Hi all,

I'm sure it's just me missing something obviuos... but I can't find PTEN in TxDb.Hsapiens.UCSC.hg38.knownGene.

If I do this with two genes in hg19 I get the positions for both genes

> library(AnnotationDbi)
> library(TxDb.Hsapiens.UCSC.hg19.knownGene)
> library(TxDb.Hsapiens.UCSC.hg38.knownGene)

> AnnotationDbi::select(org.Hs.eg.db::org.Hs.eg.db, keys=c("NF1", "PTEN"), keytype="SYMBOL", columns="ENTREZID")

> all.genes <- genes(TxDb.Hsapiens.UCSC.hg19.knownGene)
> all.genes[(all.genes$gene_id %in% c("4763", "5728"))]
GRanges object with 2 ranges and 1 metadata column:
       seqnames            ranges strand |     gene_id
          <Rle>         <IRanges>  <Rle> | <character>
  4763    chr17 29421945-29708905      + |        4763
  5728    chr10 89623195-89728532      + |        5728
  -------
  seqinfo: 93 sequences (1 circular) from hg19 genome

However, if I do the same with hg38 I only get the information for NF1 but not for PTEN

> all.genes <- genes(TxDb.Hsapiens.UCSC.hg38.knownGene)
> all.genes[(all.genes$gene_id %in% c("4763", "5728"))]
GRanges object with 1 range and 1 metadata column:
       seqnames            ranges strand |     gene_id
          <Rle>         <IRanges>  <Rle> | <character>
  4763    chr17 31094927-31381887      + |        4763
  -------
  seqinfo: 595 sequences (1 circular) from hg38 genome

Am I missing someting? or PTEN was not included into the TxDb?

Thanks a lot!

I think there was a similar question answered by @kayla.interdonato here.

If you set single.strand.genes.only=FALSE (note it gives a slightly different structure) you will see PTEN

> all.genes <- genes(TxDb.Hsapiens.UCSC.hg38.knownGene, single.strand.genes.only=FALSE)
> all.genes[names(all.genes) %in% c("4763", "5728")]

Thanks Lori!

It works perfectly with that. If I understand correctly, this is due to PTEN mapping onto the canonical chromosome and on a gemome patch, isn't it?

In any case, it seems I'm not the only one wondering where my genes have gone! Maybe a note on the existence of this option could be added to the GenomicFeatures vignette? Thanks again!

Thank you for the suggestion we will look into it.

FWIW: I have submitted a pull request that will output a message when this filtering occurs - hopefully it will be helpful. https://github.com/Bioconductor/GenomicFeatures/pull/20
