# How to interpret UniProt allele patterns?

In creating a parser for the UniProt flat file uniprot_sprot.dat (directory) in the manual for the comments POLYMORPHISM there are listed patterns for alleles, e.g. for 1A11_HUMAN is

The following alleles of A-11 are known:
A*11:01 (A-11E), A*11:02 (A-11K), A*11:03, A*11:04, A*11:05 and A*11:07.

I tried searching for a description of the patterns using the words allele and/or polymorphism and found nothing.

• How are the allele patterns to be interpreted?
• Is there a search term to be used when looking for the patterns?
• Also, is there an official repository of the alleles?

The answer does not have to explain the specifics of the example given.

Example of explanation of other allele pattern from here

This explanation of the patterns doesn't explain the part of the pattern in UniProt like (A-11E).

• Thanks. I gave it an up-vote, but I don't see how this answers my main question of How are the allele patterns to be interpreted? Also my background is in computer programming, so please don't take for granted I have knowledge on the bioinformatic information. :) Mar 19, 2019 at 14:14
