The HLA class II region sequences included in this compilation are tak
en from publications listed in the papers: Nomenclature for factors of
the KLA system, 1994 (Bodmer et al., 1994), Nomenclature for factors
of the HLA system, 1991 (Bodmer et nl., 1992), Nomenclature for factor
s of the HLA system, 1990 (Bodmer ct al., 1991) and Nomenclature for f
actors of the HLA system, 1989 (Bodmer el al., 1990). Where discrepanc
ies have arisen between reported sequences, the original authors have
been contacted where possible, and necessary amendments to published s
equences have been incorporated into this alignment. Future sequencing
may identify errors in this list and we would welcome any evidence th
at helps to maintain the accuracy of this compilation. fn the sequence
alignments, identity between residues is indicated by a hyphen (-). A
n unavailable sequence is indicated by an asterisk (), gaps in the se
quence are inserted to maintain the alignment between different allele
s showing variation in amino acid number. In the following Tables, all
ele alignments include sequences across all exons. However, since for
many alleles sequence information is incomplete, such alleles will be
cut short in the Tables and the alignments compressed to conserve spac
e.
