A workshop was held at Rockefeller University entitled "Phenotypes and Gene
tic Analysis of Complex Traits." The purpose of the workshop was to examine
phenotype definition for complex traits, in particular, psychiatric and ne
uropsychiatric traits. An additional goal of the workshop was to examine st
atistical genetic approaches that specifically address the oligogenic natur
e of psychiatric traits. An overview of topics that were addressed and disc
ussed at the workshop is presented in this article. Am, J. Med. Genet, (Neu
