The lysosomal enzyme, beta-hexosaminidase, exists as two major isoforms; HexA and HexB. HexA is an alpha beta-subunit heterodimer and HexB a beta-subunit homodimer. Both isoforms can remove nonreducing beta-N-acetyl-D-glucosamine residues, whereas HexA hydrolyzes charged substrates as G(M2) gangliosides as well. beta-Hexosaminidase is present in both human and rabbit tear fluid and is secreted ...
Karyotypical alteration of chromosome 5 and in particular band 5q13 is a frequent finding in hairy cell leukemia (HCL). We have previously identified a number of candidate genes localized in close proximity to a constitutional inv(5)(p13.1q13.3) breakpoint in one HCL patient. These included beta-hexosaminodase HEXB, frequently mutated in the lysosomal storage disorder Sandhoff disease. We now r...
Molecular pathology of Sandhoff disease with p.Arg505Gln in HEXB: application of simulation analysis
Sandhoff disease is a neurodegenerative disease caused due to deficiency of hexosaminidase (HEX) A and B. A 1-year-old male child presented with regression of milestones, exaggerated startle response, decreased vision, and seizures from 6 months of age. The child had coarse facies without hepatosplenomegaly. Serum levels of β hexosaminidase total (A + B) were low. Genetic testing for Sandhoff d...
