title: Hemophilia and the female: considerations for the radiologist.
abstract: Hemophilia A and B are commonly considered male diseases because of their X-linked recessive inheritance, but clinical hemophilia is occasionally seen in females. This may represent an extreme example of the Lyon hypothesis in which a heterozygous female has only the one X chromosome bearing the aberrant gene in the active state.
