Why do I see more SNPs on my SelfDecode account than in my downloaded DNA file?
Why Do I See More SNPs on My SelfDecode Account Than in My Downloaded DNA File?
Your downloaded DNA file contains only the SNPs directly tested by our DNA microarray chip. Your SelfDecode account shows additional SNPs estimated through genetic imputation, which provides a more complete picture of your genetics.
What's the Difference?
- Your downloaded file: Contains only SNPs that were directly tested
- Your SelfDecode reports: Include directly tested SNPs plus additional SNPs estimated through imputation — we analyze around 200 million SNPs with our imputation process
What Is Genetic Imputation?
Genetic imputation uses statistical methods to estimate additional SNPs based on your existing genetic data and known genetic patterns in populations. This process allows us to generate more detailed health insights without testing every single variant.
Inconclusive Results
In some cases, certain SNPs may have had inconclusive results during testing (such as conflicting readings from different probes), so they're excluded from your downloadable file. However, we can often estimate these SNPs through imputation and display them on the platform.
