There is information on our On Diagnosis page about testing that can be done to predict whether an unborn baby is affected by PHTS or not. If you are thinking about having a baby, Pre-implantation Genetic Diagnosis (PGD) is an option available to prevent passing on PHTS to future children. Speak to your genetic specialist who will refer you to the correct hospital. PGD can be funded through the NHS, on successful application and specific criteria being met, or can be privately funded (approx. £10k).
IVF is the first part of the process to create the embryos for testing, PGD is the second part of the process which is the actual genetic testing.
More information on PGD can be found here:
We will be creating a PGD specific page at some point in the future.
