MUGO: Differentiable Combinatorial Optimization for Causal Variant Discovery in the Non-coding Genome

MUGO (Multi-head Genomic Optimization), an in silico perturbation framework that casts variant discovery as differentiable combinatorial optimization over genomic sequence, and MUGO-prioritized variants are enriched for GWAS signals across diverse tissues and a broad spectrum of complex traits.

High sperm DNA fragmentation is associated with increased embryonic chromosomal abnormality: a retrospective study of 8 years involving 5637 couples undergoing ART

Does sperm DNA fragmentation impair blastocyst chromosomal integrity? A high sperm DNA fragmentation index (DFI) is associated with an increased risk of blastocyst aneuploidy, particularly when the man has poor semen quality or when the female partner is aged ≥35 years. Evidence linking sperm DFI to...

MUGO: Differentiable Combinatorial Optimization for Causal Variant Discovery in the Non-coding Genome

Deciphering how non-coding variants perturb gene regulation is central to translating GWAS loci into mechanism, yet existing prioritization methods rarely deliver cell-type-resolved molecular effects, causal variant-to-gene attribution, or principled reasoning about combinatorial interactions. We introduce MUGO (Multi-...
