Segregation distortion of the alpha 1-antitrypsin Pi Z allele.

American journal of human genetics, 1979
alpha 1-antitrypsin (alpha 1AT) of the Pi type Z is associated with two diseases: pulmonary emphysema and cirrhosis of the liver. We report 23 families with both parents heterozygous for the PiZ allele, characterized from our own analysis and from world literature sources. All families were identified through members expressing disease.

Molecular markers linked to the blast resistance gene Pi-z in rice for use in marker-assisted selection

Theoretical and Applied Genetics, 2003
Rice blast, caused by the fungal pathogen Pyricularia grisea, is a serious disease affecting rice-growing regions around the world. Current methods for identification of blast-resistant germplasm and progeny typically utilize phenotypic screening. However, phenotypic screens are influenced by environmental conditions and the presence of one resistance ...

Natural History and Life Expectancy in Severe Alpha1‐Antitrypsin Deficiency, Pi Z

Acta Medica Scandinavica, 1978
ABSTRACT. Clinical data from 246 adult Swedish individuals with severe α1‐antitrypsin deficiency, Pi Z, diagnosed in 1963‐77, were analyzed. Primary emphysema was present in 109 cases. Of 75 Pi Z patients with other types of chronic obstructive pulmonary disease (COPD), all but 7 showed signs of emphysema.

DNA restriction fragments associated with α1-antitrypsin indicate a single origin for deficiency allele PI Z

Nature, 1985
The alpha 1-protease inhibitor, or alpha-antitrypsin (AAT), a major plasma inhibitor of leukocyte elastase and bacterial proteases, is encoded at the PI locus on chromosome 14 (14q24.3-q32.1). A deficiency of AAT in individuals homozygous for the PI Z allele occurs in about 1 in 2,000-8,000 caucasians and is associated with an increased risk of early ...

Absence of the alpha-1-antitrypsin PI*Z allele in Tunisia substantiates the particular genetic structure of African populations

American Journal of Human Biology, 1997
Alpha-1-antitrypsin (PI) phenotypes were studied in a sample of 450 Tunisians. The observed frequencies of PI alleles were identical to those in African populations, with a very low incidence of PI*S and virtual absence of PI*Z. Such figures are similar to estimates in Asians and clearly opposite to those in Europeans. Am. J. Hum. Biol. 9:223-224, 1997.

Familial alpha-1-antitrypsin dificiency with Pi-Z and a new Pi-Gcler variant.

Biomedicine / [publiee pour l'A.A.I.C.I.G.], 1981
A case of familial deficiency in alpha-1-antitrypsin connected with Pi-0Z gene led to the finding of a new Gcler variant partly deficient, the electrofocusing pattern of which, located between that of G and I variants, was modified after neuraminidase digestion.

High-Speed Detection of α1-Antitrypsin Deficiency Alleles Pi*S and Pi*Z on the LightCycler

2001
Protease inhibitor 1 (αl-antitrypsin, AT) is the main serum inhibitor of proteolytic enzymes. In AT-deficiency, enzymes such as neutrophil elastase can damage the lung tissues, leading to pulmonary emphysema. More than 90 different alleles have been identified so far for the protease inhibitor 1 (PI) gene.
