Quizplus · Accepted Answer

Trisomy-21 or Down syndrome is caused by a chromosomal abnormality where there is an extra copy of chromosome 21. Genome editing, such as with TALEN or CRISPR, cannot simply remove an entire chromosome, and there are currently no known ways to correct this type of chromosomal abnormality. However, gene therapy may provide some possibilities for treating symptoms of Down syndrome.
