The use of genetic test, as pre-symptomatic testing of diseases, has gained popularity in predicting future risks by providing information on an individual's chromosomes and genetic mutations. Predictive genetic testing is relatively new but rapidly emerging arena in public health practices, especially in developed nations. It is increasingly being used to guide nutritional strategies and training outcomes for a number of disorders. Common disorders include Huntington's disease, cystic fibrosis, phenylketonuria, Down's syndrome, breast cancer, and sickle cell anemia. Usually conducted in healthy persons, it involves identifying certain genetic traits that may cause disease in later years of life. Some of the most common types of predictive genetic testing can be genetic susceptibility testing, predictive diagnostic, and population screening. They may be useful in persons who have family history of some treatable genetic disorders. Consumer genomics usually involves the application of whole genome sequencing essentially to classify individuals in various risk types for a variety of diseases. While wellness genomics is used to assist persons to take appropriate health decisions that promotes their wellness and help in maintenance of better health. It typically includes various genotypic and clinical information. Coupled with preventive medicines, wellness and consumer genomics form a key role in guiding health and wellness decisions in various populations.
