Objective To describe a family on whom it was possible to perform a rapid prenatal diagnosis for chronic granulomatous disease (CGD) using a denaturing high‐performance liquid chromatography (DHPLC) system. Methods For a family whose first‐born, a boy, suffered from X‐linked chronic granulomatous disease, fetal DNA was obtained from an ongoing pregnancy by amniocentesis early in the second trimester. Denaturing high‐performance liquid chromatography and direct sequencing were used to attempt to detect the previously identified X‐linked chronic granulomatous disease mutation. Results Our studies predicted that the fetus in question was not likely to be affected by chronic granulomatous disease, which was demonstrated to be correct at birth. Conclusions Here, we introduce a molecular diagnostic tool (DHPLC) for an effective and exact prenatal diagnosis of normality for the second‐born child, as determined from amniocentesis during the second trimester.
