How a dystonia-linked protein affects brain support cells and myelin
Official title: Role of DYT6 Dystonia Protein THAP1 in Oligodendroglial Mediated ECM Homeostasis During CNS Development
Funded at Case Western Reserve University · NIH-11418173 · Data updated 2026-11-12
This project looks at how the THAP1 protein linked to DYT6 dystonia changes the behavior of brain support cells and the surrounding matrix, which could affect myelination in adults with DYT-THAP1.

Who could benefit from this research
✓Could help
Adults diagnosed with DYT-THAP1 (DYT6) dystonia or people with known THAP1 gene variants are the most directly relevant candidates for related future studies or sample donation.
✕Less likely to help
People with movement disorders not linked to THAP1 or those seeking immediate clinical treatments are unlikely to benefit directly from this basic science-focused grant.
What this research studies
Researchers are studying how THAP1 and its partner YY1 control the molecules secreted by oligodendrocyte precursor cells and the makeup of the brain's extracellular matrix. They use lab methods such as ChIP-seq and transcriptomics alongside cell and animal models to see how changes in THAP1 alter chondroitin sulfate molecules that can block myelin formation. The team follows how these molecular changes affect OPC maturation into myelinating oligodendrocytes during CNS development. The goal is to map the pathway by which THAP1 regulates extracellular matrix composition and myelination.
Why it matters
Potential benefit: If successful, this work could identify new targets or strategies to protect or restore myelination for people with DYT-THAP1 (DYT6) dystonia.
How similar studies have gone: Previous work linked THAP1 to developmental myelination, but using THAP1 and YY1 to define how oligodendrocyte precursors shape the extracellular matrix is a relatively new approach.
