GJB2 and hearing loss disorder: The deletion-proximal connexins (GJA3, GJB2, and GJB6) were initially considered genes of interest, as they have been reported as part of 13q12.11 microdeletions in the literature described above and linked to both hearing loss and cataract formation [32]; however, in our RNAseq data, only GJB6 exhibited any significant expression differences in the affected corneal epithelium, and this effect was quite modest.
