When integrating multi-omics data, what is the primary computational step required to synchronize variant calls and gene expression data to ensure that expression quantitative trait loci (eQTL) are accurately mapped to the correct regulatory elements?

The primary computational step required to synchronize variant calls and gene expression data is sample ID harmonization, which is the process of verifying and mapping biological identifiers across disparate datasets to ensure that the genotype of a specific individual corresponds exactly to the expression profile of that same individual. Variant calls represent the identified genetic differences at specific locations in a genome, while ....
