rs2838171
GABRA2rs2838171 is a single-nucleotide polymorphism (SNP) in the GABRA2 gene. Genespiral reads it in the Personality analysis to describe Impulse Control.

An rsID such as rs2838171 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 GG, GA, AA. The order of the two letters carries no meaning, so GA 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.
Impulse Control
Behavioral Traits · Part of the Personality analysis
Associated with GABA receptor function, influencing inhibitory control and impulse regulation.
| Genotype | Association |
|---|---|
| GG | Better impulse control |
| GA | Moderate impulse control |
| AA | Weaker impulse control |
- Summary
- GABRA2 gene variations can affect one's ability to regulate impulsive behaviors.
- Scientific insights
- Individuals with 'GG' may have stronger impulse control and better decision-making under pressure.
- Lifestyle tips
- Practicing mindfulness and self-regulation techniques can enhance impulse control.
