rs3923809
NPSR1rs3923809 is a single-nucleotide polymorphism (SNP) in the NPSR1 gene. Genespiral reads it in the Sleep analysis to describe Restorative Sleep.

- Traits
- 1 trait across 1 analysis
An rsID such as rs3923809 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.
Restorative Sleep
Sleep Quality · Part of the Sleep analysis
Associated with sleep architecture, influencing the refreshing quality of sleep.
| Genotype | Association |
|---|---|
| AA | More likely to experience restorative sleep |
| AG | Moderate restorative sleep |
| GG | Less likely to experience restorative sleep |
- Summary
- NPSR1 gene variations may affect the feeling of restfulness upon waking.
- Scientific insights
- 'AA' genotype is linked to a greater likelihood of feeling refreshed after sleep.
- Lifestyle tips
- Engaging in deep relaxation before bed can promote restorative sleep.
