There are 10 known mammalian septin genes, some of which produce multiple splice variants. The
current nomenclature for the genes and gene products is very confusing, with several different names
having been given to the same gene product and distinct names given to splice variants of the same
gene. Moreover, some names are based on those of yeast or Drosophila septins that are not the closest
homologues. Therefore, we suggest that the mammalian septin field adopt a common nomenclature
system, based on that adopted by the Mouse Genomic Nomenclature Committee and accepted by the Human Genome Organization Gene Nomenclature Committee. The human and mouse septin genes
will be named SEPT1–SEPT10 and Sept1–Sept10, respectively. Splice variants will be designated by an
underscore followed by a lowercase “v” and a number, e.g., SEPT4_v1
