WebMELAS is a mitochondrial-related disease typically present in children or young adults. Several mutations in mtDNA have been associated with MELAS. As mentioned earlier, muscle biopsies from MELAS patients can show COX-positive ragged red/blue fibers. WebGenetic Testing. Genetic testing should be completed looking for the most common MELAS-associated mutations. Initial screening should investigate for the m.3243A>G mutation, as this is present in 80–90% of cases with MELAS [19,21–23]. As such, targeted mutation analysis of MT-TL1 is usually the first step in diagnosis.
