How would I know if I carry a defective gene that could result in NDI if passed onto my children?

Examining your family history could reveal whether or not you carry an NDI causing gene. The most common form of inherited NDI is called X-linked NDI and is passed from mother to son. If that mother has a brother or a maternal uncle with NDI, then she can be sure that she is a carrier because her family history shows an X-linked inheritance pattern. However, there are many cases where a mother has a son with NDI, and there is no family history of this disorder. In this case the mother would need genetic screening to know whether or not she is a carrier. Doctors with extensive experience in screening for the NDI gene include Dr. Robert Wildin in the United States, Dr. Daniel Bichet in Canada, Dr. Nine Knoers in Nijmegen, The Netherlands.
