Simulating a Coalescent Process with Recombination and Ascertainmentl of mutation, genetic drift, and recombination. The method accounts for the potential effects of investigator sampling bias by allowing for ascertainment of chromosomes according to disease status and of markers according to a pre-specified polymorphism cutoff level. The method was implemented in a

Dynamic Programming Algorithms for Haplotype Block Partitioning and Tag SNP Selection Using Haplotypplotype diversity, separated by short regions of low LD. One of the practical implications of this observation is that only a small number of tag SNPs are needed for mapping genes responsible for human complex diseases, which can significantly reduce genotyping effort without much loss of power.

Parametric Bootstrap for Assessment of Goodness of Fit of Models for Block?Haplotype?Structureds for linkage disequilibrium (LD) mapping. Some steps in that direction have been taken by Daly et al.(2001) who describe a block structure of haplotypes. They outline a hidden Markov model (HMM) that allows for common haplotypes in each block. We propose somewhat different models that also use HMM

A Coalescent-Based Approach for Complex Disease Mappingard approach uses family-based ”linkage” methods to identify regions of the genome that harbor susceptibility genes, and then population-based ”linkage-disequilibrium” (LD) methods to search more narrowly for the culprit genes. Many of the important statistical issues involved in the first phase of

How Does Choice of Polymorphism Influence Estimation of LD and Mapping?-off between information and economics. For example, for many of the genetic analytic approaches commonly used in fine-mapping and positional cloning, there is little value in typing polymorphisms that are in near-perfect linkage disequilibrium (LD) with each other. Consequently, investigators may f
