Non-Mendelian mitochondrial inheritance as a cause of progressive genetic sensorineural hearing loss.

Abstract excerpt

Awareness of non-Mendelian mitochondrial inheritance and of its role as an agent of genetic sensorineural hearing loss (SNHL) is recent. Mitochondria are passed on exclusively from the ovum to all the offspring of both sexes, a novel pattern of inheritance. Owing to the critical role of mitochondria in cellular energy metabolism, deletions or point mutations of the mitochondrial DNA often cause progressive SNHL...
