Answer

The gene for FH is on chromosome 19; therefore, the inheritance pattern is the same for males and females.

In heterozygous FH, the consequences of severe hypercholesterolemia manifest earlier in men than in women because of the sex protection that benefits women until the postmenopausal years. Although a woman with no other major risk factors for CAD may not develop symptomatic CAD during her lifetime, men are rarely so fortunate.

Homozygous girls and boys have the same risk for a very early cardiovascular event.
