XPEHH/UGS.BFS/3/5

This page describes a signal of selection found in the Uganda An. gambiae population when compared with the Burkina Faso An. gambiae population using the XPEHH (Cite et al. 20XX) statistic.The focus of this signal is on chromosome arm 3R between positions 49,540,000 and 49,660,000. The evidence supporting this signal is moderate (\Delta_{i} >= 50 on both flanks).

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 5 genes overlap the focal region: AGAP013739, AGAP010156 (ATP citrate lyase), AGAP013762, AGAP010157 (Ast2 - allatostatin 2), AGAP010158.

The following 8 genes are within 50 kbp of the focal region: AGAP010149 (cytochrome b5-related), AGAP0101501 (cytochrome b5-related), AGAP010151, AGAP010152 (gem associated protein 5), AGAP010155, AGAP010159 (dUTP pyrophosphatase), AGAP010160 (myosin I), AGAP010161.

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