When comparing the NIH cohort data with the UPSIT scores of 519 individuals extracted from the PPMI whole exome sequencing meta data, no statistically significant differences between our heterozygous or homozygous GBA1-PD and those with idiopathic PD (n = 340) was found, while the healthy controls (n = 179) differed significantly from our PD groups. The gene discussed is GBA1; the disease is Parkinson disease.
