| FISH ANALYSES |
CCR FISH analysis with a probe for the steroid sulfatase gene at Xp22.3 showed one of the X chromosomes to be deleted for the steroid sulfatase gene for this X-linked ichthyosis subject. |
| |
| steryl-sulfatase |
According to the submitter, biochemical test results for this subject showed decreased enzyme activity. EC Number: 3.1.6.2 |
