Prenatally Diagnosed Hemophilia in a Newborn: a Case Report.

Hemophilia is the most common inherited coagulation disorder, and approximately one-half of patients are diagnosed as newborns. For prenatal diagnosis of hemophilia A, genetic tests are performed using chorionic villi (biopsy PCR chorionic villi sampling [CVS]) at 10 weeks' of gestation. The result in this fetus demonstrated an inversion within intron 1 in part for hemophilia A. This male infant, who was his parents' first offspring, was born after an uneventful pregnancy. An uncle suffered from hemophilia A. This report describes a newborn who was prenatally diagnosed with hemophilia A. The timely diagnosis of hemophilia in a newborn enabled the provision of adequate therapy, which led to a favorable outcome.
