Comment on list classification: In Frejo et al 2017 (PMID:29326686) an immune genotype array with 420 bilateral MD patients (NOT familial) identified an association with bilateral MD at 6p21.33 (leading signal rs4947296). In vitro studies suggest that the carriers of the risk genotype may develop an NF-κB-mediated inflammatory response in MD. Cabrera et al 2014 (PMID:25397881) found by genotyping array two potential regulatory variants in the NFKB1 gene (rs3774937 and rs4648011) were associated with a faster hearing loss progression in patients with unilateral sensorineural hearing loss in MD patients (716 patients).

Green List (high evidence)

This gene is not associated with familial MD, but it is related with inflammation in the carriers of rs4749296.
We conducted a case-control study in two phases using an immune genotyping array in a total of 420 patients with bilateral MD and 1,630 controls. We have identified the first locus, at 6p21.33, suggesting an association with bilateral MD [meta-analysis leading signal rs4947296, OR = 2.089 (1.661-2.627); p = 1.39 × 10-09]. Gene expression profiles of homozygous genotype-selected peripheral blood mononuclear cells (PBMCs) demonstrated that this region is a trans-expression quantitative trait locus (eQTL) in PBMCs. Signaling analysis predicted several tumor necrosis factor-related pathways, the TWEAK/Fn14 pathway being the top candidate (p = 2.42 × 10-11). This pathway is involved in the modulation of inflammation in several human AD, including multiple sclerosis, systemic lupus erythematosus, or rheumatoid arthritis. In vitro studies with genotype-selected lymphoblastoid cells from patients with MD suggest that this trans-eQTL may regulate cellular proliferation in lymphoid cells through the TWEAK/Fn14 pathway by increasing the translation of NF-κB. Taken together; these findings suggest that the carriers of the risk genotype may develop an NF-κB-mediated inflammatory response in MD.
