Background:

Expression quantitative trait loci (eQTLs) are crucial for interpreting disease-associated genetic variation.
Single-cell RNA sequencing (scRNA-seq) data enables identification of cell-type-specific eQTLs.
Limited sample sizes in scRNA-seq hinder the discovery of cell-type-specific eQTLs.

Purpose of the Study:

To improve the power for detecting cell-type-specific eQTLs through large-scale joint analyses.
To address privacy constraints and technical variability across scRNA-seq datasets.
To propose and evaluate a federated weighted meta-analysis (WMA) approach for integrating scRNA-seq data.

Main Methods:

Comparison of different strategies for federated weighted meta-analysis (WMA).
Integration of summary statistics from diverse scRNA-seq datasets using dataset-specific weights.
Development of best practice recommendations for eQTL WMA.

Main Results:

Federated WMA effectively integrates data from multiple scRNA-seq studies.
The proposed approach enhances the detection power for cell-type-specific eQTLs.
Identified optimal strategies for robust eQTL WMA across heterogeneous datasets.

Conclusions:

Federated WMA is a viable solution for overcoming privacy and data heterogeneity challenges in scRNA-seq eQTL studies.
This method significantly improves the discovery of cell-type-specific eQTLs.
Provides practical recommendations for implementing eQTL WMA in large-scale scRNA-seq analyses.
