Navigating SNP & gene pages
Your SNP & gene pages show what genotypes you have for different genetic variants (SNPs):
What Each Column Means in the SNP Table
| Column | Description |
|---|---|
| Variant (SNP) | Pronounced “snips,” these are Single Nucleotide Polymorphisms (SNPs) — tiny changes in your DNA. Watch this video to learn more about SNPs. |
| Genotype | The specific alleles (variants) you carry for this SNP. |
| Frequency | Also called allele frequency. This shows how common this allele is in a population, based on the ethnicity you selected when signing up. |
| Alternative Allele | The allele that differs from the reference sequence. Learn more about alternative alleles here. |
| Impact | A score that shows how strongly this SNP affects the gene. Higher scores indicate greater impact. |
Understanding the Icons on SNP & Gene Pages
Icons on your SNP and gene pages provide extra context:
- ℹ️ Informational Tooltip – A small “i” inside a circle gives general information about insertions and deletions (INDELs). This appears for everyone and does not mean you personally have that INDEL.
- 🟣 Human Icon – A purple-filled icon with a human symbol is specific to your results. It appears next to the alleles you carry, highlighting variations in your genetic data.
These icons help you distinguish between general genetic information and your personal genetic insights, making it easier to interpret your results accurately.
