A study introduces genome-wide LD scores as a method for estimating heritability and genetic correlation across multiple distinct ancestral populations.

"Genome-wide LD scores enable multi-ancestry heritability estimation" — bioRxiv (Genomics) · Science & Medicine

What it means

This bioRxiv preprint introduces a method using genome-wide linkage disequilibrium (LD) scores to estimate and across multiple ancestral populations, overcoming the limitation of existing LD score regression (LDSC) methods that are typically ancestry-specific. It provides a framework for analyzing diverse GWAS summary statistics, enabling more inclusive genetic studies.

Accuracy & sourcesGrounded

The claim is based directly on the bioRxiv preprint, which is the primary source. The preprint describes the method and likely includes validation analyses, but the specific results and robustness are not immediately verifiable from the headline and note alone.

How new

The preprint was published on bioRxiv on 2026-10-22, making it genuinely new as of this writing.
