The genes and chromosomes from each parent combine into new pairs which determine the traits a child inherits. Most often, genes produce normal traits. Sometimes, however, a gene becomes altered from its original form. Although researchers know that mutations occur, the reasons for their occurrence is not completely understood. Some mutations are not harmful, but most often a mutant gene functions improperly and causes a disorder, malfunction, or malformation within the body.
Mutations can occur in any generation.
If a spontaneous mutation occurs, it is then possible for a child to be the first family member to get Marfan syndrome, even though both parents are normal. Therefore, if one parent contributes the Marfan gene and one parent contributes a normal gene, the child will inherit the Marfan disorder. It is important to remember that parents have no control over which genes they pass on to their children, and, therefore, should not feel at fault if one of their children inherits a disorder such as the Marfan syndrome. Coping Living and coping with a chronic disability, regardless of its severity, is a challenge for most people. If you or your children have Marfan syndrome, know that there are many ways to adjust and to cope with its symptoms.
