The sequencing of the human genome was a remarkable feat, yet using this information to understand human health and disease has proven to be challenging. The mammalian genome is comprised of a complex infrastructure of defined nucleotide sequences and dynamic epigenetic modifications that result in shifts in gene expression patterns and subsequent developmental and phenotypic outcomes. Genome wide association studies (GWAS) have demonstrated the link between alterations in nucleotide sequences created by mutations, such as single nucleotide polymorphisms (SNPs) and disease. However, it remains unclear how SNPs alter gene expression patterns and phenotypes. One hypothesis links SNP containing regions to mutational phenotypes via changes to epigenetic processes that control how genes are regulated, such as DNA methylation and histone acetylation.\u0000\u0000SNPs are changes in nucleotide sequences that occur in at least 1% of the population. It is estimated that there are 10 to 30 million SNPs in humans that occur every 100 to 300 bases, and this variation is the major source of heterogeneity among people. A nonsynonymous SNP changes the amino acid sequence of a protein-coding gene. Less than 10% of SNPs are nonsynonymous, whereas 90% occur in nonprotein coding regions of the genome.1 SNPs can be found in regions of deoxyribonuclease I (DNase I) hypersensitivity or promoters affecting transcription factor–binding sites and chromatin state. SNPs can create or delete microRNA-binding sites in 3′ untranslated regions (UTRs) affecting microRNA target mRNA expression.2 SNPs can also be found in regions expressing noncoding RNAs, such as long noncoding RNAs (lncRNAs) leading to alterations in their expression patterns.

The current difference globally is on average 4 years, and the difference is even larger in populations with longer life expectancy, for example, ≈6 years in the European Union and 7 years in Japan.1 A larger difference in populations with higher longevity suggests that the underlying factors are stronger in populations with a large part of the mortality related to age-associated diseases. Cardiovascular diseases are the leading causes of death globally and are increasing.2 The share of total mortality that is because of cardiovascular diseases is similar in both sexes, but men fall ill and die from it at a younger age.
