This page on 23andMe versus deCODEme seeks to compare the autosomal DNA test offerings from 23andMe and deCODE genetics. Note that the 23andME data refer to the version 2 chip. The information has not yet been updated to reflect the changeover to the version 3 chip which was offered from November 2010 onwards.

Overview

23andMe

  • Uses customized 550K SNP chip from Illumina
  • Tests 578,320 autosomal DNA SNPs
  • Tests 1,800 Y chromosome SNPs
  • Tests 14,000 X chromosome SNPs
  • Tests 3,000 mtDNA SNPs
  • Ancestry Painting attempts to predict from which of three regions of the world your ancestors came (Europe, Africa, Asia)
  • Ancestry Finder attempts to predict from which countries of the world your ancestors came
  • Native American Ancestry Finder attempts to predict whether a person has NA Ancestry in the last five generations
  • Global Similarity illustrates to which countries or ethnic groups one is most closely related
  • Family Inheritance: Advanced Lab graphically illustrates the matching DNA segments between customers
  • Gives information based on scientific studies about medical conditions to which one might be predisposed
  • Gives information in regard to Mendelian disease carrier status
  • Gives information based on scientific studies about individual traits
  • Allows comparisons to other people using Relative Finder
  • Customers can download their raw data but only if they have ordered the Complete Edition
  • Does not allow upload of raw data from other companies

deCODEme

  • Uses Human1M SNP chip from Illumina
  • Tests 1,072,820 autosomal DNA SNPs
  • Tests about 858 Y chromosome SNPs
  • Tests 40,097 X chromosome SNPs
  • Tests 173 mtDNA SNPs
  • Tells which regions of the world your ancestors came from
  • Gives information based on scientific studies about medical conditions to which one might be predisposed
  • Gives information in regard to Mendelian disease carrier status
  • Gives information based on scientific studies about individual traits
  • Allows comparisons to other people
  • Customers can download their raw data

Autosomal SNPs in common

  • SNPs in common: 554,618
  • SNPs unique to 23andMe: 23,702
  • SNPs unique to deCODEme: 458,731
  • Conclusion: If you have already done the deCODEme test, then doing the 23andMe test won’t add much new information
