        | o25K-40K different genes in the human genome ď‚§with splicing & post-translational modification the number of functional proteins is likely greater
 oEstimated that up to 10 genes contribute to a multifactorial disease
 ď‚§Typically these are linked to 5-10 gene products in physiological circuits which are targetable
 o~5000-10000 potential drug targets!
