Fetal Alcohol Spectrum Disorder (FASD) is a diagnostic term in the Canadian guidelines and an umbrella term in the US guidelines, that describes the broad range of adverse effects that can result from prenatal exposure to alcohol, including deficits across multiple physical, physiological, neurobiological, and behavioral domains. The prevalence of FASD is estimated to be 1.1–5.0%, which is significantly higher than that of other common disorders, including Autism Spectrum Disorder and Down Syndrome. This relatively high prevalence highlights the urgent need for better recognition, diagnosis, and treatment of this disorder. Currently, however, there are numerous challenges in obtaining an accurate and reliable diagnosis of FASD, and many children remain undiagnosed. This dilemma further highlights the need for new screening and diagnostic tools that provide sensitive biomarkers of prenatal alcohol exposure. Identification of at-risk children at a young age will allow these children access to early interventions and services, which can profoundly change the long-term outcomes and quality of life of individuals with FASD and their families. In this Chapter, we discuss the evidence supporting the emerging potential for genetic, epigenetic, transcriptomic, and proteomic approaches to elucidate FASD etiology, and to serve as potential biomarkers or signatures of early-life events, including prenatal alcohol exposure. We provide an overview of FASD and a brief history of the development of diagnostic criteria, review risk and resilience factors that impact the expression of the disorder, discuss genetic and epigenetic factors in FASD, and conclude by relating these findings to the clinical context.
