An rsID such as rs5757241 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 TT, TC, CC. The order of the two letters carries no meaning, so TC 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 Efficiency
Sleep Quality · Part of the Sleep analysis
Regulates arousal and relaxation, impacting the proportion of time spent asleep while in bed.
| Genotype | Association |
|---|---|
| TT | Higher sleep efficiency |
| TC | Moderate sleep efficiency |
| CC | Lower sleep efficiency |
- Summary
- Variations in ADRB1 gene influence sleep efficiency and depth of sleep.
- Scientific insights
- 'TT' genotype individuals tend to spend a higher proportion of time asleep while in bed.
- Lifestyle tips
- Limiting screen time before bed can improve sleep efficiency.
