Sometimes, whole exome sequencing or a whole genome sequencing test may detect the presence of an unexpected gene variant. This result may be unrelated to the original purpose for which the genetic testing was carried out. Presence of such a gene variant refers to the secondary finding of the genetic test. Individuals with a secondary finding may not exhibit symptoms related to a genetic condition but may develop the condition later.
How do gene variants contribute to evolution?
Evolution can be understood as the gradual change
