HLA-DQA1 and -DQB1 allele typing in southern Taiwanese women with breast cancer.

Abstract

BACKGROUND:

The pathogenesis of breast cancer is multifactorial. Genetic predisposition, environmental factors, hormones and even infection agents are thought to interact in the manifestation of breast cancer. In particular, human leukocyte antigen (HLA) alleles play a pivotal role in cellular immunity and may be an important genetically determined host trait. Regardless of the importance and functions of HLA genes in the evolution of cancer, the allele-specific association of HLA molecules in cancer patients has not been well established. Recently, a few studies have concentrated on the association between HLA and breast cancer, but the results of these studies are controversial.

METHODS:

We designed a study to evaluate the association between the genotype of HLA class II genes and breast cancer. HLA-DQA1 and -DQB1 polymorphisms were determined by PCR with sequence-specific primers (PCR-SSP) in 101 Taiwanese women patients with breast cancer and 115 matched control subjects.

RESULTS:

Using PCR-SSP typing, HLA-DQA1 and -DQB1 locus comparison of allele frequencies between breast cancer patients and healthy controls showed no significant difference.

CONCLUSIONS:

We have established a significant lack of HLA-DQA1 and -DQB1 association with breast cancer in southern Taiwanese women. The results of this study may provide information for further clarification of the etiology of breast cancer in this region.
