GJB2 and sensorineural hearing loss disorder: As a result, our patients were selected based on the presence of congenital SNHL compatible with autosomal recessive inheritance, absence of two hearing loss-associated GJB2 mutations, and the presence of only one known mutation in SLC26A4. In these individuals, we performed MLPA of SLC26A4 and in a subset we also sequenced the coding regions and splice sites of FOXI1 and KCNJ10 to evaluate alternative etiologies.
