Alpha-1 Antitrypsin Deficiency report: Impact and diagnosis

Written by Sano Marketing Team | Jul 27, 2023 5:32:27 PM

Our latest insights report focuses on Alpha-1 Antitrypsin Deficiency (AATD), a rare genetic disorder with significant implications for both lung and liver health. AATD arises from a deficiency of the alpha-1 antitrypsin (AAT) protein, which safeguards the lungs from inflammation and damage. With this protein in short supply, the lungs become vulnerable to conditions like emphysema and chronic obstructive pulmonary disease (COPD), with symptoms that often include chronic cough, shortness of breath, and wheezing. Environmental exposures, including smoking, air pollution, and occupational dust, can significantly accelerate lung damage in individuals with low AAT levels. Beyond the lungs, AATD can also lead to liver scarring, known as cirrhosis, as the misfolded AAT protein accumulates in liver cells rather than entering the bloodstream.

AATD is caused by changes in the SERPINA1 gene, which carries the instructions for producing the AAT protein. These gene changes are inherited, meaning AATD runs in families. An individual who inherits two altered copies of the gene, one from each parent, is at risk of developing clinically significant disease. Those who carry a single altered copy may have reduced AAT levels and can pass the variant to their children, often without knowing they carry it.

Because AATD symptoms overlap with more common respiratory conditions, many individuals remain undiagnosed or receive a delayed diagnosis, sometimes by years. This diagnostic gap makes genetic testing a critical step in identifying affected individuals and connecting them with appropriate care or research opportunities.

Key Takeaways

  • Alpha-1 Antitrypsin Deficiency (AATD) is a rare genetic disorder that primarily affects lung and liver health.

  • The condition is caused by a deficiency in the alpha-1 antitrypsin protein, which is essential for protecting lungs from inflammatory damage.

  • Low levels of this protein increase the risk of developing emphysema and chronic obstructive pulmonary disease (COPD).

  • The insights report covers global prevalence, diagnostic challenges, and the current landscape of genetic research.

Our report sheds light on:

  • AATD prevalence: Its impact on global health.

  • Diagnostic hurdles: The challenges in identifying the condition early.

  • Clinical landscape: Available treatments and ongoing genetic research.
