You can add best matching genotype by navigating to the HLA Typing sample result screen and selecting “Add genotype” from the right click context menu. Browse the displayed P and G groups to locate the allele pair candidate that you wish to add. Please note that the already present result cannot be added again.
If you are in the Genome Browser you can add alleles by selecting “Add custom allele(s) to 1st/2nd chromosome” from the right click context menu. Note that if you choose this option then your selected alleles won’t be permanently attached to the sample. If you would like to convert the alleles that you added into a custom genotype please select “Convert custom allele pair to result genotype” from the right click context menu.
