Structural analysis of mitochondrial rRNA gene variants identified in patients with deafness

Introduction Aminoglycoside antibiotics (AGs) are some of the most commonly prescribed antibacterials, despite their well-known capacity to cause toxic side effects to the kidneys and inner ear (Huth et al., 2011). Although their use in the industrialized world is usually limited to severe infections, they remain very popular in the…
