What it means

A new metric called (Gene Identity Score of ) quantifies how frequently a gene has been lost across 462 mammalian species, allowing researchers to distinguish essential genes (rarely lost) from dispensable ones. The study, published in Nature Genetics, also introduces for and uses evolutionary signal to infer human gene function and disease relevance.

Accuracy & sourcesGrounded

This is the primary research paper itself, published in Nature Genetics with a verified DOI. The claims are directly from the peer-reviewed study, so accuracy is high. The search results corroborate the details of the methodology and findings.
