XPEHH/AOM.BFM/2/7

This page describes a signal of selection found in the Angola An. coluzzii population when compared with the Burkina Faso An. coluzzii population using the XPEHH (Cite et al. 20XX) statistic.The focus of this signal is on chromosome arm 2R between positions 34,320,000 and 34,440,000. 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 7 genes overlap the focal region: AGAP003238 (N-myc downstream regulated), AGAP003239 (meiotic chromosome segregation protein), AGAP003240 (Protein jagunal), AGAP003241, AGAP003242 (RNA polymerase-associated protein LEO1), AGAP003243, AGAP003244 (GPRGHP2 - putative growth hormone releasing hormone receptor 2).

The following 15 genes are within 50 kbp of the focal region: AGAP003235 (lachesin), AGAP003236, AGAP003237 (tubulin, alpha 1), AGAP003245 (CLIPA19 - CLIP-domain serine protease), AGAP003246 (CLIPB2 - CLIP-domain serine protease), AGAP003247 (CLIPB19 - CLIP-domain serine protease), AGAP003248, AGAP013487, AGAP003249 (CLIPB3 - CLIP-domain serine protease), AGAP003250 (CLIPB4 - CLIP-domain serine protease), AGAP003251 (CLIPB1 - CLIP-domain serine protease), AGAP003252 (CLIPB6 - CLIP-domain serine protease), AGAP013184 (CLIPB36 - CLIP-domain serine protease), AGAP003253 (Gr15 - gustatory receptor 15), AGAP003254 (Gr16 - gustatory receptor 16).

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