As of this report, the NIAAA Repository/Screening Database includes phenotype and/or genomic data on more than 2700 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, and 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). All NIAAA PIs are encouraged to submit data requests in order to conduct research projects and analyses using the shared NIAAA Repository/Screening 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.

New projects (7) initiated within the past year: Impaired Control, Suggestibility and Alcohol-Related Outcomes An Investigation into the Role of Metabolic Biomarkers in the Anticipation of Reward in Treatment Seeking Alcoholics Connor-Davidson Resilience Scale (CDRS): association with childhood trauma, alcohol-related outcomes and psychopathology Phenotypic differences in reward, pain, and negative affect measures in individuals with genetic variation in expression of OPRM1 VI. Other Progress As a result of the collaboration established last year with the Psychiatric Genetics Consortium (PGC), a manuscript was published including data from the NIAAA Repository/Screening Database, looking at genome-wide associations with alcohol use disorder. In collaboration with Indiana University and the Centenary Institute in Australia, a manuscript was published including data from the NIAAA Repository/Screening Database, looking at genetics of the self-rating effects of alcohol. A new collaboration is being established with The Alcoholic Hepatitis Network project (AlcHepNet) to share data relevant to investigations of new treatments in alcoholic hepatitis.
