EMILIN2 and hearing loss disorder: Therefore, we expect that the Ahl gene, associated with age related hearing loss, has no effect on BM structure during development, while it could be involved in the alterations in BM structure observed at 6 months old mice54,55 However, since both Emilin − 2−/− and Emilin − 2+/+ animals were on the same genetic background, we feel confident that any structural differences we report are due to alterations in emilin2 protein.
