Abstract
The pervasive effect of genetic variation on medically important
phenotypes provides a means for dissecting their underlying mechanisms
by identifying variants that are associated with traits of interest.
Current trends in human genetics now facilitate, for the first time,
pursuing this potential by execution of large scale studies that scan
the entire genome for potentially associated variants. Specifically, the
talk will present
(1) The International HapMap Project, a data resource we participated in
developing to enable genomewide association studies, and what our
analyses of these data tell us about human variation.
(2) The current generation of SNP array technology, and how computation
and statistics improvements allow it to cover the majority of common
human variants.
(3) The tale of a pilot association scan in an isolated population in
Micronesia, where we show such scans are more promising than elsewhere,
though we expose practical complexities of real data and the
computational challenges they present.
