Currently, the technology known as Next Generation Sequencing (NGS), is considered us to study our DNA from different strategies,diagnosis of human genetic diseases.It is worth it to highlight that since the development of the human genome project (Figure 1), in 20011,2 the cost of sequencing a genome has decreased from 100 million dollars, to about 1000 euros today, in terms of reagent costs.
Sequencing cost decreasement, computing capabilities increment and the unstoppable advance of scientific knowledge, have allowed the identification of hundreds of new genes associated with diseases, identifying biomarkers of risk of susceptibility to diseases or possible adverse effects to medications..
The benefits of Next Generation Sequencing (NGS)
NGS allows us to study our DNA from different strategies, from the least complex, in which we can study a panel of genes of interest,followed by the sequencing of the entire coding region of the genome6 (that which is formed by genes that encode all the proteins of our organism) known as WES, until the most complex, the complete sequencing of the 3,000 x 10^6 base pairs that make up our entire genome (Figure 2).

As a result of this technology development, the diagnostic performance has increased considerably in many diseases, such as intellectual disability, cardiovascular diseases, cancer, thanks to the identification of new genes, genomic regions and associated biomarkers. The recent challenge has been to translate all these findings and technological developments into clinical routine, in such a way that anyone can have access to genetic diagnostic tools, whenever they need them.
