Figure 1. DNA polymorphisms within HLA-A promoter and exon 1 sequences.

Figure 1

A 1000-bp region (Panel a) has been sequenced for select population samples. Upper case letters are cDNA sequences (part of the open reading frame); the translation start codon (ATG) is indicated by a horizontal arrow. STR denotes a short tandem repeat sequence that has either three or four AAC repeats. Five transcription factor-bindings sites (TFBS) are also indicated. Within this fragment, 69 single nucleotide polymorphisms (SNPs) (bold and underlined) have already been reported in the literature. Those (n = 19) not confirmed in this work are shaded grey. The five novel SNPs are designated as “New” (underlined nucleotides below vertical lines). The SNPs unique to A*3201 are marked by vertical arrows before their respective reference sequence (rs) numbers (from dbSNP database, version 126). In panel b, 53 informative SNPs (minor allele frequency ≥0.02) are linked to 11 HLA alleles found in homozygous state.
