Alpha-1 Antitrypsin Deficiency (AATD) Market New Product Development & Latest Trends

Introduction
Alpha-1 antitrypsin deficiency (AATD) is a rare genetic disorder caused by mutations in the SERPINA1 gene, leading to low levels of the alpha-1 antitrypsin (AAT) protein. This protein normally protects the lungs from neutrophil elastase; deficiency results in early-onset chronic obstructive pulmonary disease (COPD), emphysema, and liver disease.

Despite affecting an estimated 1 in 2,500-5,000 people of European descent, AATD is significantly underdiagnosed due to overlapping symptoms with asthma and COPD. However, growing awareness, advanced diagnostic techniques, and emerging therapies are transforming the AATD market. Expanding augmentation therapies, gene therapies, and novel biologics are fueling optimism for patients and healthcare providers.
