• Within-Person Changes in Daily Ovarian Hormone Levels Influence Genetic Effects on Emotional Eating in Women September 17, 2025
  CONCLUSION: Cyclic, within-person changes in ovarian hormones may contribute to phenotypic changes in dysregulated eating across the menstrual cycle by dynamically regulating expression of underlying genetic risk. Genetic influences may be particularly pronounced under the hormonal conditions characteristic of the mid-luteal phase (i.e., moderate estradiol and progesterone).

• Genome-wide association meta-analysis of childhood ADHD symptoms and diagnosis identifies new loci and potential effector genes September 17, 2025
  We performed a genome-wide association meta-analysis (GWAMA) of 290,134 attention-deficit/hyperactivity disorder (ADHD) symptom measures of 70,953 unique individuals from multiple raters, ages and instruments (ADHD(SYMP)). Next, we meta-analyzed the results with a study of ADHD diagnosis (ADHD(OVERALL)). ADHD(SYMP) returned no genome-wide significant variants. We show that the combined ADHD(OVERALL) GWAMA identified 39 independent loci, of […]

• Evidence for Genetic Nurture Effects on Substance Use September 5, 2025
  Substance use runs in families. Beyond genetic transmission, parental genetics can indirectly influence offspring substance use through the rearing environment, known as "genetic nurture". This study utilized transmitted and non-transmitted polygenic scores to investigate genetic nurture effects on tobacco, alcohol and cannabis use in up to 15,863 adults with at least one genotyped parent from […]

• Longitudinal Associations between Well-Being and Academic Achievement throughout the COVID-19 Pandemic: Testing the Moderating Role of Academic Stress among First-Generation and Continuing College Students September 2, 2025
  First-generation and ethnic-racial minoritized college students experience greater academic disparities, but limited work has focused on intersectional experiences underlying academic achievement in higher education during the COVID-19 pandemic over time. The current longitudinal study examined the associations between various forms of well-being (i.e., emotional, psychological, and social) at T1 (Time 1; acute pandemic) predicting academic […]

• The impact of investing in private clinics and pharmacies on modern contraceptive uptake: an agent-based model of a segmented market September 2, 2025
  CONCLUSIONS: The factors that family planning policies should target to maximize their effect on modern contraceptive prevalence differ for markets characterized by different social contexts. Success of a policy will require policymakers' attention to the relative preferences for low price, short wait time, short travel time, and quality among population subgroups. Our study results suggest […]

• Deep Phenotyping at Scale: Study Protocol for the Korean Mood Disorder Genetic Study-Depression (KOMOGEN-D) August 25, 2025
  A core challenge in the genetic analysis of major depressive disorder (MDD) is how to recruit large numbers of stringently diagnosed cases with sufficient information to explore the interplay between genetic and environmental risk factors and evaluate genetic influences on putative MD subtypes and key clinical features. Currently, most genome-wide association studies of MDD rely […]

• Phenome-wide association study of male and female sex chromosome trisomies in 1.5 million participants of MVP, FinnGen, and UK Biobank August 21, 2025
  Sex chromosome trisomies (SCTs) are the most common whole-chromosome aneuploidy in humans. Yet, our understanding of the prevalence and associated health outcomes is largely driven by observational studies of clinically diagnosed individuals, resulting in a disproportionate focus on 47,XXY and associated hypogonadism. We analyzed microarray intensity data of sex chromosomes for 1.5 million individuals enrolled […]

• Psychiatric disorders converge on common pathways but diverge in cellular context, spatial distribution, and directionality of genetic effects August 12, 2025
  Psychiatric conditions share common genes, but mechanisms that differentiate diagnoses remain unclear. We present a multidimensional framework for functional analysis of rare copy number variants (CNVs) across 6 diagnostic categories, including schizophrenia (SCZ), autism (ASD), bipolar disorder (BD), depression (MDD), PTSD, and ADHD (N = 574,965). Using gene-set burden analysis (GSBA), we tested duplication (DUP) […]

• Genetic risk effects on psychiatric disorders act in sets August 8, 2025
  Genetic studies of psychiatric disorders have typically assumed that all genetic effects contribute additively to disease liability. However, it is likely that psychiatric disorders have unrecognized subtypes, where synergistic sets of risk variants co-occur within certain cases more than expected under additivity. The existence of synergistic sets induces a structured form of statistical interactions called […]

• A Call for Inclusion: Children With Intellectual Disabilities in Trauma Treatment Research August 7, 2025
  CONCLUSIONS: The evidence base for the ISTSS clinical care guidelines of child PTSD treatment is not representative of children with ID. Improved documentation of inclusion/exclusion criteria, reporting of disability as a demographic characteristic, and inclusion of children with ID in PTSD treatment trials are needed to improve representation of children with ID in PTSD research.
