Chromosome that causes more Down syndrome is the chromosome number 21: Hence the term “trisomy 21″. The fact that the cause of Down syndrome is a genetic, hereditary not to say: Down syndrome is an inherited disorder in only 2% of cases.
The result of ‘chromosome of Down syndrome leads to a variable degree of delay in mental development, physical and motor of the child. The presence of Down syndrome is diagnosed in infants with a ‘chromosomal analysis done on a blood sample, and through a number of features encountered by the pediatrician, whose sight is the almond-shaped eyes in children with Down syndrome .
The odds of having a child with Down syndrome increases with ‘rising’ s maternal age.
DOWN SYNDROME AND PREGNANCY: prenatal testing

Findings prenatal (during pregnancy and before the birth of the child) are executable without the need for hospitalization, and are of two types: diagnostic and statistical purposes.

STATISTICAL TEST IN PREGNANCY: do not provide diagnosis, but indicate the change in the risk of having a Down child than the average over all ‘age of the mother.
- Nuchal translucency, ultra screen and tri test shall be conducted between the 11th and 16th week of gestational age. All tests are based on an ‘ultrasound and are associated with maternal blood sample. Tests are not invasive and no risk of miscarriage. If the test result indicates a higher than average risk can be investigated (parental discretion) with diagnostic tests.

DIAGNOSTIC TESTS IN PREGNANCY: provide the report as fetal chromosome map. Among the diagnostic tests include:
- Amniocentesis: you run around the 16th to 18th week of gestation. The gynecologist inserts a needle under ultrasound guidance in ‘uterus through the’ belly and removes a small amount of amniotic fluid surrounding the fetus. The risk of an induced abortion is less than ‘1%.
- CVS: runs between the 12th and 13th week of pregnancy. The gynecologist inserts a needle into the ‘uterus and removes some fragments of chorionic tissue (the future placenta). The risk of abortion is’ s 1.5% approximately.
