Hello<br>
<br>
I am confused as to why sometimes i can retrieve records from
ensembl via an entrezgene id and other times not.<br>
<br>
Take this entrezgene id: 441521<br>
The entry for this record says it is related to 2 ensembl genes<br>
<dl id="summaryDl">
<dt>===========================================</dt>
<dd>taken from entrezgene record</dd>
<dt>===========================================<br>
</dt>
<dt>See related </dt>
<dd><a href="http://www.ensembl.org/id/ENSG00000228836">Ensembl:ENSG00000228836;</a>
<a href="http://www.ensembl.org/id/ENSG00000242284">Ensembl:ENSG00000242284;</a>

href="http://www.ncbi.nlm.nih.gov/omim/300796">MIM:300796</a></dd>
</dl>
==========================================<br>
<br>
but this code returns nothing<br>
<br>
my @genes = @{$gene_adaptor->fetch_all_by_external_name(441521,
"EntrezGene")};<br>
foreach my $gene (@genes){<br>
print "gene name: ", $gene->stable_id(), "\n";<br>
}<br>
<br>
<br>
the same code for another gene, 280753, with related ensembl records
<br>
<dl id="summaryDl">
<dt>===========================================</dt>
<dd>taken from entrezgene record</dd>
<dt>===========================================<br>

<dd><a href="http://www.ensembl.org/id/ENSBTAG00000016514">Ensembl:ENSBTAG00000016514</a></dd>
</dl>
===========================================<br>
<br>
does return the ensembl gene. I don't know the mappings which
determine the whether i can get a gene from ensembl by its entrez
gene id<br>
<br>
thanks a lot<br>
