Your DNA file reports your genotype at rs1801133 — a marker in the MTHFR gene that studies link to folate processing (c677t). Here's what each genotype is associated with:

GenotypeWhat it's associated with
GGTypical MTHFR (C677T) activity — normal folate processing.
AGOne C677T variant — mildly reduced folate enzyme activity.
AATwo C677T variants — reduced folate processing; folate-rich foods may matter more for you.

Educational only — not medical or diagnostic advice. A single marker is one of many factors; strand orientation varies between files. Always consult a qualified clinician about your health.
