We compared our gene set with the gene set presented in the study by Infante and colleagues, and revealed overlap genes, encoding monocyte-attracting chemokines, such as CCL3L1 gene, when comparing GBA-PD, G2019S LRRK2-PD, and PD to controls, and the CCL3 gene, when comparing GBA-PD to controls and G2019 LRRK2-PD to G2019S LRRK2-carriers. The gene discussed is LRRK2; the disease is Parkinson disease.
