Frequently Asked Questions

What is whole genome sequencing (WGS)?

Whole Genome Sequencing is just that: we sequence billions of letters of your DNA, a long chain of As, Ts, Cs and Gs. Your 40.000 genes are encoded in this chain of letters and we analyze your sequence looking for changes or variants in the genes identifying what makes you unique.

What is NGS?

NGS stans for Next Generation Sequencing, and is used to refer to describe all the technologies used to massively scale up any nucleic acid on a large scale.

What is DNA?

DNA is the genetic blueprint for life. It’s a complex molecule found inside every cell in our body and contains all the instructions necessary to create and maintain life. DNA resembles a twisted ladder and is made up of four chemicals – Adenine, Thymine, Guanine and Cytosine – that pair together in very specific ways: A with T, C with G. The whole sequence of these chemicals comprises our genetic code, our genome. A single DNA molecule contains about 6 billion A’s, T’s, C’s and G’s. That is, you have heard correctly, a billion. In fact, if you could deploy a DNA molecule it would measure almost 2 meters.

DNA is not dispersed in our cells, it is carefully packaged in structures called chromosomes. We have 46 chromosomes in total. Half inherited from our mother and the other half from our father. Located in these chromosomes are segments of DNA called genes; we have more than 40,000. More than half of them contain instructions to form proteins, and it is these proteins that determine everything about us, from the color of our eyes to our susceptibility to diseases.

Why sequence the whole genome?

Because it is the most complete genetic test and therefore the one providing more information about the genetic characteristics of each person, achieving findings that other tests would not be possible.

In our blog article 5 reasons to sequence your genome we give you only some of them.

What are the differences between Whole Genome Sequencing and exome sequencing?

Whole Exome Sequencing (WES) analyzes the exome, the part of the genome that consists entirely of exons, which are the coding parts of the genome’s proteins. Currently, WES covers around 20,000 protein coding genes, and research unlocks more each year. With the sequencing of the complete exome we only obtain 2% of the genome.

On the other hand, Whole Genome Sequencing (WGS) achieves 99%.

Does Veritas Intercontinental also offer Genetic Counseling?

Yes, in fact our doctors are recognized experts in the field of genomic medicine. We offer Genetic Counseling before and after the completion of all our tests. During the previous advice we see which test is the most appropriate for you and we explain its scope, and in the later we review your results and we offer you an action plan based on your genetics.

We can also give support to medical specialists if they need it.

Do I need to travel to receive the genetic counseling service?

It is not necessary, we offer the personalized genetic counseling service through our online platform with the team of genetic advisors of Dr. Luis Izquierdo. You can also go to our headquarters in Paseo de la Castellana 101 if you prefer.

When is it recommendable to do a genetic analysis?

Conduct a genetic analysis test is recommended whether you are a healthy person or have symptoms or family history as it allows you to know unique and personal characteristics to live longer and improve your quality of life. It is a useful resource to be able to take personalized prevention measures as well as action plans to have a higher quality and quantity of life.

To whom are the services offered by Veritas Intercontinental aimed?

The genetic analysis of Veritas Intercontinentalare both for clinical application and for completely healthy individuals who seek to have a greater and better quality of life.

Is it bad to be a carrier of a genetic mutation?

Each person can present alterations and variations in their DNA that give them characteristics that make them unique. Detecting these variations is a benefit since it will help to establish guidelines and opportune measures to reduce the possibility of developing the disease and / or treat it in an anticipated and more effective way.

Am I going to suffer from a certain disease because I am a carrier of a genetic disease?

No, being a carrier of a disease of genetic origin means that it is a disease that you have inherited and that is in your genes, which you could get to transmit to your children.

Can my genome change over time?

No, that is why we say that it is a resource for your whole life and that it can be consulted over time to know new findings that have been produced thanks to the advance of scientific knowledge.
