Figure 5. The Pearson correlation between Robo2 and Ncam2. Ncam2 was the second highest correlate to Robo2 in the Department of Defense (DoD) Congressionally Directed Medical Research Programs (CDMRP) Normal Retina Database. These data indicate that these two genes are co-regulated with across the BXD strain set. When one gene is high in a strain the other gene is also expressed at a high level.
