Can you tell me how can the chromosomal conditions , trisomy x, xyy syndrome and turner syndrome differ?

Can you tell me how can the chromosomal conditions , trisomy x, xyy syndrome and turner syndrome differ?

Good online sites: Xxx and xyy have relatively little impact on those who have them and are usually incidental findings -- this is actually true despite the hoopla over xyy. I have three physician colleagues who have turner's xo and do fine. http://ghr.nlm.nih.gov/ is really good (thanks uncle sam). ...Read more

Trisomy (Definition)

Ordinary chromosomal traits require a pair of chromosomes to determine the traits. Occasionally, as a mistake in cellular division, there is a tripling of one of the chromosomes. When these occur, they usually cause unpleasant, and sometimes deadly conditions in the inheritor of these traits (e.g. Down's). Many we do not know about as they are ...Read more

Is it more lethal to have a trisomy of autosomes or of sex chromosomes?

Are chromosomal abnormalities, such as trisomy, confined to certain parts of the body?

Are chromosomal abnormalities, such as trisomy, confined to certain parts of the body?

Usually: The vast majority of trisomy patients will have the trisomy in every cell of their body. There is a small percentage that will be what is called a mosaic, where the trisomy effects a fraction of the cells. In theory the trisomy starts in one group of cells and continues to all that develop after the change, but another normal line also produces normal tissues. The amount affects the outcome. ...Read more

Testing: You and your husband can undergo genetic testing to see if either of you are a carrier of any genetic mutations that are likely to be passed on during conception. This is a blood test for both of you. In most cases the parents are not carriers and the genetic mutation that occurred during conception was spontaneous and not likely to recur. ...Read more

Can comprehensive chromosome screening (CCS) in IVF screen for (1) partial trisomy, (2) unbalanced translocation, and (3) balanced translocation? Does testing parental karyotyping before CCS help?

Can comprehensive chromosome screening (CCS) in IVF screen for (1) partial  trisomy, (2) unbalanced translocation, and (3) balanced translocation? Does testing parental karyotyping before CCS help?

Test for Aneuploidy: Aneuploidy is the term used to describe any embryo with either too many or too few chromosomes. It is the cause of greater than 60% of miscarriages, as well as the most likely reason that patients do not get pregnant from an IVF cycle. The purpose of CCS is to analyze, select and transfer only embryos that do not have abnormalities in their number of chromosomes. A genetic consult is needed; ...Read more

What is patau syndrome, a trisomy?

Trisomy 13: Patau syndrome is also called trisomy 13. It occurs when a baby has 3 copies of the number 13 chromosome instead of the usual 2 copies. It causes severe physical problems and most babies with trisomy 13 die before birth or within the first year after birth. It usually happens because of an accident which occurs when the egg is fertilized, and occurs more commonly as mothers get older. ...Read more
