In the calculation of patient-specific risk for trisomy 21 the maternal age-related a-priori risk is multiplied by the likelihood ratios for the fetal NT and maternal serum biochemical markers. Consequently for the same measurements of NT free β-hCG and PAPP-A the final risk will vary with maternal age and for the same risk cut-off both the detection and false-positive rates increase with. Children with trisomy 21 have a 10- to 50-fold increased risk for leukemias compared with unaffected children 5 and the risk of acute myeloid leukemia AML is especially high compared with their peers.

Fifteen to thirty percent of women with trisomy 21 are fertile and they have about a 50 risk of having a child with Down syndrome. There is no evidence of a man with Down syndrome fathering a child. While the incidence of births of children with Down syndrome increases with maternal age more children are born to women under the age of 35 due to higher fertility rates.

TRISOMY 21 CHROMOSOMAL DEFECTS MATERNAL AGE RISK COUNSELLING NUCHAL TRANSLUCENCY ABSTRACT Objective To provide estimates of maternal age- and gestational age-related risks for trisomy 21. Methods The prevalence of trisomy 21 was examined in 57 614 women who had fetal karyotyping at 916 weeks. The estimated trisomy-21 risk from maternal age and fetal nuchal-translucency thickness was 1 in 300 or higher in 7907 83 of 95 476 normal pregnancies 268 822 of 326 with trisomy 21 and 253 779 of 325 with other chromosomal defects.

The 5 of the study population with the highest estimated risk included 77 of trisomy-21 cases. Trisomy 21 have a adjusted risk of 1663. Our objective was to examine the performance of first-trimester screening for trisomies 21 18 and 13 by maternal age fetal nuchal translucency NT thickness fetal heart rate FHR and maternal serum-free beta-hCG and pregnancy-associated plasma protein-A PAPP-A.

At 20 a woman would have a risk of 1 in 1500 having a child with Downs syndrome. At 30 the risk is 1 in 1000. This risk would increase from 1 in 100 to 40 years and 1 in 28 to 50 years.
