The Human Genome project is gradually finalizing

the last details of the Human DNA sequence. It is only a matter of time before all 23,000 genes and their gene products will have been mapped and characterized. The results of this historic achieve-ment have brought some interesting findings to light. The polymorphic sequence variants (SNP) and copy variants (PCV) in the genome have opened new avenues for analyzing the genome in search of genes involved in complex diseases. The fairly simplistic view we had on the composition and function of genomes has also been altered seri-ously. A whole series of additional mechanisms that regulate the expression of genes have come to light. In recent years it has indeed been shown that the non-coding sequences of the DNA are not the ‘jun
