Dear Biomart team,

I used biomart in R/bioconductor to map ensembl gene ids to gene symbols. I found sometimes a single gene id associates with multiple gene symbols, for example ENSG00000167380, which associates with both 'ZNF234' and 'ZNF226'.

By searching 'ZNF234' in Ensembl browser, I got 'ZNF226' (chr19: 44,645,710 - 44,681,836) returned instead which seems that the later took over both. Does this mean gene record in this region has been updated, but not yet in R/Bioconductor? I looked into the UCSC browser as well, where still two separate records for each of the two gene symbols are kept: ZNF234 (chr19: 44,645,710 - 44,664,460), ZNF226 (chr19:44,669,249 - 44,681,836). It would be very much appreciated if you could help to clarify on this. Thank you very much in advance!

Cheers,
Yuan
