Juvenile cerebromacular degeneration is also called as Tay-Sachs disease (TSD). TSD is a rare, progressive, neurodegenerative, genetic disorder in which harmful quantities of a fatty substance called ganglioside GM2 accumulate in the nerve cells in the brain (McKusick, 2000; National Institute of Neurological Disorders and Stroke [NINDS], 2000; National Organization for Rare Disorders [NORDJ, 2000).
