Abstract excerpt

OBJECTIVE: To study the correlation between the number of mtDNA (mitochondrial DNA) copies containing mtDNA A1555G mutation site and phenotype and further elucidate the molecular genetic basis of phenotype diversity of nonsyndromic hearing loss. METHODS: Real time-amplification refractory mutation system-quantitative PCR was employed to detect the number of mtDNA copies in mild type and mutant type of mtDNA 1555....
