From: Impact of pre- and post-variant filtration strategies on imputation

Correlation between the MAF imputed-only markers (non genotyped) with and without QC pre-filtration (44 unreliable structural variants included 12 monomorphic variants reported in dbSNP B137; 29 absent from dbSNP B137 and 3 with discordant alleles compared to NCBI).
