ABSTRACT
OBJECTIVE@#To study the clinical and sequence character of the entire mitochondrial genome in five subjects with mitochondrial 12SrRNA T1095C mutation, and to analyze its relationship with the military noise-induced hearing loss (NIHL).@*METHOD@#Three hundreds and four soldiers exposed to military noise were selected in Yunan and Beijing, including susceptible (experimental) and tolerance (control) groups. Mitochondrial 12SrRNA T1095C mutation were found in 5 subjects. Then the complete nucleotide sequence of five subjects were sequenced and its clinical character were analyzed.@*RESULT@#m12SrRNA T1095C mutation were identified in 5 subjects of experimental group,and none were found in control group. There was significant difference between them (P < 0.05). All five soldiers had the history of military noise exposure and showed sensorineural deafness of different degrees. Sequence analysis of the complete mitochondrial genomes showed the distinct sets of mtDNA polymorphism besides T1095C mutation in five subjects.@*CONCLUSION@#The T1095C mutation in hearing loss subjects with various genetic background and history of military noise exposure, is involved in the pathogenesis of hearing impairment. It indicates that the T1095C mutation do relate well with military noise induced-hearing loss.
