XPEHH/GWA.BFS/2/3

This page describes a signal of selection found in the Guinea Bissau 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 2R between positions 47,760,000 and 47,800,000. 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

Gene AGAP004000 (myosin IX) overlaps the focal region.

The following 11 genes are within 50 kbp of the focal region: AGAP003997 (casein kinase 1, gamma), AGAP003999, AGAP004002 (60 kDa heat shock protein, mitochondrial precursor), AGAP013015 (p53 and DNA damage-regulated protein), AGAP004003, AGAP004004, AGAP004005, AGAP013019, AGAP004006, AGAP004007, AGAP004008.

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