Just wanted post some additional info. The latest stats say that Down syndrome actually occurs in 1 out of 733 live births (see http://www.ndss.org). The ACOG (The American College of Obstetricians and Gynecologists) now recommends that ALL pregnant women be screened for Down syndrome before their 20th week of pregnancy, not just women over 35. Between 90%-98% of parents choose to abort when given a Down syndrome diagnosis. New findings are also showing that increased age of the father may also be a risk factor. While maternal age is a risk factor, the majority of children with Down syndrome are born to women UNDER 35. The only test that can confirm Down syndrome is an amnio. Some studies say that for every child diagnosed with Down syndrome through amnio, 3 typically developing fetuses die from miscarriage as a result of amnio. Due to early intervention, medical advances, and awareness life expectancy for people with Down syndrome has increased from 25 in 1983 to 56 in 2008. The oldest man living with Down syndrome just passed away in march at the age of 68.

"Down syndrome occurs in one out of every 733 live births, and more than 350,000 people in the U.S. have this genetic condition. One of the most frequently occurring chromosomal abnormalities, Down syndrome affects people of all ages, races and economic levels. Today, individuals with Down syndrome are active participants in the educational, vocational, social and recreational aspects of our communities. In fact, there are more opportunities than ever before for individuals with Down syndrome to develop their abilities, discover their talents and realize their dreams. For example, more teens and adults with Down syndrome each year are graduating from high school, going to college, finding employment and living independently." taken from http://www.ndss.org
