Large offspring is a phenonenom which is found mainly in cloned lambs and calves which are the result of embryo manipulation (IVF) (NT). The phenomenon creates oversized offspring due to insulin like growth factor 2 receptor (IGF2R) making protein which blocks the normal growth of cells. When the receptor is deactivated the embryos grow too large. Other symptoms can include enlarged hearts, immature lungs and damaged kidneys. It has not been seen in humans due to IGF2R unable to be deactivated. Large offspring is thought to be a result of the environment the embryos are grown in in both the lab and the donor mother.
No, CFC syndrome is caused by a sporadic mutation.
As the disease is genetic, DS women have nearly a 50% chance of passing on DS to their offspring if the father does not have DS.
An individual with Klinefelter syndrome is male. They are born with at least one extra X chromosome (XXY), which can affect their physical and cognitive development.
Not usually. Only In certain circumstances, can a mutation be passed on to offspring; such as Downs-syndrome.
No, because people with Down syndrome can't have children.
No.
A non-repeat mother without fragile X syndrome cannot pass the condition to her male offspring. Fragile X syndrome is caused by mutations in the FMR1 gene, specifically the expansion of CGG repeats, which typically occurs in carriers with a certain number of repeats. Since the mother does not have the syndrome or carry the premutation, her male offspring would not inherit the genetic mutation associated with fragile X syndrome.
Down's Syndrome is caused mainly by a mutation in the gene. It is a genetic disorder, which means it was passed on from parents to offspring.
No. Parents of Down Syndrome typically are normal genetically and there is no test for parents to determine the possibility of a Down Syndrome offspring. There are no known external factors that are known to contribute to Down Syndrome. It is possible to test for Down Syndrome in the fetus.
Marfan syndrome is an autosomal dominant disorder. An affected person has a 50% chance of passing it on to each offspring, regardless of gender.
Nondisjunction is the failure of chromosome pairs to separate properly during cell division, leading to gametes with an abnormal number of chromosomes. If such a gamete participates in fertilization, the resulting offspring may have conditions like Down syndrome, Turner syndrome, or Klinefelter syndrome, depending on the specific chromosomes involved. This can result in developmental issues, physical abnormalities, and various health problems. Overall, nondisjunction can significantly affect the genetic makeup and viability of the offspring.
This syndrome is caused by a new mutation in one or two genes in 60% of the cases. These are not inherited. The other 20% are inherited if one parent carries the mutated gene. In the final 20% both parents have to carry a different gene for their offspring to have the syndrome. In this case neither parent show any signs or symptoms.
