Etiology
It is due to seeding from the bloodstream and is most commonly viral in etiology. [ajnr.org]
Of note, there’s some debate about the molecular etiology of nonsyndromic sensorineural hearing loss in subjects with only one detectable GJB2 mutation. A minority of such cases is explained by digenic etiology of GJB2 with GJB3 or GJB6. [bredagenetics.com]
