A groundbreaking study has uncovered genetic links to specific subcortical regions, shedding light on their roles in learning, memory, motor skills, and emotional regulation.the findings, which delve into the intricate genetic architecture of the brain, reveal that the brainstem showed the highest number of independent genetic associations, while the amygdala had the fewest.
Among the key discoveries, genes such as CRHR1, MAPT, and ZNF786 were associated with brain volumes, supporting their roles in intracellular signaling and brain aging processes, including tau pathology and vascular resistance. These insights were further refined through functional annotation and gene prioritization using tools like MAGMA and transcriptome-wide association studies (TWAS). As an example, the forkhead box O3 (FOXO3) gene was linked to multiple brain structures, highlighting its broader influence on brain morphology.
Genes from the WNT family were also identified,connecting them to brainstem and ventral diencephalon volumes. These findings suggest potential targets for addressing brain disorders tied to structural variations.To bolster these findings, researchers integrated single-cell RNA sequencing data with GWAS results.
