Who are the HGNC and what do we do?

• HUGO Committee. • Responsible for approving unique symbols and names for loci, including coding HGNC: , ncRNA genes and pseudogenes. • Maintain http://www.genenames.org Nomenclature of the horse • Collaborate with • CCDS: RefSeq, HAVANA, Ensembl, MGI, UCSC genome • Other databases, e.g. GeneCards, UniProt • Specialist resources, e.g. IMGT, IUPHAR, miRBase, Beth Yates – Scientific Programmer, HGNC, GtRNAdb EMBL-EBI, Hinxton, UK • Specialist advisors, e.g. HORDE (ORs), SLCS • GO Consortium, Variation Society • Transforming genetic medicine initiative • Other ’ nomenclature groups, e.g. MGNC, RGNC, XGNC, ZNC, AGNC, CGNC, FlyBase

https://vertebrate.genenames.org

Other Vertebrate Gene Naming Groups What about Vertebrate Species with no Nomenclature Group? • Currently only six vertebrate models organisms have naming groups: • Unofficial names from • Inconsistencies between resources MGNC RGNC CGNC • Duplication of symbols within resources • Genes names may be incorrect or uninformative XGNC AGNC ZNC

• Homologous genes are named based on HGNC human nomenclature

Vertebrate Committee HCOP – HGNC Comparison of Orthology Predictions tool • Gene Nomenclature Across Species meeting held in Cambridge, UK; in October 2009

• Gene nomenclature should, where possible, reflect homologous relationships across vertebrate species

• Consensus naming, based on human gene nomenclature, should be extended beyond the species with nomenclature groups

• Care must be taken when assigning gene names to incomplete genomes and to avoid humanisation of non-human genomes • Automated naming should initially focus on consensus 1:1 orthologs as identified by at least two comprehensive orthology resources • Complex families will require expert manual curation for cross-species nomenclature

• VGNC is a new initiative extending the role of the HUGO Gene Nomenclature Committee (HGNC) to coordinate gene naming across vertebrates • Data will be distributed to genomic databases and databases • The VGNC website will become a portal for all official vertebrate nomenclature

Mapping Tool Quick Curate Tool

• Quick Curate tool summarises the information we have for a gene and its 1:1 human ortholog • Displays the reason why the human nomenclature was not automatically transferred • Links to Mapping tool which allows you to view Ensembl and NCBI gene models in a single genome browser

Future plans with VGNC gene naming

• Continue work on naming the remaining chimp, cow, dog and horse protein coding genes • VGNC will prioritize species for naming based on • Quality of genome sequence and annotations • Value of the species in terms of research • Level of interest/input from the research community • Potential next species to consider include pig and rhesus macaque • We will also investigate sheep when Ensembl and NCBI gene have both annotated the latest genome assembly • Gene family curation – specific gene families to be curated across multiple species at the same time
