Among advances in the field of genomic, single-nucleotide polymorphism (SNP) research has attracted a lot of attentions in recent years. SNP genotyping serves as the technological basis to understand the causes of diseases at the genetic level, and is very useful for pharmacogenomic researchers. In order to establish a certain path to the realization of personalized medicine, Riken Genesis is using state-of-the-art technology to explore a total of 6 billion base pairs.
