rs601338
FUT2rs601338 is a single-nucleotide polymorphism (SNP) in the FUT2 gene. Genespiral reads it in the Health & Wellness analysis to describe Norovirus Resistance.

An rsID such as rs601338 is the reference number dbSNP assigns to one position in the genome where people commonly differ by a single letter. Raw data exports from 23andMe and AncestryDNA list your two alleles at that position as a genotype - for this marker one of AA, AG, GG. The order of the two letters carries no meaning, so AG and its reverse are the same genotype.
Alleles on this page are written on the forward (plus) strand, matching how consumer raw files report them. Other references sometimes describe the same variant on the opposite strand, which swaps A↔T and C↔G - see why the same variant can look different. The associations below are educational summaries of published research; they are not diagnoses, and the effect of any single SNP is usually modest.
Norovirus Resistance
Infectious Disease Resistance · Part of the Health & Wellness analysis
Determines secretor status, impacting susceptibility to norovirus infections.
| Genotype | Association |
|---|---|
| AA | Resistant (Non-Secretor) |
| AG | Susceptible |
| GG | Susceptible |
- Summary
- FUT2 variations affect susceptibility to norovirus, with non-secretors showing resistance.
- Scientific insights
- 'AA' genotype is associated with resistance to certain norovirus strains.
- Lifestyle tips
- Practicing good hygiene is essential for reducing viral exposure risk.
