Abstract

The broader autism phenotype (BAP) has been conceptualized as a constellation of subclinical traits that parallel the deficits observed in individuals with autism spectrum disorder (ASD). The BAP is thought to represent an intermediate phenotype that is more frequently observed in family members of individuals with ASD. This chapter discusses methodological issues in the assessment of the BAP and describes the domains thought to characterize the BAP in family members and in the general population. It also provides a brief discussion of the etiological significance of the BAP.
