rs1805319
PER3rs1805319 is a single-nucleotide polymorphism (SNP) in the PER3 gene. Genespiral reads it in the Sleep analysis to describe Sleep Quality.

An rsID such as rs1805319 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.
Sleep Quality
Sleep Quality · Part of the Sleep analysis
Involved in regulating circadian rhythms, affecting sleep quality.
| Genotype | Association |
|---|---|
| AA | Better sleep quality |
| AG | Average sleep quality |
| GG | Poorer sleep quality |
- Summary
- PER3 variations influence overall sleep quality and restfulness.
- Scientific insights
- Those with 'AA' tend to report better sleep quality than those with 'GG'.
- Lifestyle tips
- Keeping a consistent sleep schedule can improve overall sleep quality.
