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.

Human milk is important for infant development, but few large studies have comprehensively investigated milk composition. Here, we characterized human milk oligosaccharides (HMOs) and milk microbiota, their shaping factors, and their links to infant gut microbiota in the longitudinal Dutch Lifelines NEXT cohort. We measured 24 HMOs in 1,542 milk samples from 524 mothers at 0.

We report the largest genome-wide association study meta-analysis in ankylosing spondylitis (AS) to date (25,645 cases, 71,224 controls), identifying 27 novel loci and 86 independent genetic associations. Variations in (non-secretor status) and (blood group A) increase AS risk, with Mendelian randomisation (MR) linking non-secretor status to increased AS risk from reduced gut carriage of . Associations with three telomerase maintenance genes (, ), and MR analysis, suggest increased telomere length causally increases AS susceptibility.

Objective: We investigated if specific carbohydrate blood group antigens were associated with infant botulism (IB) among discordant twins and triplets.
Study Design: Infants in the US and Canada from 2015 to 2022 who had laboratory-confirmed IB; were members of a multiple gestation birth; and had unaffected sibling(s), were eligible to participate. Blood specimens were tested for ABO, Lewis, H, and P1 carbohydrate blood antigens.

Background: The para-Bombay phenotype is a rare red blood cell phenotype characterized by the absence or reduction of ABH antigens on red blood cells but the presence of ABH substances in saliva.
Materials And Methods: Red blood cells were phenotyped by standard serology methods. The CDS region of ABO, FUT1, and FUT2 was amplified with polymerase chain reaction and then directly sequenced.

Background: Integration of precision diagnosis in Immunohaematology and Transfusion Medicine has led to the development of more refined blood typing and crossmatching techniques, ensuring improved accuracy of blood group determination, thereby reducing the incidence of transfusion reactions and enhancing patient safety. It can also help resolve complex discrepancies noted in serological testing methods.
Study Design And Methods: The blood grouping of a 40 year old female patient done as a part of routine health check using column agglutination technology showed a O group phenotype with additional reaction with O cells in the serum group.
