Uncovering the Genetic Roots of Bipolar Disorder through Mosaic Mutations

Researchers have discovered that patients with bipolar disorder (BD) possess mosaic variants enriched in genes related to developmental disorders and autism spectrum disorder. Additionally, significant heteroplasmic mutations in mitochondrial tRNA genes were found in BD participants. The study sheds new light on the genetic architecture of BD and provides more insights into the pathological contribution of mosaic variants in human diseases.
