The patient also underwent an NGS analysis focused on Parkinson’s disease (including the following genes: ATP13A2, DNAJC13, DNAJC6, EIF4G1, FBX07, GBA, GCH1, GYGYF2, GRN, HTRA2, LRRK2, MAPT, PARK2, PARK7, PINK1, PLA2G6, SNCA, VPS35, SYNJ1, UCHL1, TMEM230, RAB29B); neither pathogenetic/probably pathogenetic nor unknown significance variants were identified. Here, GCH1 is linked to Parkinson disease.
