Why 23andme is NOT A Medical Test: Genetic Sequencing vs SNP testing explained

At-home genetic testing (also called Direct-to-consumer or DTC testing) has become very popular; but do you know the difference between these tests and tests ordered by a medical professional? What are these at-home tests missing?

In this video, you'll learn the difference between genetic sequencing technology (next generation sequencing/NGS) and SNP genotyping. I will illustrate how SNP genotyping is not an appropriate medical test using the example of the BRCA1 and BRCA2 genes on 23andMe. Other terms mentioned include; single nucleotide polymorphism, false negative, and others.

These are not your typical biology videos. This series is for anyone interested in learning about genetic testing today, what it can and can’t test, and how it relates to YOU. Subscribe and check back every Friday for a new short episode explaining something new to know in genetic medicine.
