MTHFR... Yep, it gets blamed for a variety of health and pregnancy concerns. But does the data actually confirm the presence of adverse pregnancy and adverse health issues with MTHFR variants? In this session, we will review the difference between the 2 most common variants (C677T, A1298C) and true MUTATIONS. We will also review statements from the ACOG, ACMG, SMFM, as well as the Canadian Guidelines regarding MTHFR screening.
