The genetic developmental defect is spelled "Down Syndrome" or sometimes "Down's Syndrome."
it leads to death
Down's Syndrome is the unfortunate effect of an error that takes place during cell division at fertilisation. The error leads the child to have an extra 21st chromosone which causes cognitive and physical impairments.

no it's not a birth defect...it's a disease caught way before birth..Down syndrome is when a person has 1 more chromosome than normal people.
Down syndrome is caused by an additional chromosome while PKU is due to a mutation or defect in a gene.
No, down syndrome is caused by a genetic defect where there is an extra chromosome in most,if not all, of the cells of a body. it is not caused by a drug.
Down's Syndrome is an example of a birth defect characterized by an abnormality of the chromosome structure.
no because since they both have down syndrome, they will have 100 percent that they will have a down syndrome baby
Ventricular septal defect affects the ventricles common in babies with down syndrome while atrial septal defect is affecting the atrium.
Nothing really leads to Down Syndrome, it is just an extra chromosome in the 21st pair. (otherwise known as Trisomy 21)
it leads to death
