I'm interested in HLA imputation results from UK biobank (which was created by HLA*IMP 2 algorithm) and I have registered to have the access of HLA imputation values (field 22182 https://biobank.ctsu.ox.ac.uk/crystal/field.cgi?id=22182 ). However, these values are not annotated and I am unable to interpret results despite a bunch of values just like example data (https://biobank.ctsu.ox.ac.uk/crystal/examples/eg_hla_impute.dat ).

Have anyone analyzed HLA imputation values from UK biobank before? How do you interpret the results (and if possible, how to compare HLA allele frequency in interested phenotype, is chi-square with FDR adjustment enough). Any suggestion is appreciated.

I have the same issue.

Field 22181 contains Q2 values of HLA:IMP*02 output. 362 values for each individual (separated by commas) is available and each value represents the probability of a given allele. However, there is no information in the downloaded data, which of the 362 values refer to which allele.

I have already written to UK Biobank, the programmer of HLA:IMP*02 and the authors, who contributed to HLA genotyping, but have received no answer yet. Have you had any handy solution in the previous two months?
