The present invention relates to marker POLD1 for diagnosis of sensorineural hearing loss and the use thereof and, more particularly, to a kit and a composition for diagnosing a sensorineural hearing loss disease, comprising a polynucleotide including a consecutive nucleotide sequence selected from the nucleotide sequence of an exon region of a POLD1 gene, or a complementary polynucleotide thereto, which is used to detect a mutation of the POLD1 gene, and a method for detecting a mutation of genomic DNA to provide information on diagnosis. A kit or composition according to an embodiment can be used to analyze a mutation of the POLD1 gene at high sensitivity and accuracy, and sensorineural hearing loss can be effectively diagnosed on the basis of the analysis result.
