Variant discovery

Variant discovery is a process used by scientists to identify differences in DNA sequences among individuals. By comparing a person's DNA to a reference genome, researchers can detect genetic variations such as mutations or differences in the order of building blocks (like letters in a code). These variations can influence traits, health, or disease risks. The process involves sequencing DNA, analyzing the reads, and pinpointing specific locations where the genetic code differs from the reference, helping researchers understand genetic diversity and identify potential genetic factors related to health and traits.
