 While the HGNC only assign nomenclature to human genes, by convention vertebrate orthologs of these genes adopt the same nomenclature (e.g., VGNC-assigned orthologs of SLC10A1).For rodents, the case of the symbols differs from other vertebrates by using title case, i.e.Slc1a1 denotes the rodent ortholog of the human SLC1A1 gene.
