Background:

Human Leukocyte Antigen (HLA) matching is critical for kidney graft survival.
HLA-DQ matching shows preliminary importance for successful transplantation.

Purpose of the Study:

To develop a rapid and accurate method for HLA-DQA typing.
To facilitate improved donor-recipient matching in kidney transplantation.

Main Methods:

Developed a Polymerase Chain Reaction Sequence-Specific Primers (PCR-SSP) based method.
Utilized 18 specific primers for identifying known DQA1 alleles.
Procedure involves DNA isolation, PCR amplification, and UV visualization.

Main Results:

The method identified all currently known DQA1 alleles.

Typing a single individual requires 12 PCR mixes and takes approximately 3 hours.

Demonstrated high concordance with the RFLP method in 151 individuals, with only one discrepancy.

Conclusions:

The developed PCR-SSP method is a fast, reliable, and accurate tool for HLA-DQA typing.
This method is suitable for prospective cadaver donor typing.
Facilitates HLA-DQ matching to potentially enhance kidney transplant outcomes.
