Approximately one in every 700 babies in the United States is born with Down syndrome, according to the National Down Syndrome Society, citing date from the Centers for Disease Control and Prevention.
About 6,000 babies with Down syndrome are born in the United States each year, making the syndrome the most common chromosomal condition.
People with Down syndrome have an extra, critical portion of chromosome 21 percent in all or some of their cells.
Despite decades of research, the cause of the extra full or partial chromosome is still unknown. However, maternal age has been identified as the only factor linked to an increased chance of having a baby with Down syndrome.
There remains no definitive research that links Down syndrome to environmental factors or the parents' activities before or during pregnancy.
