Family Finder versus deCODEme

Jump to: navigation, search

This page on Family Finder versus deCODEme seeks to compare the Family Finder autosomal DNA test from Family Tree DNA with the autosomal DNA test from deCODE genetics.

Uses Affymetrix’ Axiom CEU SNP chip
Tests 563,800 autosomal DNA SNPs
Tests no Y chromosome SNPs
Tests 15,789 X chromosome SNPs
X chromosome browser in beta-testing
Tests no mtDNA SNPs
Ancestral origins feature in development based on ancestry-informative markers from many reference populations worldwide
Gives no information about medical conditions one might be predisposed to since the 3,296 medically relevant SNPs have been removed
Allows comparisons to other people similar to Relative Finder
Customers can download their raw data

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 mitochondrial DNA 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

Comparing autosomal SNPs

SNPs in common: 209,099
SNPs unique to deCODE: 804,250
SNPs unique to Family Finder: 354,701
Conclusion: A little more overlap than with 23andMe, but still many unique SNPs in each test
