GWAS
Modifiers
- Objective: homogeneity vs acceleration?
- Flow of analysis using AMP-PD database
- Correlation between GBA and PD progression (by Aug7 2020), if positive →
- Correlation between Lysosomal genes and PD progression
- Interaction between GBA and Lysosomal genes (in one month)
- Cf) can we quantify the contribution of genes to PD progression?
- AUC, PGS, PREDICTIVE Model?
- Preclinical studies
- Validation
- ↑ PD risk,
- Do we need this?
- 공존시 ↑ PD phenotype
- Do we need this? Already clinically proven?
- GBA Tx → ↓ lysosomal alteration → ↓ aSyn
- Do we need this?
- ↑ PD risk,
- Validation
- genes of interest include
- Lysosomal genes of interest include
- All LSD genes (54 genes)
- 5 LSD genes that is known increase PD risk (Robak et al., 2017, doi: 10.1093/brain/awx285): SMPD1, CTSD, SLC17A5, ASAH1, GBA
- non-LSD genes
- TMEM175
- This gene is not an LSD gene but is known to increase PD risk and reduces PD age of onset (by ~0.6 year), {Blauwendraat, 2019 #794}, reduces cathepsin B expression
- CTSB
- CTSB is not a LSD gene but is known to increase PD risk and interacts with GBA to further increase PD risk (Blauwendraat et al., 2019, doi: 10.1101/738351)
- TMEM175
- All LSD genes (54 genes)
- Non-Lysosomal genes of interest include
- SNCA
- increase PD risk and interacts with GBA to further increase PD risk (Blauwendraat et al., 2019, doi: 10.1101/738351)
- SNCA
- Lysosomal genes of interest include

| (Tan, 2022 #2084) GWAS for progression of motor and cognition, and mortality |
We studied 11 cohorts, 6,766 PD patients, over 15,340 visits with a mean follow-up of between 4.2 and 15.7 years and carried out a genome wide survival study for time to motor progression, defined by , cognitive impairment as defined by , and death (mortality).

| (Iwaki, 2021 #1521) GWAS for progression of motor and cognition |
We analyzed 3 large longitudinal cohorts: Tracking Parkinson's, Oxford Discovery, and PPMI. We included clinical data for 3364 patients with 12,144 observations (mean follow-up 4.2 years). → we did not find any overlap between the variants associated with i) PD risk, ii) AAO, & iii) progression. (ie There is minimal overlap in the genetic architecture of PD risk and PD progression.) Similarly, the AAO GWAS showed only a partial overlap with the genetics of PD risk.21
