Mutation Load: Understanding Genetic Variations and Their Impact on Health

Introduction to Genetic Variations and Mutation Load

The Blueprint of Life: An Overview of Genetics

Your genetics are the unique qualities and traits passed down to you from your parents. These genetics or genes exist in your inherited chromosomes. Chromosomes come in pairs; each person has 46 in total (23 pairs). You received one of each pair of chromosomes from your mother and father. With these, you were given randomly selected DNA (genes) segments, instructing your cells on how to make your body function properly.

In this blog, we’ll look at the following topics:

The Theriome 12 Metabolic Blood Test: A Holistic Health Assessment

At Theriome, we offer a unique method for evaluating health that distinguishes us from other at-home microbiome blood tests. We concentrate on 12 crucial aspects of metabolism to give you a thorough understanding of your overall health. These encompass:

  • Liver Health
  • Gut Health
  • Cardiovascular Health
  • Inflammatory Score
  • Environmental Toxin Exposure Index
  • Neurocognitive Index
  • Nutritional Index
  • Mutation Load
  • Aging Index 
  • Integumentary Health
  • Reproductive Health
  • Mitochondrial Health

For each pillar, you’ll receive your results as a personalized score ranging from 1 to 10, enabling you to take charge of your health journey.

Zooming in on the Mutation Load as a Crucial Metabolic Pillar

The Mutation Load pillar of Theriome 12 works to identify genetic variations in your bloodstream that have the potential to impact your health, making you more susceptible to certain diseases and infections and disrupting your body’s response to treatments.

The Science Behind Genetic Mutations

What are Genetic Mutations and How Do They Occur?

Genetic mutations occur when your DNA sequence changes during cell division (the process of your cells copying themselves to expand their population).

Genetic mutations play an important role in human evolution. This means that as genetic mutation occurs in an individual, it will be carried in their egg or sperm onto their offspring.

Different Types of Genetic Variations: From SNPs to Large-scale Mutations

There are three primary types of genetic mutations: base substitutions, deletions, and insertions.

Base Substitutions

Base substitutions are the simplest gene-level mutation. They occur when one base pair is replaced by a different base pair. These can be helpful or harmful to your health. They may also have no effect at all. For instance, if a silent substitution mutation occurs, the protein’s function won’t change, resulting in no impact on the body. 

Complications may occur with missense substitution mutations that code for the wrong protein or nonsense mutations that stop protein creation too soon, creating a non-functional protein. One example of a harmful effect of base substitutions is the development of sickle cell anemia, a genetic disorder that causes a shortage of red blood cells.


Deletions occur when one or more nucleotides are lost from a DNA segment, thus deriving the name from “deleted.” A deletion mutation changes the function of the proteins being produced by the affected DNA segment. 

The disruption of protein functions can lead to several health complications, including birth defects in a person’s offspring and intellectual or physical disabilities. Other health conditions may occur as well, such as deletion syndrome, cystic fibrosis, Turner syndrome, and Williams syndrome, all of which have the potential to alter a person’s quality of life significantly.


On the contrary to deletion, insertion is a mutation type that involves a DNA segment receiving one or more nucleotides. The outcome of this process may cause little to no effect or disrupt the gene’s functions. 

Insertion-induced gene dysfunction is linked to several health conditions, including Fragile X Syndrome, Huntington’s Disease, cystic fibrosis, and myotonic dystrophy. Fragile X Syndrome is among the most common disabilities inherited due to mutations.

The Role of Environment and Lifestyle in Genetic Changes

Your environment is more likely to influence your personality and behavioral traits independently from your genes. However, it can still affect your genes’ DNA sequences and activity levels

When this happens, the proteins made from your genes can alter and change your traits as a result. We’ll look more into the specific lifestyle factors that can influence your genes later on. As a quick breakdown, these include variables such as UV radiation exposure, smoking, diet, and stress.

Delving into the Mutation Load Index

What the Index Measures: Key Genetic Variations and Their Significance

The Mutation Load Index looks at your genes, chromosomes, and proteins to identify changes or abnormalities. This information determines your risks for developing certain genetic disorders and whether or not you carry specific gene mutations that can be passed to your offspring.

Interpreting the Results: Deciphering Your Genetic Profile

Your blood test includes information on your genes, which can be studied for any mutations. Single base pair mutations can be identified through direct sequencing, where the lab looks at each base pair in sequence and compares these to the normal gene. 

Mutations can be harmless, but they also have the potential to cause changes to gene expression or encoded protein, which can increase your risk of severe health conditions like certain cancers, neurological disorders, and cardiovascular disease.

Implications of High Mutation Load

Genetic Predispositions to Certain Diseases and Conditions

Mutations to your DNA sequences that change your genetic makeup can be inherited by your offspring, making them more susceptible to particular health problems, known as genetic predispositions. Certain cancers, diabetes, obesity, heart disease, and celiac disease, among others, are linked to genetic predisposition.

The Influence of Genetic Variations on Treatment Responses

Genetic variations can alter how your body’s responds to certain drugs and medications. They can make these ineffective (drug resistance) or create adverse side effects, rendering the treatment method unproductive. Mutations can alter the function of proteins and create metabolic dysfunction, which affects how well drugs can absorb and take effect in your system.

Lifestyle Factors That Can Exacerbate Genetic Risks

UV Radiation Exposure

UV radiation can break down DNA strands, which can damage or kill the cell, leading to gene mutation.


Exposure to the chemicals in cigarette smoke can change the chemical behavior of DNA bases, causing base substitutions to occur, leading to mutation.


The nutritional value of your diet can interact with chromosomes and influence your overall health, including fertility and your risk of certain diseases. For example, research has found that fruits and vegetables can decrease heart disease risks.


Stress, in general, is an influential factor in your health. Numerous studies show a connection between stress and shorter telomeres, a chromosome component associated with the risk of heart disease, diabetes, and cancer.

Personalized Medicine: Tailoring Treatments Based on Genetics

The information provided in your customized Mutation Load index informs you about potential health concerns. It detects genetic changes in your blood that could affect your well-being, potentially increasing your vulnerability to specific illnesses and infections and influencing how your body responds to treatments. Armed with this knowledge, you can make better decisions regarding your diet and lifestyle and tailor your healthcare to match your unique requirements.
