| N2081D genotype | Age of CD onset (SD) [N] | Disease location in ileum [N] | 
|---|---|---|
| AA | 26.5 (14.0) [5601] | 80.5% [5311] | 
| GA | 24.6 (13.1) [482] | 86.1% [453] | 
| GG | 20.8 (9.0) [12] | 90.9% [11] |

SD, standard deviation. N, group sample size. ns, not significant. Similar results were found for the N551K variant (in strong linkage disequilibrium with R1398H, r2=0.81). P values were calculated using simple linear regression.
