    ### Instruction:
    Is alpha-1 antitrypsin deficiency inherited ?
    ### Response:
    This condition is inherited in an autosomal codominant pattern. Codominance means that two different versions of the gene may be active (expressed), and both versions contribute to the genetic trait.  The most common version (allele) of the SERPINA1 gene, called M, produces normal levels of alpha-1 antitrypsin.
