I was looking into Ensembl gene name to HGNC gene symbol mapping and, a snapshot of it looks like this,
ENSG00000256024.1 CT476828.6 ENSG00000256252.1 CT476828.7 ENSG00000255638.1 CT476828.4 ENSG00000256521.1 CT476828.11 ENSG00000256490.1 CT476828.10 ENSG00000238720.1 CT476828.2 ENSG00000148828.5 CT476828.1
Now from http://www.gencodegenes.org/gencodeformat.html I understood the Ensembl gene ids has the version number appended with them, but I wonder what are the dot appended values for the hgnc names? Are they unique? If I remove the dots, then many Ensembl names would be mapped to same HGNC gene symbol. Can anyone explain the naming protocol?
