Detection of HLA polymorphisms by ligase detection reaction and a universal array format: A pilot study for low resolution genotyping

We present our results in the identification of polymorphic sites within the second exon of the human leukocyte antigen A (HLA-A) region using the DNA microarray technology. Allele specific detection was performed by polymerase chain reaction followed by ligase detection reaction (LDR) in combination with a universal array, a powerful method for high throughput DNA sequence analysis. By this approach we confirmed 32 human samples previously characterized by direct DNA sequencing, thus demonstrating the interest of this approach.
