Familial alpha-1-antitrypsin dificiency with Pi-Z and a new Pi-Gcler variant. 1980

M P Plazonnet, and J Constans, and G Misson, and C Gentou

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. A study of three generations shows that Gcler variant is transmitter according to an autosomally codominant mode. Moreover serum trypsin inhibitory capacity and concentration of ten proteins have been measured in this family. Except the known relation between serum alpha-1-antitrypsin level and trypsin inhibitory, capacity, only serum IgA showed a significant correlation with serum alpha-1-antitrypsin in the deficient group with Pi-Z allele.

UI MeSH Term Description Entries
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
