A team of scientists has revealed a breakthrough discovery, linking genetic variants in the gene ITSN1 to a significantly elevated risk of Parkinson’s disease, a neurodegenerative condition that affects nearly 2% of adults older than 65 years. The work, led by an international team of researchers at Baylor College of Medicine, AstraZeneca and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, could pave the way for new treatments aimed at slowing or preventing Parkinson’s disease progression.
Parkinson’s disease, the second most common neurodegenerative disorder, still has no cure.
“To tackle this unmet need, we analysed genetic data from nearly 500,000 UK Biobank participants and discovered that individuals carrying rare ITSN1variants that impair the gene’s normal function face up to a tenfold higher risk of developing Parkinson’s disease,” said author Dr Ryan S Dhindsa, assistant professor of pathology and immunology at Baylor College of Medicine.
