A hidden gene finally explains this rare neurological disorder
Researchers in Germany have identified a gene mutation in CD99L2 as the cause of a rare neurological disorder known as X-linked spastic ataxia. The study reveals that this gene is essential for neuronal signaling and interacts with the protein CAPN1.
Why it matters
This discovery provides a genetic explanation for previously unsolved movement disorders and opens new avenues for neurodegenerative disease research.
Even with today's advanced DNA sequencing technologies, the underlying genetic causes of many rare movement disorders remain unknown. Researchers in Germany have now uncovered an important new clue. By analyzing 2,811 people with ataxia, hereditary spastic paraplegia, and dystonia, scientists identified harmful variants in a gene called CD99L2 as the cause of X-linked spastic ataxia.
