openSNP

openSNP provides an open repository of Direct‑To‑Consumer (DTC) Single Nucleotide Polymorphism (SNP) genotype data and associated phenotypes to enable population‑scale genetic association analyses such as genome‑wide association studies (GWAS).

Key Features:

• Data publication and sharing: Accepts user-uploaded DTC SNP genotype files and associated phenotypic metadata for open release and aggregation.
• Facilitating GWAS: Aggregates crowd‑sourced genotypes and phenotypes to support GWAS and the identification of statistically significant SNP–trait associations.
• Community engagement and collaboration: Connects individuals reporting similar genetic variants and supports community-contributed phenotype information for collective analysis.
• Access to scientific literature: Links reported variants to relevant primary scientific literature to aid interpretation of genotype–phenotype relationships.

Scientific Applications:

• Genome-wide association studies (GWAS): Enables GWAS by providing aggregated DTC SNP genotypes and phenotypes to increase sample size and statistical power for detecting SNP–trait associations.
• Population genomics and personalized medicine: Supports population-scale analyses and exploratory studies in genomics and personalized medicine by making open genotype–phenotype data available, including integration of large aggregated cohorts (e.g., datasets from over 100,000 individuals reported in the platform).

Methodology:

Aggregates user-uploaded DTC SNP genotype files and self-reported phenotypic data into an open repository to enable statistical association analyses such as GWAS.
