    Description of a new rare alpha-1 antitrypsin mutation in Naples (Italy): PI*M S-Napoli.
    Ann Thorac Med 2018 Jan-Mar;13(1):59-61
    Department of Clinical Medicine and Surgery, Federico II University Hospital, Naples, Italy.
    Alpha-1 antitrypsin deficiency is a rare and often underdiagnosed hereditary disorder, which mainly affects the Caucasian population. We report a case of a noncystic fibrosis bronchiectasis patient in the absence of emphysema associated with low serum alpha-1-antitrypsin (AAT) level, in the absence of the most common defective alleles associated with AAT deficiency (PI*S and PI*Z) but with a new mutation in heterozygosis. This mutation is characterized by the substitution in the coding region of exon 3, of a guanine (G) for a thymine (T), generating the replacement of a glutamine (Gln) by a histidine (His) in codon 212 (cod 212 GlnCAG > HisCAT), corresponds to a new S allelic variant.
