Question
Answer: Hi dear, It is nothing but down syndrome.Down syndrome is a genetic disorder,where there is a problem in third copy of chromosome 21.this happens when the chromosome 21 in egg or sperm fail to separate during conception.the child with down syndrome would have slow growth mental and physical,and also have typical facial features.so the NT scan at 11-13 weeks can detect if the baby has high risk of down syndrome by measuring the thickness of nuchal fluid at the back of its neck.as the thickness increases,the risk also increases.unfortunately there is no cure to this,it's just that parents get to know about it at the early stage.further screening is required if there is a risk of down syndrome is observed in NT scan.

Question: Trisomy-21 its positive in my blood test...is there any way to cure it
Answer: Dear your doctor will be suggesting you further test like Diagnostic tests such as chorionic villus sampling (CVS) and amniocentesis which  can tell you with for certain whether your child has a chromosomal abnormality. There is no cure for Down syndrome. Doctors are not certain how to prevent the chromosomal error that causes Down syndrome. To date, there is no reason to believe that a parent could have done anything to cause or prevent the birth of a baby with Down syndrome. Hope i helped.
