the peer reviewed studies that we used to build the score.

We also try to provide you with as much information on the trait as possible.

It is important to remember that these are only your genetic predispositions, not a diagnosis. If your genetic predisposition puts you at risk for developing a condition and you are experiencing the associated symptoms, you may have the condition, but you will need to consult your practitioner for a diagnosis.

Summary outcomes

Here is a quick guide to help you identify which of your traits may be of concern or not.

Cells marked in red highlight potential concerns, while green indicates a good outcome. Blue represents a result that is neither good nor bad but has some potential to be concerning.

 What Should I do with this Information? 

How to take action based on the genetic predisposition depends on the trait. We provide a basic outline in the recommendations section of the app for each trait but we highly recommend that you go to a qualified practitioner to help you piece together the actionable outcomes based on your genetics.
