Remarkably, two variants located in DNAJC13 (p.Leu583Ser and p.Arg1588His), two variants located in GIGYF2 (p.Glu811Ala and p.Pro1155Thr), and one variant located in HTRA2 (p.Thr215Met) were present in 3.1% (6/191) of the PD individuals but absent in the controls. The gene discussed is HTRA2; the disease is Parkinson disease.
