Down syndrome is caused by the presence of an extra chromosome 21, resulting in three copies (trisomy 21) rather than the typical two copies. Individuals with Down syndrome may have some distinctive physical features like a flattened face, slanted eyes, and small hands and feet. The condition does not require medical treatment as it is not a disease, but some associated health issues may need to be monitored. Down syndrome can be detected during pregnancy through advanced ultrasound examination or by analyzing the mother's blood sample. It is not an infectious condition and risk increases with the age of the mother.

DOWN
BY: IRATI AND LEYRE

2. CAUSE
• THE HUMAN BODY IS FORMED BY CELLS THT CONTAIN A
CENTRAL PART CALLED NUCLEUS. THE NUCLEUS OF CELLS
CONTAIN 23 PAIRS OF CROMOSOMES. SOMETIMES THERE IS
ONE MORE CROMOSOMS IN THE PAIR 21, SO THERE ARE
THREE, WHICH PRODUCES DOWN SYNDROME.

4. TREATMENT
• Down syndrome is not a disease and therefore
does not require medical treatment. The health of
children with trisomy 21 need not differ from that of
any other child. Many children are perfectly
Healthy, that is, they do not present any disease.

7. HOW DO YOU KNOW THE BABY HAS
DOWN SYNDROME?
• YOU CAN SEE ECOGRAPHY YOU COULD SEE SOME SIGNS :
EG, THEY DON´T HAVE NASAL BONE.
• WE CAN SEARCH BABY CELLS IN THE MOTHERS BLOOD AND
SEE THE CROMOSOMS .

8. CHROMOSOMES
Chromosomes are rod / string structures found in
the nucleus of the cell. Chromosomes contain
genes made up of DNA.Thus, our hereditary
information is located on the chromosomes.
Normal human cells (embryos, fetuses, children or
adults) contain 46 chromosomes or 23 pairs of
chromosomes.hreceived 23 cromosoms from each
parent through their germ cells (sperm or oocytes).

9. ( EXTRA INFORMATION )
