Hearing impairment in MELAS: new prospective in clinical use of microRNA, a systematic review
Abstract Aim To evaluate the feasibility of microRNAs (miR) in clinical use to fill in the gap of current methodology commonly used to test hearing impairment in MELAS patients. Material and method A literature review was performed using the following keywords, i.e., MELAS, Hearing Loss, Hearing Imp...
