Background: GM2 gangliosidosis variant 0 (human Sandhoff disease) is a lysosomal storage disorder caused by deficiencies of acid ?-hexosaminidase (Hex) A and Hex B because of an abnormality of the ?-subunit, a common component in these enzyme molecules, which is coded by the HEXB gene. Objective: To
GM2 gangliosidoses are inherited disorders of GM2 ganglioside metabolism. Its inheritance is autosomal recessive. There are three major, biochemically dis- tinct types: B, O, and AB. Among the B and O types, infantile, juvenile, and adult forms can be distin- guished; the AB variant is known only as an infantile form.
the degradation of gangliosides (10, 12). This paper presents evidence that a component of an activating factor necessary for the degradation of ganglioside GM2 and glycolipid GA2 cata- lyzed by hexosaminidase A is defective in variant AB of in- fantile GM2 gangliosidosis.

Abstract. Clinical phenotypes of GM2-gangliosidosis are complex. In the past 5 years it has become possible to dissect out the phenotypic complexity on the basis of abnormalities on the DNA level. Available data on the 18 disease-causing mutations so far identified in the P-hexosaminidase ?-gene allow an oversimplified

GM2-gangliosidosis, AB variant is a rare inherited disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord. Signs and symptoms of the AB variant become apparent in infancy. Infants with this disorder typically appear normal until the age of 3 to 6 months, when their development slows and
A deficiency of any one of these proteins leads to storage of the ganglioside, primarily in the lysosomes of neuronal cells, and one of the three forms of GM2-gangliosidosis, Tay–Sachs disease, Sandhoff disease or the AB-variant form.
