Summary Neuronal ceroid lipofuscinoses are the most common neurodegenerative childhood onset disorders characterized by autosomal recessive inheritance epileptic seizures progressive psychomotor deterioration visual failure and premature death At least seven subtypes of childhood onset neuronal ceroid lipofuscinoses have been identified of which the late infantile onset forms are genetically the most heterogeneous We present a five year old girl with late infantile neuronal ceroid lipofuscinosis who presented with progressive psychomotor retardation ataxia and epilepsia Palmitoyl protein thioesterase activity was very low and a homozygous mutation was identified in CLN2 gene Turk Arch Ped 2010; 45: 155 7 Key words: CLN2 gene electron microscopy neuronal ceroid lipofuscinosis
