I found one gene of my top interest, FKBP5, is missing in hugene10sttranscriptcluster.db (v.8.7.0), but is present in the older version v8.2.0. The codes are:
>mapped_probes <- mappedkeys(hugene10sttranscriptclusterSYMBOL)
>xx <- as.list(hugene10sttranscriptclusterSYMBOL[mapped_probes])
>mapped_probes <- mappedkeys(hugene10sttranscriptclusterENTREZID)
>xx <- as.list(hugene10sttranscriptclusterENTREZID[mapped_probes])
>mapped_probes <- mappedkeys(hugene10sttranscriptclusterENSEMBL)
>xx <- as.list(hugene10sttranscriptclusterENSEMBL[mapped_probes])
The outputs are all TRUE using v8.2.0 while all FALSE using v8.7.0. I haven't checked from which version it becomes missing. Since FKBP5 is a major protein-coding gene and seems unlikely missing in RefSeq, GenBank, or Entrez Gene. I'm wondering if you have any idea about this? Thanks!
