Results The mutation incidence of LKG was 22.96%, while the mean incidence of GPG was 7.59%(The incidences of C20-OH group, glucoside group and aglucon group were 5.32%, 6.25% and 11.00% respectively).

Alpha-1 antitrypsin is the most abundant circulating protease inhibitor in the body, Dr. Lomas said. Its most common deficiency mutation is the Z allele, where the amino acid lysine is exchanged for glutamic acid at position 342 in the polypeptide chain (Glu342Lys). About 1 in 1700 whites of northern European descent are homozygotes for this mutation and thus have plasma antitrypsin levels that are 10% to 15% below normal, he said.
