We detected 12 different novel and known pathogenic PD variants in PINK1 (p.Y253D, p.A340P, and p.N521T), PARK2 (p.S167N and p.V380L), and LRRK2 (p.R50H, p.N551K, p.R1398Q, p.S1647T, p.R1628P, p.N2081D, and p.M2397T) in eight different carriers, all of whom were heterozygous for the variant. This evidence concerns the gene LRRK2 and Parkinson disease.
