[Genetic polymorphism of inter-alpha-trypsin-inhibitor (ITI) in a Han population in China]
Abstract
Phenotypes of inter-alpha-trypsin-inhibitor (ITI) have been determined by isoelectric focusing on the polyacrylamide gel followed by immunofixation. The phenotype frequencies of ITI in the Han population in Chengdu, China were investigated using this method. In addition, family studies have been conducted in 21 families. The results showed that the ITI was polymorphic in the Han population in Chengdu. The allele frequencies were as follows: ITI*1 = 0.5763, ITI*2 = 0.4107, ITI*3 = 0.0130. It was obvious that the ITI is a new and promising genetic marker which can be used in the field of forensic haematogenetics.
