✦ Synopsis

Problem 1 was designed to involve an oligogenic model with four "disease susceptibility" loci, such that all individuals with at least four "upper-case" alleles were at equal risk to be affected (and those with three or fewer were not at risk). Two of these loci were identical to marker loci, thus giving rise to weak disease-marker associations. The other two were located between marker loci, with no linkage disequilibrium. Participants were given 200 nuclear families with at least one affected child, along with 100 control families with no affected individuals. The first two loci were intended to be detectable via association analysis. The remaining two loci were virtually undetectable in this data set.

The participants of Presentation Group 1 used the GAW13 data to derive new phenotypes, which were then analyzed for linkage and, in one case, for association to the genetic markers. Since the trait measurements ranged over longer time periods, the participants looked at the time dependence of partic

We analyzed disease-marker associations in Problem 3 for the Genetic Analysis Workshop 11, using PAP for segregation analysis and LIPED for linkage analysis. In this report we present aspects of our analyses that are not reported in the summary [MacCluer et al, 19841. Certain features that we added
