## Abstract Methods of varying complexity have been proposed to efficiently estimate haplotype relative risks in caseβcontrol data. Our goal was to compare methods that estimate associations between disease conditions and common haplotypes in large caseβcontrol studies such that haplotype imputatio

β¦ Synopsis
In the haplotype relative risk (HRR) statistic (Rubinstein et al.: Human Immunol 3:384 [abstract], 1981), a disease sample is constructed along with its own internal control by comparing those marker alleles passed from the parents to an affected child with the other parental marker alleles not transmitted. Based on the conditional parental genotype distribution given that they have an affected child, statistical properties of the HRR statistic are derived. It is shown that the HRR is different from 1 only when allelic association is present and the recombination fraction is different from %. Transmitted and nontransmitted marker alleles are shown to be statistically independent only in the absence of either allelic association or recombination.

Two tests for allelic association were applied to a simulated complex disease for the Genetic Analysis Workshop 9. The transmission/disequilibrium test [Spielman et al., 19931 and the haplotype-based haplotype relative risk approach [Terwilliger and Ott, 19921 were used to detect disease-associated
Intended to resolve the problem of constructing a matched population-based control sample, haplotype relative risk techniques frequently suffer from loss of power for late-onset diseases due to unavailability of parental genotypes that are required to form parent-offspring pairs. However, much of th
