  1. ND: the nucelotidic sequence of this allele corresponds to an HLA gene but is not deposited in the IMGT/HLA alleles database (http://www.ebi.ac.uk/ipd/imgt/hla/). (a, b, c, d): Both peptides (a) and (b) are components of nine different MHC-I proteins. In our samples, from 1 to 9 of these different MHC-I proteins can be present. Both peptides (c) and (d) are components of five different MHC-I proteins. In our sample, from 1 to 5 of these different MHC-I proteins can be present.
  2. NM-organelles 1 and NM-organelles 2 were prepared from two different individuals. NM isolated from SN tissues was isolated from a pool of SN samples obtained from five individuals. Another NM sample was isolated from NM organelles prepared from one individual. For each peptide the corresponding gene(s) and the number of different alleles that may encode the peptide is reported.
  3. *MICA is an HLA related gene.
