The sequencing-based typing tool of dbMHC: typing highly polymorphic gene sequences.

The dbMHC resource (http://www.ncbi.nlm.nih.gov/mhc/sbt.cgi?cmd=main) at the National Center for Biotechnology Information (NCBI) has developed an online tool for evaluating the allelic composition of sequencing-based typing (SBT) results of cDNA or genomic sequences. Whether the samples are heterozygous, haploid or a combination of the two, they can be compared with two up-to-date databases of all known alleles of several human leukocyte antigen (HLA) and killer cell immunoglobulin-like receptor (KIR) loci. The results of the submission are returned as a table of potential allele hits, along with the respective base changes and an interactive sequence viewer for close examination of the alignment.
