Dosage of the Sts gene in the mouse.

摘要

In this study we compared steroid sulfatase levels in XO, XX, and XY mice and carried out a clonal analysis in fibroblast cell cultures from mice heterozygous for the steroid sulfatase deficiency gene and heterozygous at the X-linked electrophoretic phosphoglycerate kinase locus. The combined results indicate that the murine steroid sulfatase locus is not dosage compensated and is not subject to X-inactivation. With respect to X-inactivation, it behaves in a somewhat different way from the closely linked sex-reversed gene and the human steroid sulfatase locus.
