Increased exacerbations and hospitalizations among PI*MZ compared to PI*MM individuals: an electronic health record analysis

Increased exacerbations and hospitalizations among PIMZ compared to PIMM individuals: an electronic health record analysis

Abstract Background The best described endotype of COPD is alpha-1 antitrypsin (AAT) deficiency, due to a genetic abnormality in the SERPINA1 gene. Common deficient PI variants are the Z and S variants. Homozygotes for the Z allele (PI*ZZ individuals) carry the genotype most commonly associated with...
