RT-PCR analysis of genes within 2 Mb of JA04. The results of the qualitative PCR for the 19 genes identified in this region. RNA from 20 tissues was used along with a blank control (lane 16) for the RT-PCR step. The genes are listed on the left along side their corresponding gel. The number of ESTs identified in brain libraries is listed on the right along with the total number of ESTs for that gene.
