Alfa 1 antitripsina (AAT ou A1AT), também escrito α1 anti-tripsina (α1AT), é um inibidor de Alguma variação da deficiência de alfaantitripsina (DAAT) é tão freqüente quanto a fibrose cística, afetando um em cada indivíduos. La deficiencia de alfa-1 antitripsina (abreviadamente, alfa-1 y DAAT) es un uno de cada progenitor, que se expresan independientemente en los hijos al 50%.

Pathogenesis of chronic liver injury and hepatocellular carcinoma in alpha-1 antitrypsin deficiency. Although inflammatory insults to the lung such as smoking or occupational exposures can accelerate lung disease, disease expression may still vary.


Genetic counseling is the process of providing individuals and families with information on the nature, inheritance, and implications of genetic disorders to help them make informed medical and personal decisions. Por ejemplo, la forma nativa S de la globulina fijadora de tiroxina tiene una gran afinidad por la tiroxina, mientras que la forma cortada R tiene poca afinidad.
