TenDNA is a web-based platform that transforms raw DNA data into comprehensive, science-backed health reports. The service is designed for people who have already completed consumer genetic testing and want to gain deeper insights into how their genetics may influence health, nutrition, lifestyle, and wellness.

The platform supports raw DNA files from the world's most popular direct-to-consumer genetic testing providers:

• 23andMe

• AncestryDNA

• MyHeritage

• FamilyTreeDNA

• Genotek

Unlike many genetic analysis services, TenDNA does not require account registration. Users can upload their DNA file, generate a report, and immediately download the results.

Comprehensive 250-Page Health Report

The flagship report contains more than 250 pages of personalized genetic analysis based on the uploaded DNA file.

The report goes far beyond simple disease risk estimates and covers a broad range of health-related topics, including:

• Genetic predisposition to common diseases

• Vitamin metabolism

• Micronutrient requirements

• Methylation and homocysteine

• Neurotransmitters and hormones

• Oxidative stress

• Mitochondrial function

• Gluten and lactose intolerance

• Memory and cognitive traits

• Diet effectiveness

• Obesity and metabolism

• Omega-3 metabolism

• Cardiovascular health

• Autoimmune diseases

• Cancer-related genetic markers

• Mental health predispositions

• Drug, alcohol, and tobacco dependence

• Fertility and reproductive health

• Inflammation

• Immune system characteristics

Rather than presenting isolated genetic variants, TenDNA combines thousands of SNPs into easy-to-understand reports that help users explore potential genetic influences on their health and lifestyle.

Scientific References for Every SNP

One of the key principles behind TenDNA is scientific transparency.

Every reported genetic variant (SNP) includes references to published scientific literature, allowing users to review the evidence behind each interpretation.

The platform links reported associations to peer-reviewed publications and widely recognized biomedical research databases, helping users understand where each conclusion originates rather than relying on unexplained genetic scores.

Privacy by Design

Privacy is a core part of the platform architecture.

• Uploaded DNA files are processed in real time.

• Raw genetic files are never stored on the server.

• No registration is required to generate a report.

• Users immediately receive their generated report after processing.

This privacy-first approach minimizes long-term storage of sensitive genetic information while making the service accessible without creating an account.

Free DNA Format Converter

TenDNA also includes a free online DNA format converter for users who need to transfer raw genetic data between different testing platforms.

The converter supports multiple popular formats and helps improve compatibility between services without requiring any software installation.

For developers and researchers, the converter is also available as an open-source project on GitHub:

https://github.com/milaza/dna-raw-data-converter-23andme-myheritage-ancestry/

The repository includes documentation, sample files, implementation details, and examples that simplify working with consumer DNA data formats.

Open Science

To improve transparency, reproducibility, and long-term accessibility, the DNA format converter has been archived with permanent Digital Object Identifiers (DOIs) in two independent scientific repositories.

DOIs:

• Figshare: 10.6084/m9.figshare.33097868

• Zenodo: 10.5281/zenodo.21628883

These permanent archives ensure that the software can always be cited and accessed by researchers, developers, and the scientific community.

Registered in bio.tools

The DNA converter has also been accepted into bio.tools, the ELIXIR-supported international registry of bioinformatics software and data resources. The registry is widely used to improve the discoverability and interoperability of life-science software tools.

Built for Everyone

TenDNA is intended for:

• Individuals interested in preventive health

• Genetic genealogy enthusiasts

• Researchers working with consumer DNA datasets

• Healthcare innovators

• Bioinformatics developers

• Students learning about human genetics

Whether you are exploring your ancestry test results or building bioinformatics workflows, TenDNA provides practical tools for analyzing and working with raw genetic data while maintaining a strong focus on privacy, accessibility, and scientific transparency.
