MF-TOWmuT

MF-TOWmuT performs joint association testing of multiple phenotypes and genetic variants in family-based samples using an optimally weighted combination of common and rare variants to detect multivariate genetic associations.

Key Features:

• Joint Analysis Capability: Harnesses the correlation structure among multiple genetic variants and multiple phenotypes through a joint analysis framework.
• Optimally Weighted Combination: Employs an optimally weighted combination of both common and rare genetic variants to enhance association detection across the variant frequency spectrum.
• Applicability to Family Data: Designed for family-based samples to leverage familial correlations in association testing.
• Versatility Across Traits: Supports analysis of both qualitative and quantitative traits.
• Statistical Robustness: Maintains type I error control and demonstrates superior power in simulation studies compared to the Multiple Family-based Quasi-Likelihood Score Test and the Multivariate Family-based Rare Variant Association Test.

Scientific Applications:

• Multi-phenotype genetic association studies: Applicable to large-scale studies integrating multiple phenotypes influenced by a range of genetic variants.
• Complex disease genetics and familial analyses: Facilitates investigation of hereditary influences and gene-environment interactions using family data.

Methodology:

Performs joint analysis of multiple genetic variants and multiple phenotypes within genomic regions using family-based samples and optimizes variant weights to maximize detection power while preserving type I error, with performance evaluated by simulation studies.
