About genetics testing and precision medicine
Knowledge and understanding of the human genetics have tremendously increased over the last 30 years, notably due to the technology developments such as diverse genetic arrays and next generation sequencing. The elucidation of the human genome allowed subsequently to sequence the genome of a big number of individuals and diverse human ethnicities, to compare them among each other, to establish a haplotype map of the human genome and, to identify sequences that are related to a disease development.
The DNA sequence of any two people is 99.9 percent identical. The variations, however, may greatly affect an individual's risk to develop a disease.
Over the last few years, Gene Predictis has developed diverse genetic tests specifically for Clinique La Prairie, allowing to the Clinic to establish a highly personalized follow-up for its clients, as well as to propose them a highly personalized disease prevention. These tests are based upon proprietary algorithms and target complex diseases or complex traits that are determined at the same time by one or multiple genetic variants and the environment (e.g. food intolerances, diabetes, cardiovascular disease, nutrition, ageing...). Development of a complex disease depends on the equilibrium between the risk and the protective factors which may be genetically or environmentally determined. This postulate is the basis for actionable preventive treatments – one cannot change his or her genes, but can change lifestyle according to his/her genetics and thus act to decrease the risk of the disease development.
Genetics can help to decrease oxidative stress or to predict the risk of developing deficiency in diverse nutriments, such as vitamins.
Some examples :
Folate or vitamin B9 is only available through nutrition and plays an important role in the formation of red blood cells and in the healthy growth and function of cells (synthesis of DNA bases, synthesis of certain amino acids, etc); it is crucial in early pregnancy to reduce the risk of congenital malformations of the brain and spine.
Folic acid is the metabolic precursor of an important coenzyme, tetrahydrofolate; its biotransformation involves a specific enzyme (MTHFR). Genetic variant in this gene that forms this MTHFR enzyme is frequent in the general population. This variant is associated with low serum and red blood cell folate levels, as well as with elevated homocysteine levels (a risk factor for cardiovascular disease and cognitive decline). Knowledge of the existence of this variant in the genome of the person can help to decide on folate supplementation, choice of the most appropriate form of supplements (folate vs. folic acid), allow to establish a personalized surveillance of homocysteine levels to prevent development of certain diseases.
Finally, numerous studies have shown that knowledge of our own genetics and the eventual associated risks stimulates to adopt appropriate healthy lifestyle that significantly contributes to an individual wellbeing and longevity.
Genetics tests are included in the programs Revitalisation, Revitalisation Premium, Master Detox and Weight Loss System.
- Revitalisation’s Better Aging DNA testing: a comprehensive overview of inherited risk factors that enable the tailoring of therapies, as well as nutritional and lifestyle advice based on the genetically predisposed factors.
- Master Detox and Weight Loss System’s Nutri-DNA testing: genetic and nutritional analysis allowing to tailor dietary habits. For detox, it tells the body’s capacity for specific nutrients absorption and elimination, allowing to target bespoke cleansing pathways.
