Ratio of ΔGT/GTGT sequence in patients with CD and UC and 3 parents of CGD patients.

Three ratio populations were apparent, approximating to 2:1, 1:1, and 1:2. There was a significant excess of the 1:1 ratio in CD (P < .05), implying an excess of the type II ψNCF1 pseudogene. Each point represents the mean of triplicate measurements.
