Being able to identify how a condition might have been inherited is a vital part of genetic diagnosis, and can provide families with important information about the chances of other family members also developing that condition, or of having another child with the condition (the recurrence risk). For many conditions, the type of inheritance may be identified by characteristic patterns seen in a family tree. For others, where more than one gene may be involved, or where genetics plays only a part in the development of a disease, the mode of inheritance may be much less clear. Sometimes, a definitive genetic diagnosis cannot be made and people have to be supported in coming to terms with this too.
