Sandhoff Disease Market to Reach USD 1.2 Billion by 2034

Sandhoff disease is a rare, inherited lysosomal storage disorder caused by mutations in the HEXB gene, leading to a deficiency in the beta-hexosaminidase A and B enzymes. This deficiency results in the accumulation of GM2 gangliosides within nerve cells, causing progressive neurodegeneration. Sandhoff disease presents in various forms-infantile, juvenile, and adult-onset-with the infantile type being the most severe and often fatal by early childhood.
