Predict Your 23andMe Variants

Upload your 23andMe or AncestryDNA raw data file. We'll match your variants against ClinVar and show you what's known about each one. Everything happens in your browser — your raw data never leaves your computer.

100% client-side. Your raw genotype file is parsed entirely in your browser using JavaScript. Nothing is uploaded. Nothing is logged. We only use your matched variants (≤10 items) to display results. Close this tab and your data is gone.
