TMEM230 and Parkinson disease: We did not identify any pathogenic mutations in the coding region of TMEM230 gene in the PD patients and controls, while we identified three known (c.68 + 182G > A, c.78A > G, c.552 + 11A > G) and one unknown SNPs (c.174 + 11C > T) both in the patients and controls (Table 1).
