In some cases, however, the number of copies variesâmeaning that a person can be born with one, three, or more copies of particular genes. Less commonly, one or more genes may be entirely missing.ften, gene mutations that could cause a genetic disorder are repaired by certain enzymes before the gene is expressed and an altered protein is produced.
