The interleukin-1 receptor antagonist gene: a single-copy variant of the intron 2 variable number tandem repeat (VNTR) polymorphism.

摘要

A variable number tandem repeat (VNTR) polymorphism exists within intron 2 of the human interleukin-1 receptor antagonist gene, consisting of perfect repeats of an 86-bp sequence. Five allelic variants have been identified wherein the number of repeats varies from two to six. This is the first report of a rare, single-copy allele designated IL1RN*0.
