Abstract:
The use of advanced recombinant DNA technology has provided an improved understanding of the human AAT deficiency phenotype by providing the amino acid sequence of several variant proteins and by allowing for the production of various cell and animal models to study the molecular and biochemical components of the retention, degradation, and accumulation of these variants in the hepatic ER. Human AAT deficiency will continue to serve as an excellent model for enhancing our current understanding of mechanisms utilized in regulating protein "traffic" in the ER and in elucidating the pathophysiologic components of AAT-related liver disease.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
