Fig. 2 Multipoint analysis for the 12 markers studied in the first stage (MAPMAKER/SIBS). LOD scores are shown for the overall data set, CD only, and for the different groups according to sex. A multipoint MLS of 2.4 (P = 0.0004) (2.5 in CD subgroup; P = 003) was observed in the pericentromeric region around dXs990 and dXs8096 (peak of linkage).

Fig. 3 Exclusion mapping using the criterion of LOD-2 for a disease locus λs= 2 in the first stage and data set of 79 affected sibling pairs (MAPMAKER/SIBS). Except for the pericentromeric region of the X chromosome, the remainder of X may be excluded as containing a susceptibility gene, of λs≥2.

Fig. 4 Multipoint analysis in stage 2 investigation involving 145 affected relative pairs (GENEHUNTER). The NPL-1 linkage support interval around the peak is shown and spans 19.7 cM. Maximum linkage is seen around dXs1203 (NPL score, 2.90; P = 0.0017).
