title: Sequence analysis of a new HLA-DR11 allele in a Caucasian Italian family: DRB1*11272.
abstract: This communication describes a new DRB1*11 allele identified in a familial group of Caucasian individuals from central Italy. The new sequence has been officially named DRB1*11272 by the World Health Organization (WHO) Nomenclature Committee (February 2000). It encodes an HLA antigen serologically recognized as DR11. The sequence variation of this new allele was localized to codon 77 of exon 2. It differs at position 230 from DRB1*11011 allele (A replacing C), and at position 231 from DRB1*1127 (C replacing T). At the amino acid level, the DRB1*11272 mutation is silent with respect to the DRB*1127 phenotype, coding for a synonymous asparagine.
