[ensembl-dev] Ensembl 110 - zebrafish ID mapping

[Ian Sealy]

Hi,

Can I ask a question about the ID mapping for Ensembl 110, specifically 
for zebrafish.

We've spotted a number of genes where the HGNC name is now being used 
rather than the ZFIN symbol. For example, kdm2ab is now KDM2A. See:

versus:

For another example, both titin paralogues are now called TTN:

rather than ttn.1 and ttn.2:

http://feb2023.archive.ensembl.org/Danio_rerio/Gene/Summary?db=core;g=ENSDARG00000028213

It seems to be a widespread problem. Looking at the gene table, in 
release 109 there were 23,328 genes with ZFIN names and 164 with HGNC 
symbols. But in release 110 there are only 15,924 using ZFIN and 3113 
using HGNC.

Any idea what's gone wrong? Thanks in advance.

Cheers,
Ian
