[Phenotype and genotype analysis of recessive hereditary moderate sensorineural hearing loss caused by new mutations in OTOGL gene].

Pathogenic variants in OTOGL gene is an important genetic factor leading to moderate sensorineural hearing loss. The newly discovered variant sites c.2826C>G, c.4455G>A and c.875C>G enrich the variant spectrum of OTOGL gene. The results of the current study provide a basis for genetic counseling of the related families and a new target for the treatment of hereditary hearing loss in the future.
