This study identifies pathogenic and intermediate repeat expansions in Parkinson's disease and parkinsonism across 11 ancestries, highlighting ATXN2's role in PD risk and ancestry-specific patterns.

This study examines somatic instability of the FGF14 GAA·TTC repeat in SCA27B, finding a cerebellar-specific expansion bias and increased instability in cerebellar regions compared to other brain areas.

The paper identifies human-lineage-specific genomic elements, called CNCRs, and shows their enrichment in neurological disease genes and APOE intron-3 retention transcripts in Alzheimer's disease.

This study identifies cell-type-specific expression of dystonia-associated genes and links them to shared genetic and biological mechanisms with psychiatric disorders.

The paper identifies disease-relevant regulatory loci in human basal ganglia using genomic and transcriptomic data from 117 brains, highlighting splicing eQTLs and ASE analyses as sources of cell-specific regulatory information.

Across 37,688 Parkinson's cases, 18,618 proxy-cases and 1.4M controls, 90 risk signals map to 78 loci (37 new); an 1805-variant polygenic score explains 26-36% of heritability.

This study connects Parkinson’s disease heritability to cell-type-specific gene regulation, finding enrichment in lysosomal genes in astrocytic and microglial subtypes rather than specific cell types or brain regions.
