Polymerase chain reaction detection of S and Z alpha-1-antitrypsin variants by duplex PCR assay.
A polymerase chain reaction (PCR) assay was used to detect the two most common alpha-1-antitrypsin (A1AT) deficiency variants, S and Z. By co-amplification using primers for both the S and Z mutations, we were able to detect heterozygous and homozygous genotypes for both mutations and normal type M in a single duplex reaction. We validated our assay by comparison with phenotype studies obtained by the standard isoelectrofocusing technique.
