Test
Clinical Utility
Normal metabolism of methionine is critical for cellular methylation of DNA, proteins and neurotransmitters. Aberrant methionine metabolism can occur in anyone at any age and can be associated with numerous health consequences including cardiovascular disease and cancer. The Methylation Profile provides a functional assessment of the phenotypic expression of common SNPs (MTHFR, MS, CBS) by evaluating the plasma levels of methionine, cysteine, SAM, SAH, homocysteine and cystathionine, and provides the important “methylation index,” a ratio of SAM to SAH.
