In this study, three patients diagnosed with an A1AT deficiency had neonatal cholestasis and in two xntitripsina these, before a definite diagnosis of the deficiency was established, the cholestasis was lediatria idiopathic.


The objective of this study was to identify S and Z allele carriers in patients suspected of having this deficiency and who showed laboratory and clinical characteristics of this disease.
