II B 2: Family History
Your pediatrician will also ask you questions about your family, and your spouse's: was any of your relatives in a wheelchair? Do you know why?
That may pinpoint the problem, because DMD can be inherited. Often, mothers carry the gene that causes DMD, so others with DMD may show up in the mother's family.
