Aim: To investigate the polymorphism of DQCAR alleles and their association with HLA-DRB1, -DQA1, -DQB1 haplotypic associations in the Croatian population.
Methods: Blood samples were collected from 135 healthy unrelated donors from Zagreb area previously typed for HLA class II alleles (DRB1, DQA1, DQB1). The DQCAR samples were run on a standard denaturing sequencing gel in a DNA sequencer and the sequences were analyzed and compared.
