Genetic Variation & Disease: Direct-to-Consumer Genetic Testing

Learn about variants in the human genome and how consumer based testing provides information on patient risk.

The variation in a person’s genome impact DNA and individual risks for medical conditions. Learn about genetic variants and two common types of genetic technology used to identify them, genotyping and sequencing. Common genetics terms are defined, including polygenic scores, variable expressivity, non-penetrance, GWAS, and DTC testing.
