Abstract

As of this report, the NIAAA Repository/Natural History Database includes phenotype and/or genomic data on 3277 individuals. Phenotype data include psychiatric diagnoses, a variety of alcohol-related assessments and measures including lifetime and recent consumption and alcohol response phenotypes, personality and impulsivity measures, depression and anxiety symptoms, current and early life stress and trauma, aggression, suicidality, smoking, IQ, sleep quality, pain, and overall quality of life. Laboratory/biochemical measures are also available. Genomic data include 1) large-scale single nucleotide polymorphism (SNP) genotyping performed using Illumina arrays, 2) exome sequencing of a subset of subjects, both via a partnership between the Clinical Core Laboratory of the OCD, and the Laboratory of Neurogenetics (NIAAA), and 3) DNA methylation data for a subset of subjects via a partnership with the Laboratory of Neurogenetics. All NIAAA PIs and their research staff are encouraged to submit data requests in order to conduct research projects and analyses using the shared NIAAA Repository/Natural History Database. Projects are logged and the status is tracked from initial request to manuscript publication. In addition, Human and Genomic data are shared via BTRIS and other mechanisms, including collaboration with NIH-supported consortia (PGC Alcoholism, ENIGMA) to ensure data sharing. I.

Projects (3) resulting in manuscript submissions, revisions, or publications in press, within the past year: Association between FXYD2 and DRD2 genes and measures related to dopamine signaling in alcohol use disorder The role of C-Reactive protein in alcohol use disorder Role of current stress and perceived stress in alcohol-dependence severity and quality of life: an update to the study of childhood trauma in alcohol use disorder Quality of life among patients with alcohol use disorder and healthy controls: Examining the effects of genetics, childhood adversities, drinking histories, and lifetime suicidality III. Projects (6) with manuscripts in preparation: Latent profile analysis of impulsive and compulsive drinking Reporting of adverse childhood events as a function of race/ethnicity and gender and their influence on drinking behaviors Electrocardiogram and other cardiovascular indicators of at-risk alcohol drinking An investigation into the role of metabolic biomarkers in the anticipation of reward in treatment seeking alcoholics (second manuscript from this project) Immunoglobulin levels in alcohol use disorder and their association with comorbid major depressive disorder and chronic stress Association between dopaminergic genetic variation and IV alcohol consumption in the lab and in the field.

Data analyses are ongoing. Differences in hypothalamic-pituitary-adrenal axis responses to alcohol withdrawal-induced stress in black and white individuals with and without alcohol use disorder. Data analyses are ingoing. Interactions between the UPPS-P impulsivity facets and alcohol related outcomes. Data analyses are ongoing. The impact of trauma timing and load on brain-behavioral measures of Alcohol Use Disorder. Data analyses are ongoing. V. New projects (2) initiated within the past year: Differences between those with only AUD and those with AUD and depression with an emphasis on the ANA framework Association of early life and current stressors with alcohol use and BMI VI. Other Progress As a result of an established collaboration with Indiana University (Tatiana Foroud and Arpana Argawal), a manuscript was published including data from the NIAAA Repository/Screening Database, looking at admixture mapping of DSM-IV alcohol dependence, criterion count, and the self-rating of the effects of ethanol in African American populations. The collaboration with The Alcoholic Hepatitis Network project (AlcHepNet) is ongoing and data were shared with the group to be used in investigations of genetic variation and new treatments in alcoholic hepatitis.
