TL;DR: This study enhances the catalog of multiple sclerosis risk variants and illustrates the value of fine mapping in the resolution of GWAS signals.
Journal ArticleDOI
Inference of population structure using dense haplotype data
TL;DR: A novel inference framework that aims to efficiently capture information on population structure provided by patterns of haplotype similarity and an efficient model-based approach to identify discrete populations using this matrix, which offers advantages over PCA and over existing clustering algorithms in terms of speed, number of separable populations, and sensitivity to subtle population structure.
