deCODEme , launched by deCODE genetics in November 2007, was the first web-based service to offer a comprehensive genome scan and an online analysis of an individual’s DNA profile. This DNA profile is obtained by scanning about 1 million Single Nucleotide Polymorphisms (abbreviated as SNPs and pronounced snips) in one’s chromosomes. Genetics, the science of heredity and variation in living organisms has shown that our propensity to develop certain diseases is located in our genes. Other recently launched companies that offer genetic scans include Navigenics and [[23andme].
