X-linked icthyosis. A sulphatase deficiency

G Koppe, A Marinković-Ilsen, Y Rijken

    Archives of Disease in Childhood
    |October 1, 1978
    PubMed
    Summary

    Low estrogen levels during pregnancy may be linked to X-linked ichthyosis. This genetic skin condition in infants was associated with a deficiency in arylsulphatase C enzyme activity in both placentas and affected children.

    Area of Science:

    • Biochemistry
    • Genetics
    • Dermatology

    Background:

    • Ichthyosis vulgaris is a genetic skin disorder.
    • X-linked ichthyosis is a specific inherited form.
    • Previous research has not identified specific biochemical markers for this condition.

    Purpose of the Study:

    • To investigate potential biochemical factors in X-linked ichthyosis.
    • To examine enzyme activity in patients with ichthyosis and their mothers during pregnancy.

    Main Methods:

    • Assessed urinary estrogen levels in pregnant women.
    • Performed histochemical analysis of placental and skin tissue for arylsulphatase C activity.
    • Compared enzyme activity in affected individuals with healthy controls.

    Main Results:

    • Three infants born to mothers with low estrogen excretion developed X-linked ichthyosis.
    • Placental and skin tissues from affected children showed a deficiency in arylsulphatase C activity.
    • Nine adult patients with X-linked ichthyosis also exhibited deficient arylsulphatase C activity.

    Conclusions:

    • A deficiency in arylsulphatase C enzyme activity is implicated in the causation of X-linked ichthyosis.
    • This enzyme deficiency may be detectable during pregnancy.
    • Further research is warranted to explore therapeutic interventions targeting sulfatase deficiency.
