A novel HLA-B*35 (B*3570) allele of a Caucasian family differing with one amino acid mismatch from HLA-B*3503 allele in exon 4.

A novel human leucocyte antigen (HLA)-B35 (HLA-B*3570) allele has been identified in a Caucasian family from Middle Europe using single allele-specific sequencing strategy. This allele is identical to the HLA-B*3503 allele except for one point mutation in exon 4 at codon 188 (CAC-->CGC), resulting in an amino acid change from histidine to arginine.
