Abstract excerpt
Mitochondrial 12S rRNA and tRNASer(UCN) genes are the hot spots for mutations associated with hearing loss. We reported here the clinical, genetic and molecular analysis of a Chinese pedigree with maternally inherited sensorineural hearing loss. Molecular analysis showed that the pedigree carried both mitochondrial DNA (mtDNA) A1555G and G7444A mutations. The penetrance of hearing loss in this pedigree was 58%...
