Multipoint linkage analysis of XmnI-Gγ adjusted and unadjusted FC traits across 56 cM of chromosome 8q. Single-point lod scores from the original study are shown with bars above the markers tested. Because of missing genotype data, 315 of the 319 total twin pairs were used in the multipoint analysis. ^*Markers were used in the original linkage study in the Asian Indian kindred but not in the multipoint analysis.
