In addition, the symptomatic progression of hearing loss and vertigo in MD were correlated with increased levels of lymphocytes in systemic autoimmune diseases (R2 = 0.52, p = 0.01 for hearing loss with CD19 cells and R2 = 0.12, p = 0.05 for hearing loss CD8 cells) [22]. The gene discussed is CD8A; the disease is Menkes disease.
