False, pernicious anemia may take up to 5 years to show symptoms. However, the oxygen starts to get depleted within the first 6 months in thalassemia major.
Pernicious anemia:
In this condition, the body is unable to absorb vitamin B12 which leads to lowered amount of red blood cells which are responsible for carrying oxygen throughout the body. It is an autoimmune disease in which antibodies attack their own cells in the lining of the stomach which affects the absorption of vitamin B12. The symptoms of pernicious anemia are dizziness, fatigue, diarrhea, constipation, breathlessness, and loss of appetite. The depletion of oxygen is seen in thalassemia major within 6 months.

Gene expression is about making mRNA which is then translated into a protein. If the mRNA that was expressed is mis-read it may or may not have an affect on gene expression. It will have a negative effect if:
1. The protein produced is required for gene expression (e.g. the DNA polymerase)
2. The protein produced is another critical protein that the cell cannot live without.
3. If the question is more about constantly misreading during translation, eventually the cell would die because the wrong proteins would be made (or not made at all).
