Did Michael Jackson have alpha-1 antitrypsin deficiency? In December 2008, rumors surfaced from a biography by Ian Halperin that Jackson needed a lung transplant because he had alpha-1 antitrypsin deficiency (A1AD).
Alpha-1 antitrypsin (AAT) is a protein produced by the liver that acts to protect various organs including the lungs. When a person inherits A1AD, their body produces proteins that are deformed which can also lead to liver disease. An estimated 1 in every 1,600 people to 1 in every 5,000 people have A1AD.
DNA tests for A1AD are available that look at alleles of the SERPINA1 gene (see Genetics Home Reference). People with two copies of the M allele (MM) have normal levels of AAT. Those with two copies of the Z allele (ZZ) are at highest risk of developing severe symptoms including lung disease and liver disease especially if they smoke.
Other illnesses Jackson may have suffered from:
- Flesh eating disease caused by a staph infection following cosmetic surgery.
- Skin cancer
- Costochondritis, inflammation of the cartilage at the front of the ribs
- Addiction to painkillers
- Vitiligo, an autoimmune disorder that affects the pigment-producing cells of the skin
- Abnormal heart rhythm
- Back spasms
Autopsy results may or may not tell us whether Michael Jackson had A1AD or other inherited disorders. Hopefully he was receiving any treatments he may have needed.
