H12 / Guinea An. gambiae / Chromosome X / #1

This page describes a signal of selection found in the Guinea An. gambiae population using the H12 (Garud et al. 20XX) statistic.The focus of this signal is on chromosome arm X between positions 14,960,001 and 15,100,000. 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 5 genes overlap the focal region: AGAP000817, AGAP000816, AGAP013474, AGAP013173, AGAP013424.

The following 3 genes are within 50 kbp of the focal region: AGAP0008131 (Frataxin homolog, mitochondrial), AGAP000814, AGAP000815 (INTB - integrin beta subunit).

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