Sandhoff Disease, also known as hexosaminidases a and b deficiency, is related to gangliosidoses and gm2-gangliosidosis, ab variant. An important gene associated with Sandhoff Disease is HEXB (Hexosaminidase Subunit Beta), and among its related pathways/superpathways are Metabolism and Diseases of glycosylation. The drugs Miglustat and Glycoside Hydrolase Inhibitors have been mentioned in the context of this disorder. Affiliated tissues include spinal cord and eye, and related phenotypes are reduced beta-hexosaminidase activity and macrocephaly
