rs4684847
CACNA1Crs4684847 is a single-nucleotide polymorphism (SNP) in the CACNA1C gene. Genespiral reads it in the Sleep analysis to describe Sleep Onset Latency.

An rsID such as rs4684847 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 Onset Latency
Sleep Patterns · Part of the Sleep analysis
Affects calcium channels in the brain, potentially influencing sleep onset timing.
| Genotype | Association |
|---|---|
| TT | Faster sleep onset |
| TC | Moderate sleep onset |
| CC | Slower sleep onset |
- Summary
- Variations in CACNA1C may be related to differences in time to fall asleep.
- Scientific insights
- Individuals with 'TT' tend to fall asleep faster compared to those with 'CC'.
- Lifestyle tips
- A calming pre-sleep routine may help with faster sleep onset.
