Is Depression Genetic?

Genetic Factors Behind Depression

Research has identified multiple genetic variants that influence a person's susceptibility to Depression. While no single gene determines whether someone will develop this condition, specific variants can increase or decrease risk. Key genes studied in relation to Depression include:

Each of these genes plays a distinct role in the biological pathways related to Depression. Variants in these genes have been identified through large-scale genome-wide association studies (GWAS) and replicated across multiple populations.

How GenomeInsight Analyzes Your Risk

GenomeInsight examines your raw DNA data from services like 23andMe, AncestryDNA, or whole-genome sequencing (VCF files) to identify genetic variants associated with Depression. The analysis is performed entirely in your browser, meaning your genetic data never leaves your device.

For each relevant variant, GenomeInsight reports your genotype, the associated risk allele, the odds ratio from published research, and your overall risk profile compared to the general population. Results are presented with easy-to-understand risk visualizations and percentile rankings.

Genetic risk is only one piece of the puzzle. Lifestyle, diet, environment, and family history all contribute to overall risk. GenomeInsight's analysis is for informational and educational purposes and is not a medical diagnosis.

Understanding Your Depression Results

After uploading your DNA file, you will receive a detailed health risk report covering 52 conditions, including Depression. For each condition, GenomeInsight analyzes multiple SNPs (single nucleotide polymorphisms) and calculates a combined risk assessment.

Your results will show whether you carry risk-increasing or protective alleles in genes like SLC6A4, BDNF, HTR2A, and FKBP5. Risk levels range from "Below Average" to "Significantly Increased," with population percentile comparisons to contextualize your results.
