This is an enzyme called ganglioside, that is a fatty substance. Another reason why tay sachs could appear is a change in chromosomes. This is chromosome number 15. The gene is the HEXA gene, or hexosaminidase A. This is a recessive disorder that you can only inherit if both parents have tay sachs. Some symptoms to know if you have this disease is weakened muscles, startling of loud noises, seizures, hearing loss, blindness, and paralysis.
