Before taking a DNA test, you should be prepared for the results. This shows you what a DNA test report looks like and how to read it.
Plain-language definitions of core genetics terms used on Sequencing, from DNA, genes and chromosomes to alleles, SNPs, variants and genotype vs phenotype.
DNA 101 is your resource for learning about DNA testing, analysis, and, most importantly, how you use the information hidden within genes to live healthier, happier, and longer.
Single gene disorders follow one variant, while multifactorial conditions such as hypertension, diabetes and asthma combine genes, lifestyle and environment.
As their name implies, multifactorial diseases, or multifactorial inheritance, are conditions that are caused by multiple factors.1 These can include a wide range of genetic,…

Heredity is not destiny. Genetic testing can help you identify any current or potential health issues associated with your genome so you can live a healthier life.
A genetic counselor is trained in both genetics and counseling, and can interpret DNA results, weigh disease risk against family history and discuss next steps.
