If there is an extra chromosome 18 then the patient has edwards syndrome or trisomy 18. This test can be done after the baby is born or it can be done in utero by amniocentesis (amniotic fluid taken from the uterus is tested). ...Read more

Sporadic event: The preparation of an egg for fertilization includes reducing all the chromosomes (22 regular pairs + a sex chm pair) from pairs to singles. The sperm then brings a single 1-22 regular +a sex chromosome. If the egg has a pair of 18 chms, then when the sperm adds the single 18 there is 3, this creates the chms imbalance in every skin cell of the fetus & results in the defects of edward syndrome. ...Read more
