Genetic resonance: dissecting the heritability and genetic correlations of human hearing acuity.

ABSTRACT: This study presents a frequency-specific, pedigree-based assessment of hearing acuity heritability. We analysed 34 Utah Centre d'Etude du Polymorphisme Humain (CEPH) pedigrees comprising 464 individuals, using whole-genome sequencing (WGS) and audiometric evaluations. Our analysis reveals a general decline in narrow-sense heritability as frequency increases. When calculated using the Sequential Oligogenic Linkage Analysis Routines (SOLAR) software package, narrow-sense heritability estimates drop from 51% at 250 Hz to 30% at 8000 Hz. Genetic correlations (Rho(G)), the degree to which genetic variation in one trait correlates with another, are higher for hearing acuity at similar frequencies. For example, Rho(G) between 250 and 500 Hz is 0.80, and Rho(G) between 6000 and 8000 Hz is 0.91. In
