[Audiological and genetic studies on 130 infants with hearing loss].

Objective: To investigate the genetic etiologies in the 0- 3-years-old infants with hearing loss and to analyze the interaction between genetics and environmental factors.

Methods: Total of 130 infants were performed detailed audiological evaluation as well as the detection of the popular deafness gene mutations in GJB2 gene, SLC26A4 and mtDNA12SrRNA. Of them, 84 cases were performed the computer tomography or magnetic resonance imaging examinations.
