GenePlaza Introduction

GenePlaza is a genetic testing company that offers a series of apps to analyze your genetic data. The company was founded in 2017 by Dr. Alain Coletta and Robin Duqué. Coletta and Duqué previously worked together on InSilico Genomics S.A, a company to help researchers with genetic analyses. They founded GenePlaza helps users better understand their DNA. GenePlaza provides apps that do everything from calculating your predisposition to depression, to predicting your math ability. According to Coletta, GenePlaza is the first instance in which users can purchase apps for DNA analysis. He claims that these apps are different from full genetic reports since each app tends to focus on one trait.  Users can purchase individual apps for the traits they are most interested in. This allows for a targeted approach to learn about your genetic code but does require multiple purchases. GenePlaza users can also authorize the use of their genetic results for biological research. Learn more in our GenePlaza review!

How Does GenePlaza Work?

GenePlaza offers a myriad of DNA analysis apps, which are created by research scientists. Creating an account with GenePlaza is easy, and only requires the user’s name and email address. Once you create your free account, you use your GenePlaza login to upload your DNA data from 23andMe, AncestryDNA, FamilyTreeDNA, MyHeritage, and Gencove. If you don’t already have a DNA file, you may order a DNA test from GenePlaza. 

GenePlaza DNA tests can only be delivered to countries in Europe, but the apps are accessible by anyone in the world. Instead of using full genome sequencing, GenePlaza genotypes the DNA sample at 700,000 locations in the genome. The cost of this DNA test is $164. While AncestryDNA and 23andMe use a similar testing method, the GenePlaza test is more expensive for users.

Before we dive in the full review of GenePlaza apps, let’s get an overview of the available services. Once the genetic data has been generated or uploaded, there are currently 21 analysis apps available as of October 2020. The GenePlaza cost for apps is between €1.49 ($1.61) and €40.59 ($48). Users who order DNA tests from GenePlaza get €6 credit to use towards app purchases. Furthermore, users who upload their own genetic data get €3 credit. 

GenePlaza apps do not provide one comprehensive report, but are instead comprised of various trait-level tests, including the following:

  1. SAPDA: Infers your ancestry. Uses a pool of data from other populations to remove confounding genetic mutations for a more accurate result. 
  2. The K35 Calculator: Reports how similar your genetic data is to ancient populations from the Bronze and Iron ages. 
  3. Bronze Age DNA Test – Advance: a high-resolution DNA test, which calculates the proportion of 10 ancient gene pools.
  4. Bronze Age DNA Test – Beginner: a low-resolution DNA test, which calculates the proportion of 6 ancient gene pools.
  5. GenePlaza K29 Admixture Calculator: Uses shared allele frequencies to report your genetic similarity to various populations around the world, including West, South, East Eurasians, and Native Americans.
  6. The K5 Admixture: Measures relatedness of individuals to highly diverged populations of Eurasia, including West, South, East Eurasians, and Native Americans.
  7. Addictions: Predicts drug addiction related genetic variants.
  8. Math Ability: Reports your relative math ability compared to the rest of the population, based on a previously published scientific study.

Review of GenePlaza Apps

Sample reports are available for all GenePlaza apps, along with detailed descriptions created by app developers. Results for each of the apps are accompanied by the following disclaimer: 

DISCLAIMER: This application is not a diagnosis, a prediction, or a predisposition score. This app simply shows what your score would have been if you had participated in this study. Some applications show various graphs computed from models issued by independent studies. It is possible results contradict across models.

All GenePlaza apps are created based on data from research studies. As such, for reported results, GenePlaza cites the research paper that the results are based on. Most apps also provide a discussion section. 

For more arbitrary topics, like DNA intelligence tests, the discussion includes the history and implications of these measurements. Reports are well-cited by the relevant literature and often include detailed descriptions of the analyses. 

Review of GenePlaza SAPDA

The SAPDA report includes Allele Matching graphs, Admixture Proportions, and Genotype Similarity Index Single Population Allele Sharing. This information is used to infer the ancestry of the user. Along with the report, a comparison to other ancestry tools is also provided. Furthermore, the report explains why certain statistical tools are used instead of others, with more links to the developer’s analyses.

Results for the Depression App, Sleep Zzz, Ci-lantro vs No-lantro, Coffee Metabolism, Intelligence App, My Weight, Taste Perception, Neuroticism App, Ancestry, and Ethnicity Calculator are similar. These results typically contain a graph showing the user’s results compared to the population used in the study. Usually, GenePlaza also provides a few articles to discuss the results.

Review of GenePlaza Health Traits App

The Health Traits app has the most extensive results and includes a large number of traits to explore. Sections include potential medical diagnoses, early life factors, family history, health and medical history, and more. 

Users can explore their genetic data across different diagnoses and genetic variants. GenePlaza lists each trait, like being diagnosed with asthma, how likely you are to have that trait, and what in your genetic code contributes to the risk.

Exploring each trait also provides further insight into your results, with comparisons of your results to the population studied. Users can also look at the specific genes and single nucleotide polymorphisms (SNPs) used to analyze the data. These are further broken down into the variants contributing to your risk for a specific trait.

Review of GenePlaza Privacy

The GenePlaza terms and privacy policy are easily accessible on their website. The policy includes relevant contact information in case users have any questions or concerns. Furthermore, all relevant terms are defined for the users, such as “Genetic Data”, and “GenePlaza Kit”. They list all of the information GenePlaza collects and clearly explain the reasons for collecting the data. 

No data is shared with any third parties without the user’s consent. Lastly, users may withdraw their consent to allow GenePlaza to process their data at any time. 

Downloading Your Data

If a user purchased their DNA test, GenePlaza data is expected to be available within 8 to 10 weeks. The company specifies that once the data has been produced, users can start using the apps. Furthermore, users can keep and download their data for an independent future.

GenePlaza in the News

GenePlaza was most recently in the news after a controversy surrounding their app, “122 Shades of Gray”. The app was previously called “How Gay Are You?”. Initially, it provided a score of how genetically predisposed someone might be to same-sex attraction.

According to The Lancet, the app was based on a study about genetic variants related to same-sex attraction. The app sparked a backlash from the scientific community and was criticized in Nature, The Scientist, and Genome Context. The original authors of the study also issued a letter urging GenePlaza to take the app down. 

After an online petition on, GenePlaza initially changed the app’s name to “122 Shades of Gray”, before taking it down entirely. As such, most apps on GenePlaza disclaim that results are “not a diagnosis, a prediction, or a predisposition score. This app simply shows what your score would have been if you had participated in this study”.

Similar concerns were shared on MIT Technology Review over GenePlaza’s Intelligence App. In response, Alain Coletta, GenePlaza founder, said that these tests are safe, as long as the results are private. GenePlaza stressed that according to their privacy policy, user data is not accessible to even the app developers. 

GenePlaza Reviews

“GenePlaza gave me a means to reuse my genetic information, with a selection of diverse web apps that could analyse my DNA in different ways to tell me more about my genetic predispositions. I thought their range of web apps was fairly decent, and was pleased to see that there were more coming soon…uploading your DNA or purchasing a kit entitled you to free credit, and so some apps were essentially free.”
