Abstract: Genome-wide association studies with an Illumina Bovine50K chip have detected 105 SNPs associated with one or multiple milk production traits in the Chinese Holstein population. Of these, 38 significant SNPs detected with high confidence by both L1-TDT and MMRA methods were selected to further mine potential key genes affecting milk yield and milk composition. By blasting the flanking sequences of these 38 SNPs with the bovine genome sequence combined with comparative genomics analysis, 26 genes were found to contain or be near to such SNPs. Among them, the gene is merely 87 bp away from the significant SNP, Hapmap30383-BTC-005848. Hence, we report herein genotype-phenotype associations to further validate the genetic effects of the gene. By pooled DNA sequencing of 14 unrelated Holstein sires, a total of 18 with seven novel SNPs were identified. Among them, nine SNPs were in the 5′ regulatory region, one in exon 6 and the other in the 3′ UTR and 3′ regulatory region. A total of nine of these identified SNPs were successfully genotyped and analyzed by mass spectrometry for association with five milk production traits in an independent resource population. The results showed that these SNPs were statistically significant for more than two traits [ <(0.0001-0.0267)]. In addition, mRNA expression analyses revealed that was ubiquitous in eight different tissues, with a relatively higher expression level in the mammary gland than in other tissues. These findings, therefore, provide strong evidence for association of variants with milk yield and milk composition traits and may be applied in Chinese Holstein breeding programs.

Abstract:

Genome-wide association studies (GWAS) have achieved great success in identifying genetic variantsRecently, GWAS is quite the fashion in China.Enormous work needs to be done in the post-GWAS era.Along with pharmacogenomics, the success of GWAS in identifying genetic risk factors and genetic differences) as an example to demonstrate some of the inherent limitations and summarized future challenges of GWAS

A genome-wide association study of five meat quality traits in Yorkshire pigs

Qian DONG,Huiying LIU,Xinyun LI,Wei WEI,Shuhong ZHAO,Jianhua CAO

Frontiers of Agricultural Science and Engineering 2014, Volume 1, Issue 2,   Pages 137-143 doi: 10.15302/J-FASE-2014014

Abstract: Meat quality is an important trait in the pig industry. To identify genomic regions and haplotype blocks responsible for meat quality traits in pigs, a genome-wide association study was conducted for five traits including intramuscular fat content, pH at 45 min and 24 h, drip loss within 24 h and water-holding capacity in 231 Yorkshire barrows using illumina porcine 60k SNP chips. The results showed that a total of 344 single nucleotide polymorphisms (SNP) were significantly associated with five meat quality traits ( <1×10 ). Moreover, 323 SNPs were within the reported QTL regions, of which 21 were novel. Also, 158 SNPs fell into the proximal region of meat quality related genes. In addition, 25 haplotype blocks based on 116 SNPs were revealed with SNP combination patterns for five traits. Our study added new SNP information for identification of meat quality traits in pigs and will help elucidate the mechanisms of meat quality in pigs.

Twelve Years of Genome-Wide Association Studies of Human Protein N-Glycosylation Review

Anna Timoshchuk, Sodbo Sharapov, Yurii S. Aulchenko

Engineering 2023, Volume 26, Issue 7,   Pages 17-31 doi: 10.1016/j.eng.2023.03.013

Abstract:

Most human-secreted and membrane-bound proteins have covalently attached oligosaccharide chains, or glycans. Glycosylation influences the physical and chemical properties of proteins, as well as their biological functions. Unsurprisingly, alterations in protein glycosylation have been implicated in a growing number of human diseases, and glycans are increasingly being considered as potential therapeutic targets, an essential part of therapeutics, and biomarkers. Although glycosylation pathways are biochemically well-studied, little is known about the networks of genes that guide the cell- and tissue-specific regulation of these biochemical reactions in humans in vivo. The lack of a detailed understanding of the mechanisms regulating glycome variation and linking the glycome to human health and disease is slowing progress in clinical applications of human glycobiology. Two of the tools that can provide much sought-after knowledge of human in vivo glycobiology are human genetics and genomics, which offer a powerful data-driven agnostic approach for dissecting the biology of complex traits. This review summarizes the current state of human populational glycogenomics. In Section 1, we provide a brief overview of the N-glycan's structural organization, and in Section 2, we give a description of the major blood plasma glycoproteins. Next, in Section 3, we summarize, systemize, and generalize the results from current N-glycosylation genome-wide association studies (GWASs) that provide novel knowledge of the genetic regulation of the populational variation of glycosylation. Until now, such studies have been limited to an analysis of the human blood plasma N-glycome and the N-glycosylation of immunoglobulin G and transferrin. While these three glycomes make up a rather limited set compared with the enormous multitude of glycomes of different tissues and glycoproteins, the study of these three does allow for powerful analysis and generalization. Finally, in Section 4, we turn to genes in the established loci, paying particular attention to genes with strong support in Section 5. At the end of the review, in Sections 6 and 7, we describe special cases of interest in light of new discoveries, focusing on possible mechanisms of action and biological targets of genetic variation that have been implicated in human protein N-glycosylation.
