Abstract

Objective: To study the Mitochondrial DNA 7445A-->G mutation in nonsyndromic deafness patients in Chinese population.

Method: Polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) were used to screen the mitochondrial DNA 7445A-->G mutation among 128 nonsyndromic deafness individuals from 32 pedigrees, 135 sporadic nonsyndromic deafness patients and 100 normal subjects.

Result: The 7445A-->G mutation did not appear in the experiment.

Conclusion: Incidence of the mitochondrial 7445A-->G mutation was lower than that of mtDNA 1555A-->G mutation in nonsyndromic deafness patients in China.
