Eggs splice, or the two fraternal twins suffer from vanishing twin syndrome and the twin literally absorbs the other twin, what does this mean?
Conjoined placenta: Unfortunately, the placenta often becomes shared between the twins and the one with the better access to the cotyledons of the placenta thrives and the other twin does not. An alternate scenario is when the two fraternal fetal twins are joined together but one does not develop as well as the other prior to placental development in the first trimester. ...Read more
What mutations cause fetal alcohol syndrome facial features in a baby or child, whose mother was a non-drinker?
First of all...: ...Alcoholics frequently deny that they drink; so if there are features suggesting fas, you have to be sure the mother really is a non-drinker. That said, cornelia de lange syndrome, velocardiofacial syndrome (vcfs), & dubowitz syndrome - & probably others - share features with fas, though they are rarer. A precise diagnosis requires a thorough exam and lab testing by an expert in this field. ...Read moreSee 1 more doctor answer

Demise of one fetus: Vanishing twin syndrome is the demise of one twin sometime during the pregnancy. One study suggested it occurred about 20-30% of twin pregnancies. Most commonly it occurs early in the pregnancy and generally the remaining fetus has a good outcome. Its' occurrence later in pregnancy can be associated with adverse maternal and fetal outcomes. ...Read moreSee 1 more doctor answer
I know gestational diabetes can cause hypoglycemia&seizures in baby shortly after birth; is it possible for gest. Diabetes to cause in utero seizures?
Vanishing twin syndrome (lost at 5+ weeks), what is the likelihood of the remaining twin having something wrong with it?
Increased risk LBW: Compared to singletons, the surviving twin of VTS is at slightly greater risk of premature delivery, low birth weight and, for twin loss after 8 weeks gestation there is an increased risk for cerebral palsy. Loss of a twin at five weeks greatly reduces the risk for the surviving twin to have any adverse consequences. ...Read moreSee 1 more doctor answer
Depends on cause: Babies don't need kidneys much during pregnancy because the placenta does that job.They do make pee that ends up as amniotic fluid. The right amount of fluid creates extra volume in the womb that pushes back against the muscular womb & allows the lungs to develop.(important) Things that stop or limit fluid formation includes absent kidneys or blockage in the outflow. Such defects can be a problem ...Read moreSee 1 more doctor answer
Why rhd incompatibility of the mother and fetus doesn't affect the present fetus but subsequent pregnancies?
See below: The incompatibility occurs when the mother is exposed to the blood of the new baby. This usually occurs at delivery. The mother then makes antibodies to that "foreign substance" and this can adversely affect the next pregnancy as the mother's immune system will see it as a "foreign" body and want to get rid of it. This problem is usually treatable with an injection at the birth of the first child. ...Read more
Is a small gestational sac in relation to the fetus a sign of a chromosomal abnormality. Fetus 9w sac 7w. Doctor and research have me very worried.
Hard to answer...: At such an early stage, imaging and interpretation is hard. There are associations between size and abnormalities. But it is impossible to look at a minimally smaller size and conclude anything, especially chromosomal disorders. It is best not to worry, but follow this serially and monitor progress. Your OB is the best judge of this and should advice you of intervention if at all needed. ...Read moreSee 1 more doctor answer
I have a fraternal twin brother with microdeletion 22q11.2 (velocardiofacial syndrome). What are the chances my children will have the same disorder?
Minimal: These odd micro-deletion syndromes are thought to arise as new defects which could be dominantly passed. Unless you carry it, you won't pass it to your kids and they would have the same risk as the general population to acquire it (new). You might benefit from discussing any and all genetic risk issues from both sides of the family with a geneticist. ...Read more
