Decoding Us
A collaborative platform for genetic genealogy and population research — Y/mtDNA haplogroup trees, a public variant browser, and privacy-preserving relative discovery.
What is Decoding Us?
Decoding Us is an open, collaborative platform for genetic genealogy and population research. You own your genetic data; the shared trees and catalogs are built openly from what the community contributes.
Open haplogroup trees
Y-DNA and mtDNA phylogenies rebuilt de novo from real genotypes — not curated by hand — so every branch is anchored in the sequences that define it.
Public variant catalog
A browsable catalog of Y and mitochondrial variants and the reference samples that anchor them, cross-referenced to the trees and the literature.
Private discovery & research
Find relatives and collaborate on research with privacy-preserving matching — no genotypes leave your control, and every share is by consent.
How to participate
Whether you're just curious or ready to contribute your own results, there's a way in.
Explore
Browse the Y-DNA and mtDNA trees, search the variant catalog, and read the reference samples — all open, no account needed.
Contribute your DNA
Run your whole-genome or Y/mt sequencing data through the Navigator client to place yourself in the trees and help refine them for everyone.
Own your data
Your results live in your own AT Protocol repository (PDS). You decide what is shared, with whom, and can withdraw it at any time.
Collaborate
Join research projects, compare notes with the community, and discover genetic relatives — always on your terms.
