Without enough functional alpha-1 antitrypsin, neutrophil elastase destroys the small air sacs in the lungs (alveoli) and causes lung disease. Excessive damage to the alveoli leads to emphysema, an irreversible lung disease that causes extreme shortness of breath.ore than 120 mutations in the SERPINA1 gene have been identified. Some of these mutations do not affect the production of alpha-1 antitrypsin, while others cause a shortage (deficiency) of the protein.
Another. type of drug that can cause an abnormally low neutrophil count is phenylbutazone, which is a drug used to. reduce inflammation in conditions such as arthritis (inflammation of bone joints). Another cause of a low neutrophil count is too little vitamin B12 or folic acid (a type of vitamin) in the body. A vitamin is one of a group of substances made up partly of carbon (an element) that are essential in small. amounts for normal bodily functioning and chemical processes in the body to take place.
