What is rs174561?
rs174561 is a single-nucleotide polymorphism (SNP) in the FADS1 gene (Fatty acid desaturase 1). Each person carries two copies, one from each parent, so a result is reported as a pair of letters such as CT. The table below describes what studies associate with each genotype; the association is statistical, across populations, and is not a diagnosis.

Is rs174561 on 23andMe and AncestryDNA chips?
Yes — it is genotyped directly on 23andMe V5. Orviva reads it from a raw-data export without imputation.

Genetic associations describe risk across populations, not a diagnosis for any one person. Most variants shift risk modestly and act alongside lifestyle, environment and other genes. Consumer DNA chips do not read every position and can be wrong at any single one. For general education only; talk to a clinician or genetic counsellor before acting on anything here, and never change a prescribed medicine without your prescriber.
