XPEHH/UGS.GWA/2/3

This page describes a signal of selection found in the Uganda An. gambiae population when compared with the Guinea Bissau population using the XPEHH (Cite et al. 20XX) statistic.The focus of this signal is on chromosome arm 2R between positions 50,960,000 and 51,100,000. 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 9 genes overlap the focal region: AGAP004160, AGAP004161 (myofilin variant C), AGAP004162 (myosin, light polypeptide 9, regulatory), AGAP0041631 (GSTD7 - glutathione S-transferase delta class 7), AGAP0041641 (GSTD1-4 - glutathione S-transferase delta class 1), AGAP0041651 (GSTD2 - glutathione S-transferase delta class 2), AGAP004166, AGAP004167, AGAP004169.

The following 4 genes are within 50 kbp of the focal region: AGAP004156 (synaptic vesicle protein), AGAP004157 (synaptic vesicle protein), AGAP004158 (UDP-sugar diphosphatase), AGAP0041591 (malate dehydrogenase (oxaloacetate-decarboxylating)(NADP )).

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