Consumer Genetic Testing
Consumer Genetic Testing

... Many of the DTC genetic tests currently offered to consumers are marketed as being predictive. However, tests for predisposition to complex disorders are only as good as the GWAS (Box 1) on which they are based and there are growing concerns about the validity of some such studies. For instance, the ...

Quantitative trait locus

A quantitative trait locus (QTL) is a section of DNA (the locus) that correlates with variation in a phenotype (the quantitative trait). The QTL typically is linked to, or contains, the genes that control that phenotype. QTLs are mapped by identifying which molecular markers (such as SNPs or AFLPs) correlate with an observed trait. This is often an early step in identifying and sequencing the actual genes that cause the trait variation.Quantitative traits are phenotypes (characteristics) that vary in degree and can be attributed to polygenic effects, i.e., the product of two or more genes, and their environment.
