What's the difference between Genes and Variants, and why does that matter?

A ‘Gene” is a segment of your DNA. “Variants”(Alelles) occur when there is a difference between people in the DNA sequence at a specific locations within a gene. While individuals have similar characteristics, they are rarely identical, the difference between them are called Variations (Alelles). Genetic variation results in different forms, or alleles, of genes. Variants impact the capacity utilization, speed and personal response to drugs by each individual.
