in the genome. Gene Expression – RNA-Seq and expression arrays identify expression levels or protein coding genes. Small RNA Expression – smRNA-Seq identifies expression of small noncoding RNA, primarily miRNAs. Reference epigenomes for healthy individuals will enable the second goal of the Roadmap Epigenomics Project, which is to examine epigenomic differences that occur in disease states such as Alzheimer's disease.
