The conclusions from these essentially negative MR findings have, however, been questioned in a well-argued critique 31 , pointing out the limitations of genetic markers that explain only a small component (i.e., 7.7% at most 5 ) of serum UA variance and querying whether the core assumptions of MR, including the absence of confounds as well as a strong association with UA, are met

When it comes to the functioning of your cells, methyl groups are used in methylation reactions.[ref] Examples of methylation reactions include: synthesis of some of the nucleic acid (DNA) bases turning off genes so that they arent transcribed (DNA methylation) converting serotonin into melatonin methylating arsenic so that it can be excreted breaking down neurotransmitters metabolizing estrogen regenerating methionine from homocysteine Methylation in the right amount: For example, you need enough folate (vitamin B9) and methylcobalamin (vitamin B12) for the methionine synthase reaction to occur
