• Duchenne muscular dystrophy;
  • Fetal sexing


Over a five-year period in the West Midlands there were 34 pregnancies to women who were possible carriers for Duchenne muscular dystrophy and who were known to the Department of Clinical Genetics. Fetal sexing was performed in only ten of 26 pregnancies to women of high or moderate risk, and of the five male fetuses discovered, only two were aborted. Overall, the 34 pregnancies resulted in one miscarriage, 14 males (of whom two were aborted and two were affected) and 19 females. Information was also obtained on five further possible carriers who were ascertained solely because they had an amniocentesis. These five pregnancies led to the birth of one affected male and to the termination of one male fetus.
