IR gene name and phylogenetic branch showing positive selection is reported in the first two columns. Values obtained from HyPhy for positive selection are shown only for the IR genes supported by a significant p-value obtained from the likelihood ratio test (LRT) and corrected for multiple testing with the Holm formula
