I was just recently tested for the MTHFR Mutation gene by my hematologist/oncologist, the test came back POSITIVE FOR ONE COPY OF THE A1298C MUTATION, what does that mean and how will that affect my currently blood condition called ITP (Idiopathic thrombocytopenic purpura)? Will I need to make lifestyle changes?

Summarized question: Will positive result in MTHFR mutation test affect ITP condition?
