A patient with a known family history of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) due to the MT-
TL1
m.3243A>G mutation presented with mild myalgia and very minor upper limb proximal muscle weakness. Muscle histology revealed low levels of cytochrome oxidase-negative fibres and non-specific
myositis
. Using the last "hot cycle" polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP), the MELAS MT-
TL1
m.3243A>G mutation was only detected in urine, and not in hair, blood or skeletal muscle. This report highlights the need to screen various tissues to achieve an accurate mitochondrial genetic diagnosis and suggests the likelihood of
myositis
arising secondary to the MELAS MT-
TL1
m.3243A>G mutation.
