A novel TaqI/DQA RFLP associated with HLA-DR9, DQ9 (DQA1*0302).
A new TaqI/DQA restriction fragment length polymorphism (RFLP) has been found in two Spanish Caucasoid individuals. The novel polymorphic fragment has a relative mobility of 4.2 kb and is associated with an HLA-A2,Cw*1401,B51,DR9,DR53,DQ9 haplotype. Nucleotide sequence analysis indicates that individuals showing this RFLP pattern do not carry a new DQA1 allele, but that (DQA1*0302) commonly observed in DR9,DQ9 haplotypes. The new RFLP seems to be a locally restricted marker of uncertain origin.
