| App has a suggestive QTL
   on Chr 2. What about the neighbors that we defined as having shared
   expression patterns. This figure shows that members of the immediate App
   neigborhood share a weak Chr 2 QTL. 
   That is what the blue oval in the background is meant to represent.
   But some transcripts, such as Ndr4 and Psen2 do not share this Chr 2
   interval. | |
| QUESTION: What kind of
   headway can we make in detemining what polymorphism or polymorphisms on Chr
   2 near 130 Mb might contribute to the variance in the expression of all of
   these important transcripts? |
