We should consider that elevated serum levels of Gal3 from PD patients have been found (Yazar et al., 2019); (Cengiz et al., 2019) and Gal3 has been identified in the outer layers of Lewy Bodies from PD patients (Flavin et al., 2017), a clear indication that Gal3 may play a yet unidentified role if PD etiology and/or progression. The gene discussed is LGALS3; the disease is Parkinson disease.
