| Description | A set of associated SNP alleles in a region of a chromosome that tend to be transmitted as a set. Haplotype is a set of genetic changes - usually a group of SNPs that tend to be inherited together. It could be called as a "gene neighborhood." Haplotype information is used to compare the genes of people affected by a disease with the genes of unaffected people. For example, this approach has revealed a genetic variation that substantially increases the risk of age-related macular degeneration, the leading cause of severe vision loss in older people. The information may be helpful in the future for disease screening and for the development of new therapies. |
