TNFRSF1B and diabetes mellitus: The Idd9.2 region was originally defined as the difference between lines 1105 (formally R11) and 1106 (formally R35) (Lyons et al. 2000), a 5.6-Mb region that includes the candidate genes Cd30 (since renamed Tnfrsf8), Tnfr2 (since renamed Tnfrsf1b), and Mtor. In the subsequent diabetes frequency study depicted in Fig. 2c, line 1105 was not significantly more protected than line 1106 (P = 0.20), although line 1105 trended to a slightly lower diabetes frequency at 210 days.
