Abstract
We present a method to perform fine mapping by placing haplotypes into clusters on the basis of risk. Each cluster has a haplotype “center.” Cluster allocation is defined according to haplotype centers, with each haplotype assigned to the cluster with the “closest” center. The closeness of two haplotypes is determined by a similarity metric that measures the length of the shared segment around the location of a putative functional mutation for the particular cluster. Our method allows for missing marker information but still estimates the risks of complete haplotypes without resorting to a one-marker-at-a-time analysis. The dimensionality issues that can occur i...
