The potential genetic link to Parkinson’s disease has garnered significant attention in recent years.

Q: What is Parkinson’s disease?

Parkinson’s disease is a progressive neurological disorder that primarily affects movement control. It results from the degeneration of dopamine-producing neurons in the brain.

Q: Is there a genetic link to Parkinson’s disease?

Yes, studies have shown that genetics can play a role in the development of Parkinson’s disease. While most cases are sporadic, around 15-20% of patients have a family history of the disease, indicating a hereditary component.

Key Genes Associated with Parkinson’s Disease

• SNCA: This gene encodes the alpha-synuclein protein, which is implicated in the formation of Lewy bodies, a hallmark of Parkinson’s disease.
• LRRK2: Mutations in this gene are among the most common genetic causes of familial and sporadic Parkinson’s disease.
• PRKN: The PARK2 gene is linked to early-onset Parkinson’s and plays a role in protein degradation and cellular homeostasis.
• PINK1: Associated with mitochondrial function, mutations in this gene can lead to familial Parkinson’s disease.
• GBA: Mutations in the GBA gene are linked to Gaucher disease and increase the risk of developing Parkinson’s disease.
