A novel HLA-Cw*15 allele, Cw*1510, found in a French Caucasian bone marrow
recipient is described. Nucleotide sequence of the new variant is identical
to the common Cw*15021 DNA sequences except nucleotides at positions 32 an
d 61 of exon 2. While the first difference is silent, the second cause subs
titution of an Histidine by an Arginine at amino acid position 21 of the al
pha1 heavy chain domain.
