Dear list, I'm trying to find the list of genes with a given go term. I'm using two different methods and I get different results for amigo web page. If I use: > library(GO.db) > library(org.Hs.eg.db) > res <- get("GO:0006913", revmap(org.Hs.egGO)) > res <- do.call('c', mget(res, org.Hs.egSYMBOL)) > sort(unique(res)) [1] "AAAS" "ANKRD54" "ANP32A" "CAMK1" "CDK5" "EIF5A" "MLX" [8] "MLXIP" "MYBBP1A" "NPM1" "NUP155" "NUP205" "NUP98" "RAN" [15] "RBM15B" "RSRC1" "SET" "ZNF384" I get 18 genes. According to amigo, AXIN1, CAMK4, NUP62, UPF3A and UPF3B should be there too. If I use biomaRt I get: > library(biomaRt) > ensembl <- useMart("ensembl", dataset = "hsapiens_gene_ensembl") > res <- getBM(c("hgnc_symbol"), filters = "go", values = "GO:0006913", mart = ensembl) > sort(unique(res[,1])) [1] "AAAS" "ANKRD54" "ANP32A" "AXIN1" "CAMK1" "CAMK4" "CDC42" [8] "CDK5" "DIRAS1" "DIRAS2" "DIRAS3" "DNAJC27" "EFCAB4B" "EIF5A" [15] "HRAS" "IFT27" "KRAS" "LRRK2" "MLX" "MLXIP" "MRAS" [22] "MYBBP1A" "NPM1" "NRAS" "NUP155" "NUP205" "NUP54" "NUP98" [29] "NUPL1" "RAB10" "RAB11A" "RAB11B" "RAB12" "RAB13" "RAB14" [36] "RAB15" "RAB17" "RAB18" "RAB19" "RAB1A" "RAB1B" "RAB20" [43] "RAB21" "RAB22A" "RAB23" "RAB24" "RAB25" "RAB26" "RAB27A" [50] "RAB27B" "RAB28" "RAB2A" "RAB2B" "RAB30" "RAB31" "RAB32" [57] "RAB33A" "RAB33B" "RAB34" "RAB35" "RAB36" "RAB37" "RAB38" [64] "RAB39" "RAB39B" "RAB3A" "RAB3B" "RAB3C" "RAB3D" "RAB40A" [71] "RAB40AL" "RAB40B" "RAB40C" "RAB41" "RAB42P1" "RAB43" "RAB43P1" [78] "RAB44" "RAB4A" "RAB4B" "RAB5A" "RAB5B" "RAB5C" "RAB6A" [85] "RAB6B" "RAB6C" "RAB7A" "RAB7L1" "RAB8A" "RAB8B" "RAB9A" [92] "RAB9B" "RABL2A" "RABL2B" "RAC1" "RAC2" "RAC3" "RALA" [99] "RALB" "RAN" "RAP1A" "RAP1B" "RAP2A" "RAP2B" "RAP2C" [106] "RASD1" "RASD2" "RASEF" "RASL11B" "RASL12" "REM1" "REM2" [113] "RERG" "RHOA" "RHOB" "RHOC" "RHOD" "RHOF" "RHOG" [120] "RHOH" "RHOJ" "RHOQ" "RHOU" "RHOV" "RIT1" "RIT2" [127] "RND2" "RND3" "RRAS" "RRAS2" "RSRC1" "SET" "ZNF384" This is a bigger list. I don't know exactly what's happening here. Can anyone tell me what am I doing wrong?
