ABSTRACT Alpha-1 antitrypsin deficiency (AATD) is a rare genetic disorder caused by a mutation in the SERPINA1 gene, which encodes the protease inhibitor alpha-1 antitrypsin (AAT). Severe AATD predisposes individuals to COPD and liver disease. Early diagnosis is essential for implementing preventive meas...
Resumen La deficiencia de alfa-1 antitripsina (AAT) es uno de los trastornos hereditarios más frecuentes y con mayor incidencia en pacientes con enfermedad pulmonar obstructiva crónica (EPOC). Se desconoce su prevalencia en aquellos con neumotórax espontáneo. El objetivo fue estimar la prevalencia de...
ABSTRACT Objective: The clinical, functional, radiological and genotypic descriptions of patients with an alpha-1 antitrypsin (A1AT) gene mutation in a referral center for COPD in Brazil. Methods: A cross-sectional study of patients with an A1AT gene mutation compatible with deficiency. We evaluated th...
Alpha-1 antitrypsin deficiency (AATD) is a genetic disorder caused by a mutation in the codifying
gene for the alpha-1 antitrypsin (AAT) protein, which has anti-elastase activity. While there is
extensive genetic variability, the most common genotypes associated with AATD are PI*Z y
PI*S. Most clinical m...
A deficiência de alfa-1 antitripsina é um distúrbio de herança autossômica codominante que afeta principalmente pulmão e fígado. É uma das mais comuns de desordens genéticas, não sendo frequentemente reconhecida. O caso relatado é de uma mulher de 69 anos, com história de dor e aumento do vol...
