| 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; <5% activity. |

| Cytogenetics |
Chromosome X: DELETION Aneuploid Segment (-)Xp22>Xp22 |
| Remarks |
Sardinian; G6PD deficient, Xg(a) positive; < 5% of normal fibroblast steroid sulfatase activity; normal arylsulfatase A and B activity; DNA does not hybridize STS-3 cDNA gene probe |
