Polygenic inheritance of sensorineural hearing loss (Snhl2, -3, and -4) and organ of Corti patterning defect in the ALR/LtJ mouse strain

► ALR/LtJ mice exhibit profound sensorineural hearing loss. ► Hearing loss in ALR/LtJ mice is controlled by three quantitative trait loci. ► Extra rows of outer hair cells accompany hearing loss.
