Tay-Sachs Disease: A Rare Storage Disorder in Children

Tay-Sachs disease is an autosomal recessive lysosomal storage disorder cause by deficiency of enzyme Beta Hexosaminidase A and leading to accumulation of GM2 gangliosides mainly in CNS, results in progressive loss of neurological functions. We report a case of 14 month old male child presented to us with neuro-developmental regression, convulsions and bilateral cherry red spot on funduscopy. The diagnosis of Tay-Sachs disease was made by marked decrease level of enzyme Hexosaminidase A. Key words: Lysosomal storage disorder, GM2 gangliosides, neuro- regression, cherry red spot, Enzyme replacement therapy.
