biostudies-literatureUnknown115(6)Morton NEThe causal chain between a gene and its effect on disease susceptibility cannot be understood until the effect has been localized in the DNA sequence. Recently, polymorphisms incorporated in the HapMap Project have made linkage disequilibrium (LD) the most powerful tool for localization. The genetics of LD, the maps and databases that it provides, and their use for association mapping, as well as alternative methods for gene localization, are briefly described.The Journal of clinical investigation1425-30https://www.ebi.ac.uk/biostudies/studies/S-EPMC1137007biostudies-literatureLinkage disequilibrium maps and association mapping.PMC1137007Morton NEfalseLinkage disequilibrium maps and association mapping.The causal chain between a gene and its effect on disease susceptibility cannot be understood until the effect has been localized in the DNA sequence.
