The SNPs in the human genetic blueprint era

The analysis of human genetic variability can lead to the comprehension of medical issues and to the development of personalized therapeutic protocols. Single nucleotide polymorphisms, are the most common type of human genetic variation and have been associated to disease development and phenotype forecasting. The recent technologies for DNA sequencing and bioinformatic analysis are now giving the opportunity to develop new diagnostic and prevention approaches also through health promotion protocols. The genetic data management is at the same time underlining technical limitations and old ethical issues
