A;C

Although reported reasonably credibly in the scientific literature as a dominant mutation leading to Alzheimer's disease, Promethease users with raw data from the 23andMe v4 chip appear to have this genotype reported more frequently than public databases would predict (or than is seen in raw data from other companies). Anyone with follow-on confirmatory testing (positive or negative) for this genotype is encouraged to contact us. See links via rs63749964
