Figure 2.
Coverage of the CpG-SNP in those probes where the CpG-SNP is genotyped on the array, and those where it is imputed. The coverage of the CpG-SNP was higher in the probes where the CpG-SNP was genotyped. This result was replicated in an independent dataset imputed using the HRC reference panel (Systems Genomics of Parkinson’s Disease Cohort). When the CpG-SNP is imputed, there is a large difference in the coverage between datasets imputed using the 1000 Genomes Project Phase 3 reference panel (LBC-1KG), and those imputed using the HRC reference panel (LBC-HRC, Replication-HRC).
