title: Genomic coordinates of HGNC gene names
body: <p>I want to get coordinates of human genes from my list (consisting of hgnc genes id) using GenomicFeatures and TxDb.Hsapiens.UCSC.hg19.knownGene R packages from Bioconductor.</p>
  
  <pre><code>library(TxDb.Hsapiens.UCSC.hg19.knownGene)
  txdb=(TxDb.Hsapiens.UCSC.hg19.knownGene)
  
  my_genes = c("INO80","NASP","INO80D","SMARCA1")
  
  select(txdb, keys = my_genes,
         columns=c("TXCHROM","TXSTART","TXEND","TXSTRAND"), 
         keytype="GENEID")
  </code></pre>
  
  <p>However, it doesn't' work because txdb doesn't take hgnc identifiers; how can it be solved? I couldn't find any appropriate keytype that will support hgnc and not sure how to match hgnc id I have and GENEID from txdb.</p>
