The numeric GeneGroup IDs should be used as codes. GeneGroup IDs do not begin with &quot;HGNC:&quot; (like the GeneIDs for genes in HGNC Genes), so care must be made to ensure alignment of concepts when viewing an HGNC ID from an older system that may be referring to the GeneID and not a gene group. For example, 588 refers to the HLA gene family, but HGNC:588 identifies the ATG12 gene. To provide clarity for systems that do not distinguish codes from genes and gene families, use &quot;http://www.genenames.org&quot; for genes and &quot;http://www.genenames.org/genegroup&quot; for gene families as code system URIs.&#xD;&#xA;&#xD;&#xA;&quot;For each known human gene we approve a gene name and symbol (short-form abbreviation). All approved symbols are stored in the HGNC database,[www.genenames.org](https://www.genenames.org/tools/search), a curated online repository of HGNC-approved gene nomenclature, gene groups and associated resources including links to genomic, proteomic and phenotypic information. Each symbol is unique and we ensure that each gene is only given one approved gene symbol. It is necessary to provide a unique symbol for each gene so that we and others can talk about them, and this also facilitates electronic data retrieval from publications and databases.&quot;&#xD;&#xA;&#xD;&#xA;For more information on the use of HGNC Genes, see [https://terminology.hl7.org/CodeSystem-v3-hgnc.html](https://terminology.hl7.org/CodeSystem-v3-hgnc.html).&#xD;&#xA;&#xD;&#xA;HGNC is a free database for the public.&#xD;&#xA;&#xD;&#xA;Please see https://www.genenames.org/ for more info."/><copyright value="It is a condition of HGNC funding from NIH and the Welcome Trust that the nomenclature and information provided is freely available to all.
