When a child is born with Down sysdrome when did the mutation occur?
Down syndrome is typically caused by an extra copy of chromosome 21, resulting from a process called nondisjunction, which occurs during cell division. This mutation can happen during the formation of the egg or sperm, or during the early stages of embryonic development. As a result, the genetic change that leads to Down syndrome occurs before or at the time of conception. Therefore, the mutation is present from the moment of fertilization.
When a child is born with a chromosomol mutation when did the mutation occur?
A chromosomal mutation can occur either during the formation of the egg or sperm, or after fertilization when the zygote is forming. This means the mutation could have occurred in the parent's gametes, or during cell division in the early stages of embryo development.

Will a baby be born with marfan syndrome if father has it?
There is a 50% chance that the baby will have Marfan. The father might pass on the gene that has the Marfan mutation, or he might pass on the gene that does not. Each child you have together has a 50% chance.
What age does down syndrome start to occur?
Down syndrome is something you are born with; it is not something that will suddenly "appear."
Are children of Down Syndrome parents normal?
That would mean that the mother is the one with Down syndrome, since men with Down syndrome are sterile. There is a 50% chance that the child will have Down syndrome and 50% chance that child will be born without.
How common is Marfan syndrome in the general population?
How Common Is Marfan Syndrome?According to the National Marfan Foundation - Marfan.org - 1 in every 5,000-7,000 babies born is a child with Marfan syndrome. Other statistics about Marfan syndrome75% of people with Marfan syndrome have an affected parent.Approximately 25% of all cases are due to de novo(spontaneous) genetic mutations. This means they are the first person in their family to be affected.Marfan syndrome is an autosomal dominant mutation; this means that, if the mutation is present, the person has the syndrome to at least a mild degree. It can not skip generations. A person with Marfan has a 50% chance of passing it on to their children.Estimates indicate that approximately 0.02% of the global population has Marfan syndrome.Marfan syndrome is found equally in all ethnicities.
Can a person with Down syndrome have normal kids?
That depends. Men with Down syndrome have been shown to be sterile, while women with Down syndrome are capable of carrying a child, with 50% likelihood that the child will be born with Down syndrome.
What are the causes of Noonan syndrome?
Noonan syndrome is usually caused by genetic mutations that affect proteins involved in signaling pathways that regulate cell growth and development. Most cases are sporadic, but some can be inherited in an autosomal dominant pattern. Mutations in genes such as PTPN11, SOS1, and RAF1 have been associated with Noonan syndrome.
