Detection of alpha-1-antitrypsin deficiency variants by synthetic oligonucleotide hybridization.
Oligonucleotide probes, specific for the two most common deficiency variants, Z and S, of alpha-1-antitrypsin have been successfully applied for the diagnosis at the DNA-level. The possible presence of silent alleles necessitates a careful study of the parents both at the protein- and DNA-level in prenatal diagnostic cases.
