The main components of NARP syndrome are: Neuropathy peripheral neuropathy which mostly affects sensory nerves Ataxia Retinitis pigmentosa Other features include seizures, hearing loss and cardiac conduction defects. It occurs due to a mutation in the MT-ATP6 gene, which results in altered structure or function of mitochondrial ATP synthase leading to decreased ATP production. As it involves a mutation of mitochondrial DNA, it is inherited from mother to child maternal inheritance. Other maternally inherited mitochondrial DNA disorders include: Leigh syndrome, Lebers hereditary optic neuropathy Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes MELAS Ref :Harrisons Principles of Internal Medicine 21st ed .
