Some gene therapy research trials have been performed in humans with mixed results. The future for gene therapy in hemophilia is continuing albeit at a moderate pace. There are many projects continuing in animal models.Improved long-term expression of the new genes will require the development of better vectors (the means of delivering the new genes into the cells).Call NHF's toll free number (1-800-42-HANDI) for more information about gene therapy for hemophilia.here are many projects continuing in animal models.

A first-trimester ultrasound exam is not standard because it is too early to see many of the fetusâs limbs and organs in detail. An ultrasound exam done this early is used to do the following: Estimate gestational age.
