Local ancestry-aware genome-wide meta-analysis uncovers novel genetic loci for sickle cell disease nephropathy

This paper performs a local ancestry-aware GWAS on SCD cohorts to identify novel genetic loci associated with eGFR, uncovering regions linked to inflammation, ECM integrity, and other pathways relevant to SCD nephropathy.

Mosaic Loss of Y chromosome associates with lung function, emphysema and epigenetic aging

This study investigates the association between mosaic loss of Y chromosome (mLOY) and lung function, emphysema, and epigenetic aging in men across multiple cohorts.

Prediction and Characterization of Genetically Regulated Expression of Target Tissues in Asthma

Global biobank analyses provide lessons for developing polygenic risk scores across diverse cohorts

This study evaluates polygenic risk score methods across diverse biobanks and ancestries, finding that European reference panels often yield better performance, while PRS-CS outperforms P+T for high-heritability traits.

Meta-analysis fine-mapping is often miscalibrated at single-variant resolution

This paper shows that meta-analysis fine-mapping is often miscalibrated due to cohort heterogeneity and introduces a QC method to identify suspicious loci.
