Sequence homology and structural comparison between the chromosomal human alpha 1-antitrypsin and chicken ovalbumin genes.

The human chromosomal alpha 1-antitrypsin gene has been cloned. This gene is approximately 5 kilobase pairs long and contains three intervening sequences in the peptide-coding region. DNA sequences coding for the amino and carboxyl termini of a alpha 1-antitrypsin have been identified. Human alpha 1-antitrypsin and chicken ovalbumin show significant sequences homology and belong to a common protein super-family. Yet the number, position and size of intervening sequences reveal that the two genes are dissimilar.

Cytochemical differences in leucocytes of normal adult males and females.

Peripheral blood samples were drawn from 50 patients (25 males and 25 females) with no apparent haematologic disorders. Smears were stained for Periodic Acid-Schiff and beta-glucuronidase reactions. Diffuse to moderate activity was observed in leucocytes for both stains. There was a significant difference in males and females in positive reactions in monocytes stained for beta-glucuronidase and in lymphocytes and granulocytes stained for PAS.

alpha 1-antitrypsin deficiency detection by direct analysis of the mutation in the gene.

A deficiency in the plasma protease inhibitor alpha 1-antitrypsin can cause chronic obstructive emphysema or infantile liver cirrhosis. This deficiency results from a single amino acid substitution created by a G to A transition in the gene for alpha 1-antitrypsin. Chemically synthesized specific oligonucleotide probes (19-mer) have been used to develop a sensitive and direct test for the presence or absence of the mutant gene in any individual, which can be used for prenatal diagnosis of the deficiency syndrome.
