  • Methods and kits for detecting gene mutations
    Patent number: 10851408
    Abstract: The invention relates to methods, kits and uses thereof for detecting gene mutations. The method comprises the step of: providing a mixture of nucleic acid molecules comprising both a genomic DNA and a RNA molecule derived from said genomic DNA, performing a reverse transcription reaction with a reverse transcriptase to provide cDNA molecules from said RNA molecule in said mixture; and performing PCR using both said genomic DNA and said cDNA molecules as templates. This method can simultaneously detect a trace amount of a mutation in both DNA and RNA from a whole blood sample using a small amount of sample. At the same time, by adjusting the reaction system, the detection limit of a mutant in a background of wild-type molecules can reach 0.01% or lower.
