OBJECTIVES: Associations of ABO blood group specifying transferases A/B (ABO) and fucosyltransferase 2 (FUT2) with CP remain inconclusive. We aimed to comprehensively investigate the associations by Chinese sequencing cohorts and external cohorts.
METHODS: First, we analyzed the distributions of ABO blood groups and FUT2 status, along with lead single nucleotide polymorphisms (SNPs) at ABO (rs8176693 C/T) and FUT2 (rs632111 A/G) gene loci in Chinese low-coverage whole-genome sequencing discovery cohort. Subsequently, we investigated the associations of CP with ABO and FUT2 SNPs in Chinese whole-exome sequencing validation cohort and three public biobanks (FinnGen, UK Biobank, and BioBank Japan). Finally, comprehensive meta-analysis was performed by integrating data from two Chinese cohorts, reported cohorts and public biobanks.
RESULTS: Firstly, in Chinese discovery cohort, the distribution of blood types in CP patients showed no significant difference compared to healthy controls, and similar results were observed in subgroup analyses and in meta-analysis with the reported cohorts. Secondly, results indicated no association between rs8176693 or rs632111 and CP in Chinese cohorts and meta-analysis of three biobanks, though ABO SNP was found to be significantly associated with CP in UK Biobank (odds ratio [OR] = 1.27, P = 0.04). Finally, no association was observed between rs8176693 (OR = 1.03, P = 0.29) or rs632111 (OR = 1.04, P = 0.10) and CP in comprehensive meta-analysis.
CONCLUSIONS: No association was found between lead SNPs of ABO or FUT2 and CP in meta-analysis, nor was there an association between ABO blood group or FUT2 secretor status and CP in Chinese cohort. ABO and FUT2 might play limited role in CP development.
