The present disclosure aims to provide a technique capable of accurately detecting a mutant gene and a mutation rate using capillary electrophoresis. A mutant gene detection method according to the present disclosure classifies signal peaks included in a detected signal into a first group that is lower than a first threshold and a second group that is not lower than the first threshold, increases an injection voltage until the signal peak belonging to the first group becomes higher than or equal to the first threshold, and reduces the injection voltage after the increase in the injection voltage until the signal peak belonging to the second group becomes lower than or equal to a second threshold which is higher than the first threshold (see FIG. 7).
A mutant gene detection method of detecting a mutant gene in a nucleic acid sample containing a gene, the method comprising:
