Parkinson’s disease (PD) affects nearly 2% of adults over 65, making it the second most common neurodegenerative disorder. It leads to tremors, stiffness, slow movement, and balance issues due to the gradual loss of dopamine-producing neurons in the brain.

Scientists have identified a rare genetic mutation in ITSN1 that increases the risk of Parkinson’s disease by up to tenfold, marking one of the most significant genetic discoveries in the field. This breakthrough,
