    I am looking for a code for MTHFR gene mutation. I have narrowed it down to 270.3 or 270.4 I think. Does anybody have any expertise or thoughts on this? Thanks for your help.

    What is the official name of the MTHFR gene?
    The official name of this gene is “5,10-methylenetetrahydrofolate reductase (NADPH).”

    MTHFR is the gene's official symbol. The MTHFR gene is also known by other names

    We use code 289.7
