Edwards Syndrome - Epidemiology

Epidemiology

Edwards syndrome occurs in approximately 1 in 6,000 live births, but more conceptions are affected by the syndrome because the majority of those diagnosed with the condition prenatally will not survive the prenatal period. Although women in their 20s and early 30s may conceive babies with Edwards syndrome, the risk of conceiving a child with Edwards syndrome increases with a woman's age. The average maternal age for conceiving a child with this disorder is 32½.
