Family genetics of alcohol use disorder

Official title: Collaborative Study on the Genetics of Alcoholism (COGA).

Funded at Suny Downstate Medical Center · NIH-11195688 · Data updated 2026-11-12

This project looks at how genes, brain function, and life circumstances shape alcohol problems, recovery, and relapse in people from large families, with a new focus on those aged 40 and older.

Who could benefit from this research

Could help

Ideal candidates are adults from families with a history of alcohol use disorder—especially people aged 40 and older—and their relatives who can provide health information and biological samples.

Less likely to help

People without a family history of alcohol problems or those unwilling to complete interviews, testing, or provide biospecimens are less likely to receive direct benefit from participation.

What this research studies

You and your family members can take part in regular health interviews, questionnaires, cognitive tests, and brain measurements, and may be asked to provide blood or saliva samples. Researchers combine those clinical and neurophysiological measures with genomewide and molecular data to find genetic and biological factors that change risk or resilience for alcohol use disorder (AUD). COGA follows large, diverse families many of whom have multiple affected members, and it is adding targeted follow-up for participants as they enter later life (40+). Participation typically involves multi-domain visits over time so researchers can track remission, recurrence, and alcohol-related health outcomes across the lifespan.

Why it matters

Potential benefit: If successful, this work could help identify people at higher or lower risk and inform better prevention and personalized treatment approaches for alcohol use disorder.

How similar studies have gone: Earlier genetic and family-based studies, including prior COGA publications, have identified risk genes and brain markers, but this long-term, multi-domain follow-up focused on older adults is relatively unique.
