IHS/BFS/3/6

This page describes a signal of selection found in the Burkina Faso An. gambiae populationusing the IHS (Cite et al. 20XX) statistic.The focus of this signal is on chromosome arm 3L between positions 26,919,316 and 26,959,316. The evidence supporting this signal is strong (\Delta_{i} >= 100 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 6 genes overlap the focal region: AGAP011537 (Argonaute 3), AGAP028430, AGAP011538, AGAP011539 (dynein intermediate chain 2, axonemal), AGAP011540 (dynein intermediate chain 2, axonemal), AGAP011541 (Ecto-NOX disulfide-thiol exchanger 1).

The following 7 genes are within 50 kbp of the focal region: AGAP011531 (Selenium-binding protein 2), AGAP011532 (septin), AGAP011533 (tetratricopeptide repeat protein 15), AGAP011534, AGAP011535 (transcription elongation factor B, polypeptide 1), AGAP011536 (Mini-chromosome maintenance complex-binding protein), AGAP011542.

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