Data from a mass screening program for identification of persons who are heterozygous for Tay-Sachs disease have been analyzed for the effects of oral contraceptive steroids on the activity in serum of hexosaminidase (hex) and the various hex isozymes. Women using oral contraceptives show a significantly higher total serum hex activity, reflecting mainly an increase in the heat-stable hex isozyme (hex I), and a smaller increase in the heat-labile hex A than do women using no medications. The changes in women using oral contraceptives are qualitatively similar to those observed during pregnancy. The distribution of responses to oral contraceptives is unimodal, and some of the variations may be related to differences in amount of steroid ingested. In addition, underlying genetic variation may contribute to the observed differences in enzyme activities.
