What is the Meaning of Genetic Variations?

Genetic variations are the natural differences in the DNA sequence among individuals, including single nucleotide polymorphisms (SNPs), insertions, deletions, and structural changes. These variations contribute to the unique physical characteristics and predispositions to certain health conditions observed across the human population. Understanding an individual's specific genetic profile is fundamental to personalized medicine and targeted health interventions.

What is the Origin of Genetic Variations?

The concept of variation is central to evolutionary biology, but the molecular basis for genetic variations was established with the discovery of DNA structure and the mapping of the human genome. The term 'genetic' is from the Greek genesis (origin), and 'variation' is from the Latin variatio (change). The clinical utility of studying these variations accelerated dramatically with modern, high-throughput sequencing technologies.

What is the Mechanism of Genetic Variations?

Genetic variations influence health outcomes by altering the structure or expression of proteins, including enzymes, receptors, and transporters. For example, a SNP in a gene coding for a metabolic enzyme might lead to slower drug clearance or altered hormone breakdown pathways. These subtle differences in protein function can modulate an individual's response to diet, exercise, environmental exposures, and hormonal therapies, dictating the optimal approach for personalized care.
