Data file: apob3gh.dat.
Parameter files: apob_ca.par, apob_cj.par, apob_jp.par.
The group columns in both data files tell the ethnic origin of the individuals where 0 = Japanese and 1 = non-Japanese. In the control group, all non-Japanese were Caucasians.
Among the Japanese patients in the orginal data, 16 of them were from the families in the above pedigree data apob3gh.dat. Those people were selected for linkage analysis with above pedigree structures.
A subset of the markers (13) was selected for linkage analysis since many of the markers are very close to each other and not informative for linkage analysis.
