Abstract

fetched live from OpenAlex

Age-related hearing loss affects one-third of the population over 65 years. However, the diverse pathologies underlying these heterogeneous phenotypes complicate genetic studies. Here we show that by applying computational phenotyping approaches based on audiometrically measured hearing loss, we can overcome challenges associated with accurate phenotyping for older adults with hearing loss. Using this phenotyping strategy, we uncover differences in the associations observed between genetic variants and sensory and metabolic hearing loss. Sex-stratified analyses of these sexually dimorphic hearing loss phenotypes reveal a locus of relevance to sensory hearing loss in males, but not females. Enrichment analyses implicate genes involved in frontotemporal dementia in metabolic hearing loss, while genes relating to sensory processing of sound by hair cells are implicated in sensory hearing loss. Our study enhances our understanding of these two hearing loss phenotypes, representing the first step in the development of more precise treatments for these pathologically distinct hearing loss phenotypes.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
