Proteomics Solutions for Genetic Association Study

Hundreds of genetic variants are associated with complex disorders, but the underlying molecular pathways often remain elusive. Genome-wide association studies (GWAS) are powerful approaches to identify genes responsible for diseases. GWAS has identified thousands of loci associated with complex traits, but pinpointing the causal genes in these loci and underlying molecular pathways is a daunting task. Because the genomic data information of GWAS contains coding, non-coding, functional and non-functional genetic variants, it is difficult to distinguish them in association studies.

In contrast, proteomic analysis of biological samples such as cells, tissues, and body fluids has yielded valuable insights into the complex processes of disease in recent years. Proteins represent intermediate phenotypes of disease, and variability in protein sequence or abundance is directly linked to disease mechanisms and phenotypes. Genetic association studies at the protein level provide functional evidence to map disease associations and translate this knowledge into clinical applications.

Therefore, we expect to examine the relationship between disease-causing genes and phenotypic variation at the protein level to reveal disease-related pathways, new drug targets, and translational biomarkers.

With the upgrading of mass spectrometers, proteomics technologies, and the continuous development of analysis software and databases, genome-wide and population-scale analysis of proteomic data can be achieved.

Our Discovery Proteomics Service

Our Discovery Proteomics platform enables the identification and quantification of thousands of proteins and can screen out genetic association proteins.

The discovery proteomics platform uses DIA MS proteomics methods such as swath-MS, a massively parallel and highly reproducible protein quantification technique. This combining proteomics and genome-wide association studies (PWAS) technique can be used to identify proteins that bind specifically to alleles and assess the association between abundance distribution and phenotype of each quantified protein. Thus, support unraveling the molecular mechanisms by which SNPs may play a role in gene regulation.
