| beta-N-acetylhexosaminidase (hexosaminidase B) |
According to the submitter, biochemical test results for this subject showed decreased enzyme activity. EC Number: 3.2.1.52 |
| |
| Remarks |
Deficient hexosaminidase A and B; < 1% of normal fibroblast pre B-chain mRNA; 0.3% of normal fibroblast Hex A activity; Hex B gene shows a partial gene deletion localized to the 5' end |
