Poster: Alpha-1 Antitrypsin Deficiency: Why millions remain undiagnosed

Alpha-1 antitrypsin deficiency (AATD), a rare genetic condition, can cause lung disease in adults with symptoms similar to chronic obstructive pulmonary diseases. AATD is largely underdiagnosed, with an estimated prevalence of 100,000 individuals with AATD in the United States (US); however, fewer than 10,000 individuals are diagnosed with the disorder. Previously, AATD was thought to affect only White individuals of European descent. Recent studies have shown that people of different races and ethnicities have genotypes consistent with those with moderate-to-severe AATD-related lung disease. We developed a prediction model to identify symptomatic patients of different races and ethnicities with likely risk of AATD using claims data from a large US database. This poster was developed together with Takeda and presented at the American Thoracic Society International Conference 2024.
