SLC26A4 and hearing loss disorder: In our previous analysis of SLC26A4 in patients with hearing loss from the Tyva and Altai Republics (Southern Siberia, Russia), we identified a distinctive spectrum of SLC26A4 variants including well-established pathogenic variants (c.919-2A>G, c.2168A>G) confirmed by functional studies, as well as other known SLC26A4 variants [39].
