The paper by Miyake et al. (<span>2025</span>) in this journal leveraged data from a large Japanese population-based cohort to investigate the joint associations of maternal alcohol use during pregnancy and maternal genotype on offspring development. We provide context for this study, highlight what we think is its critical finding and key questions that still need to be addressed before considering the potentially serious public health implications of this work.</p><p>Maternal alcohol use during pregnancy is associated with many adverse offspring outcomes (e.g., impaired neurodevelopment, facial dysmorphology, birth defects, growth deficiency) (Popova et al., <span>2023</span>). These are broadly captured under the umbrella term fetal alcohol spectrum disorders (FASD), with fetal alcohol syndrome (FAS) at the severe end. However, like many conditions, FAS and FASD likely reflect continua, with their presentation and severity likely influenced by variable alcohol use, for example, timing and dose. FASD is associated with increased mortality (mean life expectancy for FAS individuals is 34 years old) and has severe social and economic consequences (Popova et al., <span>2023</span>). Despite being preventable, FASD affects >1% of the population in 76 countries (Popova et al., <span>2023</span>), with estimated prevalence rates mirroring rates of maternal alcohol use during pregnancy (Popova et al., <span>2017</span>). For example, in East and Southeast Asia, maternal drinking during pregnancy (South Korea [21.4%], Cambodia [15.4%], Vietnam [12.0%], Japan [8.0%] and China [6.5%]) mirrors prevalence of FAS (per 10,000 births: 31.8, 22.8, 17.7, 11.8 and 9.6, respectively) (Popova et al., <span>2017</span>). Importantly, prevalence rates of both FASD and alcohol use during pregnancy are likely under-estimated. Factors which may contribute to under-estimation include challenges in diagnosing FASD, under-reporting of alcohol use (e.g., due to recall error and stigma), and unintentional drinking during pregnancy (due to unawareness of pregnancy early on). The latter is important considering that, across these East and Southeast Asian countries, estimates of women drinking have increased: current drinkers (1%–20% more in 2017 than 1990; using an inclusive definition of “any alcohol use in the past 12 months”) and heavy drinkers (3%–8% more in 2017 than 1990; excluding Japan, in which this decreased) (Manthey et al., <span>2019</span>). Crucially, although FASD is caused by alcohol use during pregnancy, only a proportion of children who experience prenatal alcohol exposure (PAE) develop FASD.

The final GWAS sample included 8386 individuals who reported alcohol consumption (i.e., AUDIT-C score > 0) during the preceding year. We calculated polygenic scores (PGS) for topiramate treatment response in the Yale-Penn sample (<i>n</i> = 10,275) and examined associations with 692 phenotypes using a phenome-wide association study.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>In the cross-ancestry GWAS meta-analysis, 35 loci had suggestive associations, though none reached genome-wide significance. Topiramate response PGS had nominally significant associations with lower rates of alcohol-related liver disease, older age at alcohol use disorder diagnosis, and higher frequency of alcohol use.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Although no loci reached genome-wide significance, the suggestive variants identified in the cross-ancestry meta-analysis are promising candidates for future investigation. Larger studies are needed to identify significant genetic predictors of topiramate response and advance precision medicine strategies for treating AUD.</p>\u0000 </section>\u0000 </div>","PeriodicalId":72145,"journal":{"name":"Alcohol (Hanover, York County, Pa.)","volume":"49 6","pages":"1197-1205"},"PeriodicalIF":3.0,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/acer.70069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144059756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
