A boy was born at term to healthy nonconsangineous parents after an uneventful pregnancy. The neonatal period was uneventful. At 12 months of age his developmental milestones delayed and muscle hypotonia appeared. At 16 months, he developed neurodevelopmental regression, generalized symmetrical hypotonia and absent deep tendon reflexes. His weight, height and head circumference were below the third percentile.

Lab investigations revealed elevated blood lactate at rest. Motor nerve conduction velocity test (MNCV) of the peroneal and median nerve was slowed.

An MR examination of the brain on a 1.5 T magnet was performed [Figure - 1],[Figure - 2],[Figure - 3],[Figure - 4]. What is the diagnosis?.
