genomic variants

Genomic variants are differences in the DNA sequence among individuals. These can occur naturally and contribute to the diversity in traits, such as eye color or susceptibility to certain diseases. Variants may be small changes in a single DNA letter (called single nucleotide polymorphisms) or larger alterations affecting sizable regions of a chromosome. While most variants are harmless, some can influence health, leading to conditions or affecting how our bodies respond to medications. Understanding these variants helps researchers explore genetic disorders and develop personalized treatments in medicine.
