For mutations in different genes that all have similar phenotypes, a single name followed by consecutive numbers should not be used. This nomenclature makes the field less accessible to the outsider. A mutation in a second gene resulting in cyclopia could be called fused eyes, but should not be called cyclops2. Genes identified by mutation are typically named to reflect the mutant phenotype. Full gene names are lowercase italic, no hyphens.
Gene symbols consist of three lowercase letters.
The letters should be unique with respect to other named zebrafish mutants and genes and, if possible, gene symbols in mammalian species. The symbol should be derived from the full name. For example, the abbreviated name for cyclops is cyc. Numbers should generally not be used in naming a gene identified only by mutation. Zebrafish gene designations should not be preceded by 'Z' or 'Zf'.
