Abstract: | Family studies including the proband are usually needed before a prenatal diagnosis may be performed for Duchenne muscular dystrophy. We report here on prenatal diagnosis in a family where the solitary index case was dead, and where the consultand and her mother were assumed to be carriers by independent evidence. DNA analysis revealed that both the consultand and her mother had an X chromosome deleted for DNA material in the Xp21 region. The female fetus also carried the deleted X chromosome. |
