Brief Summary

To test the hypothesis that in patients with a clinical diagnosis of familial hypercholesterolemia (FH), genetic testing and identification of a causative mutation might enhance the success of family-based cascade screening.

Conditions

Hypercholesterolemia, Familial

Keywords

Familial Hypercholesterolemia; Genetics; Cascade screening

Outcome Measures

Primary Outcomes (1)

• Number of probands with relatives enrolled

  The primary outcome of this study was the number of probands with family members enrolled in the study within 52 weeks of results being returned to probands. Investigators compared the proportion of probands with a relative enrolled in the genetic testing group with the proportion of probands with a relative enrolled in the usual care group (lipid testing only). Relative enrolment was defined as the return of a test kit within the study time frame.

  52 weeks after genetic/lipid testing results are returned to probands

Secondary Outcomes (2)

• The number of relatives enrolled in the study 52 weeks after results were returned to probands

  52 weeks after results are returned to probands

• The number of family members diagnosed with FH 52 weeks after results were returned to probands

  52 weeks after results are returned to probands

Other Outcomes (1)

• Proband perceptions about their high cholesterol including its etiology, management and heritability at 20 weeks after enrollment compared to baseline

  20 weeks after enrollment
