Interestingly, PD patient ESB‐01‐10, heterozygous for an alternate LRRK2 variant (L119P), (orange filled circle, Fig. 2C,D) had an IC50 value similar to patients that did not carry the G2019S LRRK2 mutation (shown generally in open green circles, Fig. 2C,D). The gene discussed is LRRK2; the disease is Parkinson disease.
