The workshop data were examined using a newly developed methodology (MIL-INK, Risch, 1984) for combined segregation, linkage, and association analysis of a complex disease trait in pedigree data. Results from problems two and three suggest that the method is powerful both for determining mode of dis

โฆ Synopsis
Data simulated for Genetic Analysis Workshop I1 were analyzed using PAP. Segregation analysis showed a simple recessive mode of inheritance for data set 2 while no conclusions could be made about the mode of inheritance for data set 3 .
Pairwise linkage analysis suggested three linkage groups, but three-locus analysis did not provide strong evidence for the gene order within these groups. For three of the four three-locus comparisons performed, three-locus analysis suggested the simulated order. In only one case did the pairwise analysis suggest the simulated order, indicating the necessity for multi-locus analysis for gene order.

Familial segregation and linkage analyses were performed on two sets of the Genetic Analyses Workshop II data. The salient features of the mode of inheritance of the disease trait and its linkage/association with polymorphic markers and also marker-marker linkages were delineated using statistical-g
