The polymorphisms of the MBL2 and MIF genes associated with Pediatric Cochlear Implant Patients.

Mannose-binding lectin and macrophage migration inhibitory factor gene polymorphisms are associated with several acute/chronic autoimmune or inflammatory diseases. The aim of this study was to investigate if there was any association between mannose-binding lectin 2 (MBL2) and macrophage migration inhibitory factor (MIF) gene polymorphisms and profound congenital sensorineural hearing loss in children who underwent cochlear implantation.,A total of 62 patients with congenital hearing loss and 80 age- and sex-matched healthy controls were evaluated for codon 54 A/B polymorphisms in MBL2 and the-173 G/C polymorphism in MIF by using the polymerase chain reaction and restriction fragment length polymorphism method.,The frequency of the BB genotype of MBL2 and MIF -173 GC genotype were statistically significantly higher in the patient group than in the controls (p=0.0127, p=0.0408, respectively).,In this study, we found that a subject who is homozygous for the variant allele B of codon 54 of the MBL2and heterozygous for variant allele C of -173 MIF has a risk factor for sensorineural hearing loss.
