This study identifies stable associations between adult personality polygenic indices and childhood behaviors in the ABCD Study, showing early evidence of genetic influence on traits like mental health and impulsivity.

The paper examines how prenatal social disadvantage and psychosocial stress affect DNA methylation in children and their potential role in psychopathology.

This study identifies 77 genetic loci associated with suicidality through genome-wide association analyses across multiple cohorts and provides biological insights into its genetic architecture.

This paper identifies childhood phenotypes associated with genetic risk for elevated CRP using a PheWAS in the ABCD Study, finding associations with weight, eating, and screen time that are largely independent of BMI.

The paper examines how changes in cognition and neural metrics over time relate to persistent distressing psychotic-like experiences in adolescents, finding that environmental risks are partially explained by these changes.

This study identifies genetic correlations between substance use and aging indices, finding causal effects of tobacco and alcohol use on aging with alcohol effects dependent on quantity.

This study investigates associations between COVID-19 and neuroinflammation markers using DBSI in UK Biobank data, finding increased vasogenic edema in specific brain regions.

The paper shows that multi-omics integration fails to find true-positive novel genes from underpowered GWAS of brain-related traits, highlighting the need for larger sample sizes.

This study shows that childhood socioeconomic status and polygenic scores for cognition independently affect cognitive performance in children, with no interaction between the two factors.

The paper identifies smaller brain volumes in the right dorsolateral prefrontal cortex and insula as predispositional risk factors for alcohol use, supported by genetic and longitudinal evidence.

The paper investigates the genetic link between schizophrenia and substance use disorder, finding shared polygenic liability across multiple datasets.
