A simple guide to DNA testing, Whole Genome Sequencing, ancestry, health and raw DNA data

Your DNA is more than a genetic code. It can tell a story about your ancestry, health, lifestyle, and much more.

DNA testing in India has changed significantly over the years. What was once mainly associated with ancestry or paternity testing is now part of a growing field of consumer genomics.

Today, DNA testing can provide information related to ancestry, health, nutrition, fitness, pharmacogenomics, and genetic variation.

Not all DNA tests are the same.

Some tests focus mainly on ancestry. Others are designed for health and lifestyle reports, while some services analyse raw DNA data that you already have. There are also tests based on Whole Genome Sequencing (WGS), which analyse a much larger portion of your genetic information.

So, how do you know which type of DNA test is right for you? Let's understand the basics.

Before choosing a DNA test, it helps to understand the technology behind it. There are two common approaches discussed in consumer DNA testing: microarray/genotyping and Whole Genome Sequencing (WGS).

Instead of examining the whole genome, it checks a specific set of genetic markers. The source material describes microarray testing as examining around 6.5 lakh selected markers.

This approach can be useful for specific ancestry, health, and lifestyle applications, depending on the test and the reports offered. However, it does not provide the same type of genome-wide data as Whole Genome Sequencing. This approach can be useful for specific ancestry, health, and lifestyle applications, depending on the test and the reports offered. However, it does not provide the same type of genome-wide data as Whole Genome Sequencing.

Whole Genome Sequencing takes a much broader approach. Instead of testing only selected genetic markers, WGS is designed to read DNA across the genome. GenoConnect uses WGS and analyses approximately 3 billion base pairs of human DNA, with coverage options extending up to 30×. But more data is only one part of the story. The usefulness of a DNA test also depends on how the data is interpreted, which reference populations are used, how reports are generated, and how the results are presented to the user.

Getting a DNA sample does not have to be complicated. GenoConnect uses a cheek swab, allowing you to collect your own DNA sample from the inside of your cheek. The process is simple and non-invasive, and the collected sample can then be submitted for genetic analysis.

Different people may have different requirements, which is why GenoConnect offers multiple sequencing options:

1. 1× WGS

2. 5× WGS

3. Hybrid 5× WGS + 100× WES

4. Up to 30× WGS

This gives users different options depending on the type of genomic information they want to explore.

When people think about DNA testing, ancestry is often one of the first things that comes to mind. But ancestry can be much more than simply finding out that your DNA is “South Asian” or belongs to another broad geographical region.

GenoConnect provides ancestry-related features including:

1. Modern ancestry

2. Ancient ancestry

3. Haplogroups

4. PCA plots

5. FST distance

The supplied information also describes the use of South Asian reference data to explore historical ancestry components associated with populations such as the Indus Valley Civilization, AASI, Steppe, and Iranian Neolithic farmers.

Interested in going further back in time? GenoConnect's ancient ancestry analysis uses the AADR database and the qpAdm technique, according to the supplied information. The source describes an AADR database containing approximately 2.1 million markers and different levels of marker coverage depending on the sequencing option. The reports described in the source cover five historical periods, including the Paleolithic, Neolithic, and Early, Middle and Late Bronze Age. This allows ancestry analysis to be presented in the context of population history rather than only modern geographical categories.

Your maternal and paternal lines can also tell a deeper ancestry story.

Mitochondrial DNA (mtDNA) is passed through the maternal line and can be used to study mitochondrial haplogroups.

According to the supplied material, GenoConnect's WGS approach can provide deeper haplogroup information than conventional microarray testing.

For people interested in deep ancestry and population history, haplogroup information can add another layer to their genetic profile.

For many people, receiving their raw DNA data is just as important as receiving the final reports.

Raw genomic data can potentially be used for additional analysis with compatible platforms and tools.

According to the supplied information, GenoConnect provides 5× WGS BAM files and also allows users to upload raw DNA data obtained from other companies for analysis.

This means your DNA data can be more than a one-time report.

Instead of keeping track of multiple PDF reports, GenoConnect provides genomic information through a digital dashboard.

This gives users a central place to access their available reports and genetic information.

There is no single DNA test designed for everyone's needs. Some companies focus on health. Some focus on ancestry. Some analyse existing raw DNA data, while others provide specialised genetic tests.

Here's a simple look at some of the services mentioned in this guide.

MapmyGenome is an Indian consumer genomics company that provides personalised health information through services such as Genomepatri.

The supplied material describes its testing as genotyping/microarray-based, with a focus on areas such as disease-risk information, hereditary conditions, diet, and genetic counselling.

Xcode Life follows a different model. Instead of necessarily collecting a new DNA sample, users can upload an existing raw DNA file from services such as 23andMe or Ancestry. The uploaded material describes reports covering areas such as health, nutrition, fitness, allergy, and precision medicine. The reports depend on the information contained in the original raw DNA file.

DNA Labs India provides more specialised DNA testing services, including:

1. Paternity testing

2. Relationship testing

3. Genetic disease testing

4. Clinical DNA testing

5. Carrier and hereditary-condition testing

These services are designed for specific testing needs rather than the broader consumer genomics approach described for WGS platforms.

International consumer DNA services such as 23andMe and AncestryDNA have large global databases and offer ancestry-related and other genetic reports.

For Indian users, the availability and level of detail in South Asian reference populations can be an important consideration. The source also mentions international shipping and customs as factors that may need to be considered.

The answer depends on what you want to learn.

If you are mainly interested in ancestry, an ancestry-focused test may be enough for your needs.

If you need information about a particular hereditary or clinical condition, a specialised genetic test may be more appropriate.

If you already have a raw DNA file, a raw-data interpretation service can help you explore additional reports without collecting a new sample.

And if you want to explore ancestry, health, fitness, nutrition, and pharmacogenomics through Whole Genome Sequencing, a WGS-based platform such as GenoConnect offers that broader approach.The answer depends on what you want to learn.

Your genomic data is personal. Before testing, understand how your data is stored, processed, protected, and made available to you.

These questions can help you choose a test based on your needs rather than simply choosing the package with the largest number of reports.

Your DNA contains billions of pieces of information. The interesting part is learning how that information can be explored. From modern and ancient ancestry to health, pharmacogenomics, fitness, nutrition, and raw genomic data, DNA testing can open the door to a deeper understanding of your genetic profile. With Whole Genome Sequencing and multiple testing options, GenoConnect gives you a way to explore more of your DNA through one platform
