HLA Comparison

NOTICE: Experimental software

This software is still under development and has not been fully tested. Please let us know what you think at immuno@lanl.gov.

This tool takes two series of tab-delimited HLA types and compares the HLA frequencies in the two sets. For more information, see details below, and try Sample Input.

Details

HLA frequency

HLA frequences can be counted two different ways, which differ in how homozygous alleles are counted.

Population

Frequencies of HLA type per person. Homozygous HLAs are counted once.

Allele

Frequencies of HLA type per allele. Homozygous HLAs are counted twice.

HLA 2/4 digit conversion

HLA type are reported with various resolutions (2, 4 or more digits). This tools provied three options for handling this.

Leave HLAs as presented

The HLA type are left unchanged and each distinct type is counted seperately.

4-digit HLA comparison

Silent mutations are ignored; HLA types with more than 4 digits precision are truncated. HLA type with 2 digits are left unchanged.

2-digit HLA comparison

All HLA type are converted to 2 digits. The conversion serotype information if available or else the 2-digit HLA family.
