depends. for example, it could have no effect/be helpful or it could be fatal if it leads to a malformation or lack of production of an important protein.
If the deletion occurs in a section where the DNA encodes for a protein, it will cause what is called a "frame shift". Each amino acid is encoded by a DNA codon which is made up of 3 nucleotides. By deleting a nucleotide (base) the codons are no longer read properly. As such, the subsequent protein is now made with the wrong amino acids. If this protein is critical to cell survival it can lead to cell death. There are also regions of DNA that control protein expression which if mutated by a base deletion will cause misregulation of protein expression. Fortunately however, a large percentage of DNA actually does not appear to code for anything. As such, a deletion in this part of the DNA tends not to have any affect at all.
The deletion of a single nitrogen base in a particular gene will cause the rest of the genetic code for that particular gene to become senseless, and the protein that is supposed to be formed from that code will be useless. If this occurs in a gamete, then the resulting offspring can inherit a genetic disorder, or may not even be able to survive very long after fertilization. If this happens in a body cell, a tumor, including a cancerous tumor could result.

the deletion or addition results in a mutation
The only effect know to affect DNA is mutation. mutation occurs as a result of the deletion or change is the codon of a base sequence, they can occur either in keto form or the enol form.And there are different mutagent capable of altering the base sequence of a DNA,the transition , transversion and frame shift. And this causes a change in the morphology of a particular organism.-prince david adedeji

A mutation in a gene can happen by addition, deletion or substitution of base pairs. This means that the order of the bases will change- a new base may be added, a base may be lost, or one base may be substituted for another. The result of these mutations is that it causes the DNA to code for a different protein. If a mutation occurs in a sex cell, the mutation can be passed on to an offspring and affect the offspring's phenotype.
