Question

Can you tell if a newborn has Down’s syndrome?

Answer 1

Developmental and intellectual impairments are caused by a hereditary chromosome abnormality. Down's syndrome is a genetic disease produced by an increasing number of chromosomes than normal as a result of improper cell division. Down's syndrome is characterized by a distinctive facial appearance, intellectual impairment, and developmental delays.

Complete answer:
Yes, based on the physical features of the newborn one can predict whether the neonate is suffering from Down’s syndrome. However, the final confirmation is done after various diagnostic tests.
The following features may be seen in newborns with Down Syndrome:
1. Head and ears are small.
2. A slender neck
3. Face that has been flattened
4. Hands and feet are small.
5. Eyes that are slanted upward
6. Brush fields are present.
7. With small hands and short fingers,
8. Between the first and second toes, there is a deep groove.

Additional information:
Some diagnostic tests confirm Down’s syndrome even before the child is born.
Diagnostic tests are generally used to confirm a Down syndrome diagnosis following a positive screening test. The following are examples of diagnostic tests: CVS (chorionic villus sampling) analyses placental tissue. Amniocentesis is a procedure that analyses the amniotic fluid (the fluid from the sac surrounding the baby).

Note:
A genetic condition is an illness caused in part or entirely by a deviation from the usual DNA sequence. A single gene mutation (monogenic disorder), several gene mutations (multifactorial inheritance disorder), a combination of gene mutations and environmental factors, or chromosomal damage (variations in the number or shape of complete chromosomes, the gene-carrying structures) can all cause genetic illnesses.
