PG - 139-41 AB - We describe the identification of the novel human leukocyte antigen (HLA) blank allele A*2901102 N which was detected in an individual of mixed race. The serological HLA class I typing was A1; B7,44 whereas PCR-SSP indicated the presence of an additional A*29 allele. The pedigree analysis demonstrated that the new blank allele segregated with the haplotype A*29null B*07, inherited from the individual's Vietnamese father. A single G-->Tau transversion was detected at position 1 of intron 4, which is a highly conserved nucleotide position in vertebrate splice donor sites. Accordingly, it is very likely that this nucleotide exchange inhibits the splicing of intron 4, resulting in a premature stop codon further downstream. Despite this alteration, transcription into mRNA was demonstrated. FAU - Elsner, H-A AU - Elsner HA AD - Department of Transfusion Medicine, Hannover Medical School, Germany.
