Table 2 Test statistic results by functional class within 9 annotation schema. Amongst 9 schema, a total of 127 functional classes ("Classes") contained expressed genes ("Total Genes"), and of these, 102 classes had a sufficient number of expressed genes (>50, "Class>50") to enumerate ("Genes F>3.51") and calculate fractional representation ("%>3.51", also Figure 3) in the nominal p = 0.05 tail at a test statistic cutoff of 3.51. 7853 genes with expression in at least one tissue >LN(100) were included.
