Figure 1From: Genetic variants of chemokine receptor CCR7 in patients with systemic lupus erythematosus, Sjogren's syndrome and systemic sclerosisSchematic overview of the CCR7 gene located at chromosome 17q12 – q21.2. The enlarged areas represent the three exons with their flanking regions that have been subjected to sequence analysis. The positions of the observed SNP are given in relation to the first base of exon 1 which has been set to +1.Back to article page
