Abstract:
We describe a new DPB1 allele, DPB1*8501, which was identified by sequencing-based typing (SBT) in the UCLA exchange. DPB1*8501 is similar to DPB1*2701 with a difference at position 272, (G to A). This difference leads to an amino-acid change of codon 91 from arginine (CGC) to histidine (CAC). Until now this position has been considered conserved. This substitution is located at the 3' site of exon 2, and may interfere with typing strategies using primers or probes located in this region.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
