One in every 691 babies in the U.S. is born with Down syndrome, making it the most common chromosomal condition. There are more than 400,000 people living with Down syndrome in the U.S. In 1983, the average life expectancy of a person with Down syndrome was a mere 25-years-old. Today, it's 60.
Down syndrome is a genetic condition that happens when a child is born with an extra chromosome. The extra chromosome affects the way the child's brain and body develop, leading to developmental delays, intellectual disability, and an increased risk for certain medical issues.
Most individuals with Down syndrome have mild (IQ: 50–69) or moderate (IQ: 35–50) intellectual disability with some cases having severe (IQ: 20–35) difficulties. Those with mosaic Down syndrome typically have IQ scores 10–30 points higher than that.
It is a common birth defect, the most frequent and recognizable form of intellectual disabilities (ID), appearing in about one out of every 700 newborns. The average intelligence quotient (IQ) of children with DS is around 50, ranging between 30 and 70.
