Figure 12. Model of gene expression. Data in this figure are taken from Table 4. Cryba4 is the most compelling of several candidates on Chr 5. Exp: mean expression level. Positions of genes are abbreviated C3@89Mb=chromosome 3 at 89 Mb. The correlation between expression of transcripts is indicated by the curved arrow (r=0.71). The large vertical arrow between Cryba4 and Lenep mRNAs is a causal hypothesis that requires testing. It is also possible that this arrow originates from one of the other candidate genes.
