Abstract excerpt

OBJECTIVE: To investigate the prevalence of the mitochondrial DNA (mtDNA) A1555G mutation in nonsyndromic hearing impairment (NSHI) patients from Gansu province. METHODS: Subjects included 802 students selected from five Deaf-Mute Schools in Gansu. DNA was extracted from peripheral blood of all patients. The mitochondrial DNA target fragments were amplified by polymerase chain reaction (PCR). The Mutations were...
