Approximately 5–10% of patients, however, develop a “monogenic form of Parkinson’s Disease”, which is caused by pathogenic variants in SNCA, LRRK2, and VPS35, genes exhibiting autosomal dominant inheritance, along with PRKN, PINK1, and DJ-1, genes which follow autosomal recessive inheritance [7]. The gene discussed is PRKN; the disease is Parkinson disease.
