The genetic architecture of fibromyalgia across 2.5 million individuals

This study identifies 26 risk loci for fibromyalgia through a genome-wide association analysis of 2.5 million individuals, revealing genetic links to neural functions and chronic pain disorders.

Robust inference and widespread genetic correlates from a large-scale genetic association study of human personality

This study identifies 1,257 genetic variants associated with human personality traits using large-scale GWAS and finds widespread genetic correlations with behaviors and life outcomes.

Genome-wide analysis of 102,084 migraine cases identifies 123 risk loci and subtype-specific risk alleles

This GWAS identifies 123 migraine risk loci, including subtype-specific variants and novel targets, supporting neurovascular mechanisms in migraine.

Using multivariable Mendelian randomization to estimate the causal effect of bone mineral density on osteoarthritis risk, independent of body mass index

This study uses multivariable Mendelian randomization to show that higher bone mineral density causally increases osteoarthritis risk independently of body mass index.

Deep learning based brain age prediction uncovers associated sequence variants

This paper uses deep learning to predict brain age from MRI scans and identifies genetic variants associated with the predicted age difference.

Estimating heritability without environmental bias

This study introduces RDR, a method to estimate heritability while removing environmental bias, and applies it to 54,888 Icelanders to estimate heritability for 14 traits.

The nature of nurture: effects of parental genotypes

The paper shows that non-transmitted parental alleles affect a child's traits through their impact on parents and relatives, termed genetic nurture, with significant effects on educational attainment and other traits.
