Identification of 64 new risk loci for major depression, refinement of the genetic architecture and risk prediction of recurrence and comorbidities

This study identifies 64 new risk loci for major depression, refines its genetic architecture, and shows strong genetic overlap with other psychiatric disorders and educational attainment.

Cross-trait assortative mating is widespread and inflates genetic correlation estimates

This paper shows that cross-trait assortative mating explains genetic correlations between traits, suggesting many reported genetic similarities may be overestimated.

Accounting for age-of-onset and family history improves power in genome-wide association studies

This paper introduces LT-FH++, a method that improves GWAS power by incorporating age-of-onset and family history, showing increased significant associations in psychiatric disorders and mortality data.

Estimating narrow-sense heritability from genome-wide data in admixed populations

This study estimates narrow-sense heritability in admixed populations using simulations and proposes a PCA-based adjustment to improve accuracy.

Population structure of modern-day Italians reveals patterns of ancient and archaic ancestries in Southern Europe

The paper analyzes the genetic structure of modern-day Italians to reveal ancient and archaic ancestries shaping Southern European populations and Neanderthal DNA distribution.

Genetic analysis of Sephardic ancestry in the Iberian Peninsula

The paper analyzes genome-wide SNP data to assess Sephardic ancestry in Iberian Peninsula populations and surrounding regions, finding evidence of recent Sephardic admixture and challenges in ancestry assignment.
