  • The genetics of alcohol dependence: Twin and SNP-based heritability, and genome-wide association study based on AUDIT scores. - American journal of medical genetics.

    Alcohol dependence (AD) is among the most common and costly public health problems contributing to morbidity and mortality throughout the world. In this study, we investigate the genetic basis of AD in a Dutch population using data from the Netherlands Twin Register (NTR) and the Netherlands Study of Depression and Anxiety (NESDA). The presence of AD was ascertained via the Alcohol Use Disorders Identification Test (AUDIT) applying cut-offs with good specificity and sensitivity in identifying those at risk for AD. Twin-based heritability of AD-AUDIT was estimated using structural equation modeling of data in 7,694 MZ and DZ twin pairs. Variance in AD-AUDIT explained by all SNPs was estimated with genome-wide complex trait analysis (GCTA). A genome-wide association study (GWAS) was performe

Lifestyle context

Concrete actions anchored to the cited research. We do not prescribe, we describe.

Discuss with your doctor

  • Alcohol dependence risk and family history Moderate

    CNTN5 genetic association with alcohol dependence warrants clinical assessment of risk and preventive strategies

    Inform clinician of this variant; review family history of substance use disorders

Lifestyle

  • Alcohol moderation or abstinence Moderate

    Genetic association with alcohol dependence suggests heightened vulnerability to problematic drinking

    If drinking: women limit to less than 7 drinks per week, men less than 14; abstinence is safest

Screening

  • Alcohol consumption patterns Moderate

    CNTN5 variant associated with increased alcohol dependence risk; monitoring enables early detection of problematic use

    Track frequency and quantity; consider AUDIT-C screening annually
