Inherited genetic mutations play a major role in about 5% to 10% of all diseases including cancers. If you have a family history of certain diseases, you may have an increased risk of developing that disease and may be passed down to children. Genetic testing is a tool used to identify those hereditary mutations in our DNA that may indicate a predisposition for certain cancers or health conditions. The Viazoi test offers hereditary predisposition profiling on 94 genes for over 145 diseases.
According to the American Cancer Society, the lifetime risk of developing cancer is 42% (1 in 2) in men and 38% (1 in 3) in women.

A DNA or deoxyribonucleic acid is a molecule that encodes genetic information for the development and functioning of living organisms. DNA is composed of chains of subunits that are called nucleotides (also called “bases”). There are four nucleotides: adenine (A), cytosine (C), thymine (T) and guanine (G). The specific order of these nucleotides in a DNA molecule is the DNA sequence and encodes the genetic information, much how the specific order of letters in a word conveys information to readers.
A genome is the entire set of genetic material for an organism. The human genome consists of about 3 billion base pairs of DNA across 23 pairs of chromosomes, which are present in two copies in both men and women. While most cells in our body have two copies of each chromosome, sperm and eggs carry only one copy of each chromosome. When a sperm fertilizes an egg, the embryo now contains two copies of each chromosome, one from the father and one from the mother. Consequently, each person has two copies of every gene carried on a chromosome: one inherited from their father and one from their mother. More than 99 percent of the human genome is the same in all people. That means that differences, also known as variants, in less than 1 percent of our genome accounts for the vast diversity of humans across the globe.
Most genes encode proteins, which are a group of complex molecules that perform critical roles in our cells and bodies. The current estimate is that the human genome, which is all the DNA sequences in our cells contains approximately 25,000 genes.
DNA sequencing identifies an individual’s variants by comparing the DNA sequence of an individual to the DNA sequence of a reference genome maintained by the Genome Reference Consortium (GRC). There are different ways that one person’s DNA sequence can differ from the reference DNA sequence, some of which are:
- Deletions are when there are missing nucleotides, relative to the reference sequence.
- Substitutions are when multiple nucleotides are altered from the reference sequence.
- Single nucleotide polymorphisms (“SNPs”, pronounced “snips”) are DNA sequence variations that occur when a single nucleotide differs from the reference DNA sequence.
- Insertions are when additional nucleotides inserted in a DNA sequence, relative to the reference sequence.
- Structural variants are changes where large sections of a chromosome or even whole chromosomes are duplicated, deleted or rearranged in some manner.
Variants and Variation
The average person’s genome has millions of variants. Some variants occur in genes but most occur in DNA sequences outside of genes. A small number of variants have been linked with diseases, but most variants have unknown effects. Some variants contribute to the differences between humans, such as different eye colors and blood types.
Classification of Variant types:
The American College of Medical Genetics and Genomics (ACMG) has developed guidelines for the classification of DNA sequence variants:
- Pathogenic and likely Pathogenic (VLP) is a genetic alteration that increases an individual’s susceptibility or predisposition to a certain disease or disorder and has been previously reported and recognized to have a high association with the disorder.
- VUS (Variant of Unknown Significance) is a variant form of a gene, which has been identified through genetic testing, but whose significance to the function or health of an organism is not known.
- Likely Benign (VLB) is a sequence variant for which there is strong evidence against pathogenicity.
- Benign is a sequence variant for which there is very strong evidence against pathogenicity. Benign alterations are not routinely included in results reports.
Understanding the effects of variants is a very complicated process. While there are many publicly available sources of information about variants and their classification based on ACMG guidelines that link variants to diseases, knowledge about variants is constantly evolving and inconsistencies and inaccuracies can be found in these sources. Any health-related matters should be directed to your doctor or another qualified medical professional.

Genetic testing is a tool used to identify those hereditary variations in our DNA that may indicate a predisposition for certain health conditions including cancers. Results will not confirm whether or not you will develop cancer.
- A large percentage of people will receive a negative result. This indicates that a specific variation(s) were was not identified.
- A small percentage of people will receive a positive result. This indicates the presence of a specific variation(s).
The results of genetic tests are not always straightforward, which often makes them challenging to interpret and explain. Therefore, it is important for individuals and their families to ask questions about the potential meaning of genetic test results both before and after the test is performed. When interpreting test results, your primary care physician will consider a person’s medical history, family history, and the type of genetic test that was done.
Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can identify inherited mutations or predispositions that may have health implication. More than 1,000 genetic tests are currently in use, and more are being developed.
Most cases of breast cancer are not caused by inherited genetic factors. These cancers are associated with somatic mutations in breast cells that are acquired during a person’s lifetime, and they do not cluster in families.
In hereditary breast cancer, the way that cancer risk is inherited depends on the gene involved. For example, mutations in the BRCA1 and BRCA2 genes are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase a person’s chance of developing cancer. Although breast cancer is more common in women than in men, the mutated gene can be inherited from either the mother or the father.
Viazoi offers doctor-reviewed and approved genetic testing that can profile up to 94 genes. These 94 genes have been found to have a correlation with over 100 health conditions and the results can give you important information in order to develop a proactive wellness regimen with your doctor. In addition to profiling more genes, we offer genetic testing with every purchase. We, at Viazoi, want to support your wellness journey by being there when you need it.
Results from the Viazoi testing will not give you a diagnosis or mean that you will definitely develop cancer in your lifetime. Your actual risk is based on both genetic and non-genetic factors.

ViaGene, a product of Viazoi, is a personal genetic testing resource focused on preventive and personalized healthcare. ViaGene tests identify known genetic variants in your DNA using provided saliva sample. The genetic risk profiles are not diagnostic in nature and should not be used as one. Results with greater risks for certain conditions do not necessarily mean that the patient will get that condition either now or in the future. It is important to keep in mind that genes do not act by themselves in determining your health condition and longevity. DNA is only one of the factors that matter, and genetic testing information should mainly be considered to learn ‘how DNA relates to these traits’. Environmental factors and lifestyle-related factors heavily influence the outcome of many health conditions. Thus, ViaGene assesses genetic variations to determine what you are genetically predisposed to.
Additionally, science and knowledge in the genetic testing area change quickly, and this website should not be considered error-free or as a comprehensive source of all information on a given topic.
Customers who purchase products of Viazoi should do so with the understanding that health results are not and will not be made available to them.
