21. QUESTION
Less than 10 % of human genome with know(?) functions
• Only 1% code for protein
Identify functional elements in the Human genome
• Genetic approach
• Evolutionary approach
• Biochemical approach
AIM
22. GENETIC
Rely on sequence alterations
To establish the biological relevance of a DNA segment
23. GENETIC
Association ~~~~
• Pearson
• Spearman
• Logistic
Genome-Wide Association Studies (GWAS)
NHGRI GWAS Catalog
25. EVOLUTIONARY
Comparative genomics
only 5% of mammalian genomes are under strong evolutionary
constraint across multiple species (e.g., human, mouse, and dog)
Multiple alignment technology
26. BIOCHEMICAL
Detect biochemical activity
Encyclopedia of DNA Elements (ENCODE) Project
50% of nucleotides in the human genome are readily recognizable
as repeat elements.
