Another term that could be used is gene mutation, which is a change in the genetic sequence that alters the function of a gene. Deletion of a gene can affect the expression of certain traits or cause various genetic disorders. It is important to study and understand gene deletion as an integral part of genetic research and advancements in medical treatments.
