| We can compare App
   expression inthe forebrain against transcript expression in hematopoietic
   stem cells. Some of these correlations are significant, but it may be
   difficult to discovery of shared genetic (linkage disequilibrium) or
   molecular processes that give rise to these correlation. | |

   stem cell data belong to Gerald de Haan (University of Groningen) and
