IHS/CMS/2/6

This page describes a signal of selection found in the Cameroon An. gambiae populationusing the IHS (Cite et al. 20XX) statistic.The focus of this signal is on chromosome arm 2L between positions 42,394,895 and 42,434,895. The evidence supporting this signal is weak (\Delta_{i} < 50 on one or 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 3 genes overlap the focal region: AGAP0070862 (Sodium channel protein), AGAP007088 (peptidyl-prolyl cis-trans isomerase B (cyclophilin B)), AGAP007089.

The following 2 genes are within 50 kbp of the focal region: AGAP007087 (RpL41 - 60s ribosomal protein L41), AGAP007090.

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