A 356-Kb Sequence of the Subtelomeric Part of the MHC Class I Region

Abstract

The subtelomeric part of the MHC Class I region contains 11 of the 21 genes described on chromosome 6 at position 6p21.3. The general organization of those and other genes resident in the region was revealed by determining a 356,376 bp sequence. Potential exons for new genes were identified by computer analysis and a large number of ESTs were selected by testing the sequence by the BLAST algorithm against the GenBank nonredundant and EST databases. Most of the ESTs are clustered in two regions. In contrast, the whole HLA-gene region is crammed with LINE and SINE repeats, fragments of genes and microsatellites, which tends to hinder the identification of new genes.
