I recently (January 2015) had a Bracia test to see if I had the breast cancer gene. I did not, but under variants of uncertain significance the PMS2 gene came up with the following information under the heading: variant of uncertain significance category...c.335G (then the greater than symbol) A (p.Ser112Asn). I m trying to understand what that means. Currently I have a terrible headache, nauseousness, severe dizziness, and tiredness. I ve had these symptoms before, but not this extreme. Thank you for any information you can provide.
