tellmeGen DNA Tests

tellmeGen is a DNA testing company located in Spain. They offer DNA tests using DNA genotyping (microarray) technology. This test uses similar technology as 23andMe and AncestryDNA.

tellmeGen allows its users to download the raw DNA data file so that it can be used at third-party sites, such as the DNA analysis apps and reports available in our DNA Report Marketplace.

Useful information regarding tellmeGen DNA data

Our bioinformatics team has identified issues with some of the raw DNA data files from tellmeGen. Specifically, we found that some of the data has been aligned to the negative (reverse) strand of DNA. This assessment is based on a raw DNA data file from tellmeGen that is several years old, and it may not reflect the current state of their raw DNA data files.

Industry standards generally require that 100% of raw DNA data be provided on the positive (forward) strand. For instance, our Whole Genome Sequencing test, along with those from other major DNA testing companies such as 23andMe, Ancestry, and MyHeritage, ensures that all raw data is aligned to the forward strand.

In contrast, tellmeGen appears to provide a mix of data, with some aligned to the forward strand and some to the reverse strand. This complicates the use of tellmeGen’s raw data for accurate analysis. As a result, our bioinformatics team has observed that this strand issue frequently leads to false positives in DNA analysis apps and reports.

In 2024, we requested a more recent raw data file to determine whether this issue persists. As of now, we have not received an updated file and are therefore unable to verify if their current raw data format meets industry standards.

How To Upload tellmeGen DNA Data

If you still want to use tellmeGen data, tellmeGen data can uploaded and used with the apps in Sequencing’s DNA App Store.

1. Sign into your tellmeGen account.
2. From the user menu, goto ‘listing kits’ and then select ‘Actions’. You should see the option to download the raw DNA data.
   • If your tellmeGen account contains genetic data for two or more people, download the raw data for each profile.
   • Your tellmeGen raw DNA data will be downloaded as a zip file. You do not have to unzip the file and instead can upload the zip file into your Sequencing account.
3. Go to the ⁠Upload Center at Sequencing.com.
4. Choose the upload option under ‘Upload from My Computer’ and select the tellmeGen file that you recently downloaded to your computer.
5. Click Upload. 
   • Your tellmeGen DNA file will be securely uploaded into your Sequencing account.
   • It may take up to 15 minutes before your file appears in your account.

Congratulations! You can now use your tellmeGen data with apps in our DNA App Store.
