Genes associated with Parkinson syndrome

Area of Science:

• Neurogenetics
• Molecular Neurology

Background:

• Parkinsonian Syndrome (PS) encompasses Parkinson's disease and related parkinsonism.
• Genetic factors are increasingly recognized as significant contributors to PS etiology.

Purpose of the Study:

• To review and integrate recent genetic findings in Parkinsonian Syndrome.
• To highlight the role of monogenic variants in understanding PS pathogenesis.

Main Methods:

• Literature review of genetic studies in Parkinsonian Syndrome.
• Analysis of gene mutations associated with dominant and recessive forms of PS.

Main Results:

• Identified mutations in alpha-synuclein, LRRK2, parkin, DJ-1, PINK1, and ATP13A2 genes as causes of monogenic PS.
• LRRK2 mutations are a common cause of dominant PS, particularly in specific populations.
• Autosomal recessive parkinsonism is linked to mutations in parkin, DJ-1, PINK1, and ATP13A2.

Conclusions:

• Monogenic PS variants are crucial for dissecting cellular pathways involved in the disease.
• These genetic insights contribute to understanding the molecular pathogenesis of sporadic PS.
• Further research integrating these findings is essential for a comprehensive understanding of PS.
