Genetic Variance Assessment is the clinical evaluation of an individual’s unique variations in their DNA sequence, specifically focusing on single nucleotide polymorphisms (SNPs) and other genetic differences that influence metabolic, hormonal, and physiological responses. This assessment moves beyond basic disease screening to identify subtle genetic predispositions that impact nutrient absorption, detoxification capacity, and endocrine signaling efficiency. It provides the biological blueprint for highly personalized health interventions.
Origin
This term is a clinical application of population genetics and molecular biology, recognizing that slight variations in genes can significantly alter protein function and systemic health trajectories. The assessment’s utility in hormonal health stems from the knowledge that genetic variants, such as those affecting CYP enzymes or hormone receptors, dictate an individual’s specific needs for vitamins, hormones, and pharmacological agents. It is the foundation of precision dosing and therapeutic selection.
Mechanism
The assessment typically involves sequencing specific genes or panels of SNPs relevant to health and longevity, such as those involved in the methylation cycle or estrogen metabolism. By identifying a variant, the clinician can predict a functional outcome, for example, a reduced enzyme activity, which then dictates a targeted intervention, such as supplementation with the end-product or a cofactor. This mechanistic understanding allows for the correction of genetically-influenced metabolic bottlenecks.
