Survival quantitative trait locus fine mapping by measuring and testing for Hardy-Weinberg and linkage disequilibrium.
I show that fine-scale localization of a survival-related locus can be accomplished on the basis of deviations from Hardy-Weinberg equilibrium and linkage disequilibrium at closely linked marker loci. The method is based on chi(2)-tests and they can be performed for age-specific samples of alive (or dead) individuals, as for combined samples of alive and dead individuals.
متن کاملLee Responds to “Testing for Hardy-Weinberg Disequilibrium”
I appreciate Weinberg and Morris’ thoughtful commentary (1) on my paper (2). In their article, they put my work under the perspective of gene mapping in the postgenomic era. I share the same view with them that the method proposed in my paper amounts to a tree-shaking approach to harvesting the high-hanging fruit (a low-cost approach to generating hypotheses aimed at localizing diseasesusceptib...
متن کاملHardy Weinberg Equilibrium Testing and Interpretation: Focus on infection
Hardy-Weinberg equilibrium (HWE) holds when, in a closed population with random mating and without mutation and natural selection, genotype frequencies at any locus is a simple function of allele frequencies. Testing for HWE is now a common practice in population genetics and genetic association studies of non-communicable diseases; however, it is less-regarded, or sometimes miss-interpreted, i...
متن کاملA Bayesian characterization of Hardy-Weinberg disequilibrium.
A Bayesian method for determining if there are large departures from independence between pairs of alleles at a locus, Hardy-Weinberg equilibrium (HWE), is presented. We endorse the view that a population will never be exactly in HWE and that there will be occasions when there is a need for an alternative to the usual hypothesis-testing setting. Bayesian methods provide such an alternative, and...
متن کاملDetecting marker-disease association by testing for Hardy-Weinberg disequilibrium at a marker locus.
We review and extend a recent suggestion that fine-scale localization of a disease-susceptibility locus for a complex disease be done on the basis of deviations from Hardy-Weinberg equilibrium among affected individuals. This deviation is driven by linkage disequilibrium between disease and marker loci in the whole population and requires a heterogeneous genetic basis for the disease. A finding...
