Is there a cure?
No, not yet.
- One in every 691 babies in the U.S. is born with Down syndrome, making it the most common chromosomal condition.
- The likelihood of giving birth to a child with Down syndrome increases with maternal age, however, 80% of babies with Down syndrome are born to women under 35 years of age because this age group gives birth most frequently.
Take out the extra chromosome in trisomy 21 so instead of 47 chromosomes the baby will have 46 before he/she is born.
