Sakpichaisakul K Mail, Taeranawich P , Nitiapinyasakul A , Sirisopikun T

Sandhoff disease is a GM2 gangliosidosis that is rare in Thailand. The authors report a Thai family with two
children known to have infantile form of Sandhoff disease. The index case exhibited mitral valve prolapse with mitral
regurgitation as an early sign, which is a rare presentation in Sandhoff disease. Thereafter, the patient had developmental
regression, startle reaction, and cherry red spots. The diagnosis was confirmed by biochemical analysis.
