PURSER WELLNESSWhat Happens If You Have A Gene SNP?A conversation with Dr. Purser

Genetic SNPs are tiny changes in your DNA that can drastically affect how well your enzymes and proteins work. For example, being homozygous for MTHFR C677T leaves that enzyme functioning at only about 30% efficiency, which can drain your energy and impair folate processing. Similarly, errors in SOD genes reduce your body’s ability to neutralize free radicals. While we can’t change your genes, we can work around them by identifying these weaknesses and filling the gaps with targeted nutrition and supplementation—helping your body function closer to its full potential.

Genetic variations in the MTHFR gene can affect the activity or function of the enzyme. The most well-known genetic variants are known as MTHFR C677T and MTHFR A1298C. These variations can lead to reduced enzyme activity, impacting the body

HFE helps regulate iron absorption through signaling that influences hepcidin. The commonly discussed C282Y and H63D variants correspond to rs1800562 and rs1799945. Their implications depend on the combination present and clinical findings.

NAT2 encodes N-acetyltransferase 2, which helps process certain drugs and other compounds. Combinations of variants can influence acetylation status; one SNP usually does not tell the entire story.
