H12 / Burkina Faso An. gambiae / Chromosome 2 / #1

This page describes a signal of selection found in the Burkina Faso An. gambiae population using the H12 (Garud et al. 20XX) statistic.The focus of this signal is on chromosome arm 2L between positions 2,420,001 and 2,720,000. 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 13 genes overlap the focal region: AGAP0047072 (para - voltage-gated sodium channel), AGAP004708 (arginyl-tRNA synthetase), AGAP004709 (mRpL18 - 39S ribosomal protein L18, mitochondrial), AGAP0047101 (ubiquinol-cytochrome c reductase subunit 9), AGAP004711 (ATP-dependent RNA helicase DDX41), AGAP004712, AGAP004713, AGAP004714, AGAP0047151 (Pyruvate dehydrogenase phosphatase regulatory subunit, mitochondrial), AGAP0047163 (Gr57 - gustatory receptor 57), AGAP004717, AGAP004718, AGAP004719 (CLIPC9 - CLIP-domain serine protease).

The following 4 genes are within 50 kbp of the focal region: AGAP004720, AGAP004721 (N-acetylglucosamine-6-sulfatase), AGAP004722, AGAP004723 (chromobox protein homolog 1).
