Counseling needs and attitudes toward prenatal diagnosis and abortion in fragile-X families

The genetic counseling need of 32 women of normal intelligence at-risk for having children with the fragile-X syndrome (FXS) were determined by a questionnaire study which included assessment of their attitudes toward prenatal diagnosis and the option of pregnancy termination. Eighteen (56%) of the women had one or more children with the FXS and 14 (44%) had no affected children. Twenty-six (81%) of the subjects stated that they would choose to have prenatal diagnosis and 9 (28%) indicated they would terminate an affected pregnancy. There was no significant difference between women who had affected children and those who did not have affected children, nor between Catholics and non-Catholics regarding acceptance of prenatal diagnosis. Catholic women were less likely to consider pregnancy termination than non-Catholics, but the majority of subjects (56%) were unsure what they would do if a fetus they were carrying was found to be affected. Issues the subjects considered most important for discussion with a genetic counselor included: 1) availability of treatment, 2) risk for having an affected grand child, 3) expectations for future functioning of affected children, and 4) availability of prenatal diagnosis.
