Search for a SNP

SNPExpress enables a convenient search for genes.

(1) SNPExpress takes rs numbers as inputs. (Figure 1)

Figure 1

(2) Using navigation tree to further select nearby SNPs. (Figure 2)

Figure 2

(3) The selected SNP will be highlighted in the result panel. (Figure 3) P values generated from the 'cis-acting genetic regulation' screening will be displayed too.

Figure 3

(4) Once a gene is selected too, one then can elect to plot the expression levels by genotypes of the selected SNP, and test their associations. (Figure 4)

Figure 4

(5) The results for 'Expression by Genotype' function. (Figure 5) Rectangle in yellow indicates the examined expression is at transcript level, and green indicates exon probeset level.
