Abstract:
Objective: To investigate the distribution characteristics of Kidd blood group antigens, phenotypes and genotypes in Xinjiang and their influence on the risk of coronary heart disease. Methods: Samples from 7 981 patients treated at People's Hospital of Xinjiang Uygur Autonomous Region from August 1, 2023 to May 31, 2024 were collected for Jk(a-b-) phenotype screening via urea hemolysis test, followed by the third-generation sequencing (TGS). Kidd blood group Jk
and Jk
antigens in 1 081 patients with coronary heart disease and 1 021 healthy people were detected, and their phenotype frequency distribution was analyzed and corresponding gene frequencies were calculated. Correlation analysis and logistic regression were used to evaluate the influence of Kidd blood group antigen expression on coronary heart disease risk. Results: Two Jk(a-b-) phenotype samples were detected, both resulting from novel gene mutation combinations. Comparative analysis of two groups revealed a higher proportion of the Jk(a-b+) phenotype in the case group (22.5%, 243/1 081) than in the control group (18.5%, 189/1 021). Moreover, Kidd blood group phenotype distribution varied significantly across all ethnic groups in the case group (P<0.05). In the control group, the Hui ethnic group exhibited the highest JK
JK
genotype frequency 64.15% (34/53). In the case group, the highest JK
allele frequency was observed in Mongol ethnic group 56.31% (125/222), and the lowest in Han patients 45.71% (341/746). The expression of Jk
antigen was negatively correlated with coronary heart disease (P<0.05). Conclusion: The distribution of Kidd blood group system varied across ethnic groups in Xinjiang. The expression of Jk
antigen may have protective effect on coronary heart disease, which provides a basis for future clinical blood transfusion treatment and the mechanism study of the correlation between Kidd blood group and coronary heart disease.
