IHS/BFM/3/1

This page describes a signal of selection found in the Burkina Faso An. coluzzii populationusing the IHS (Cite et al. 20XX) statistic.The focus of this signal is on chromosome arm 3R between positions 28,260,000 and 28,620,000. The evidence supporting this signal is strong (\Delta_{i} >= 100 on both flanks).

This signal overlaps the Gste locus, a genome region with prior evidence of an association with insecticide resistance and/or recent positive selection in Anopheles mosquitoes.

Signal location. Blue markers show the values of the selection statistic. The dashed black line shows the fitted peak model. The shaded red area shows the focus of the selection signal. The shaded blue area shows the genomic region in linkage with the selection event. Use the mouse wheel or the controls at the top right of the plot to zoom in, and hover over genes to see gene names and descriptions.

Genes

The following 17 genes overlap the focal region: AGAP009183 (defective proboscis extension response), AGAP009184, AGAP009185, AGAP0091871 (Indanol dehydrogenase), AGAP009188 (solute carrier family 39 (zinc transporter), member 9), AGAP009189, AGAP0091901 (GSTE8 - glutathione S-transferase epsilon class 8), AGAP0091911 (GSTE6 - glutathione S-transferase epsilon class 6), AGAP0091921 (GSTE5 - glutathione S-transferase epsilon class 5), AGAP0091931 (GSTE4 - glutathione S-transferase epsilon class 4), AGAP0091941 (GSTE2 - glutathione S-transferase epsilon class 2), AGAP0091951 (GSTE1 - glutathione S-transferase epsilon class 1), AGAP0091961 (GSTE7 - glutathione S-transferase epsilon class 7), AGAP0091971 (GSTE3 - glutathione S-transferase epsilon class 3), AGAP009198, AGAP009199 (palmitoyltransferase ZDHHC24), AGAP009200 (collagen type IV alpha).

The following 5 genes are within 50 kbp of the focal region: AGAP009182 (protein transport protein SEC61 subunit alpha), AGAP009201 (collagen type IV alpha), AGAP009202 (selenoprotein T), AGAP028058, AGAP009203 (SPRY domain-containing SOCS box protein 3).

Key to insecticide resistance candidate gene types: 1 metabolic; 2 target-site; 3 behavioural; 4 cuticular.
