[/INST] Down syndrome is a genetic condition in which a person has 47 chromosomes instead of the usual 46. A woman's risk of having a child with Down syndrome increases as she gets older. The risk is significantly higher among women age 35 and older.Couples who already have a baby with Down syndrome have an increased risk of having another baby with the condition.IVF don`t increase risk of DS.Disclaimer </s>
