This chapter begins with a discussion of strategies for defining autism subgroups. It then turns to the relationship between clinical phenotypes and endophenotypes. This is followed by a review of studies on autism subgroups including morphologically defined subgroups, brain-size defined subgroups, brain-malformation defined subgroups, family-history defined subgroups, core autism behavior based subgroups, cognitively and functionally defined subgroups, and neurologically and medically defined subgroups.
