You may be considering PGT-M if:
PGT-M tests are created uniquely for each family. PGT-M can be performed for nearly any single gene disorder as long as the specific familial mutation has been identified and appropriate family members are available for test preparation where required.
It may be possible to develop a unique PGT-M test for you if you are the first person to be diagnosed with the condition in your family. All cases are assessed following referral.
PGT-M It is one of the best techniques available to assist in identifying and avoiding known certain diseases, allowing your baby to have a healthy start in life.
Pre-implantation genetic testing is for people concerned about passing a known inherited disease or condition, like cystic fibrosis, beta thalassaemia and Fanconi anaemia, hereditary breast and ovarian cancer onto their children. You won’t necessarily have fertility problems, though if needed we can help with these too.
Since PGT-M was first licensed by the Human Fertilisation and Embryology Authority (HFEA) the list of genetic conditions we can test for has been growing steadily. PGT-M can now be performed for almost any single gene disorder with an identified mutation and availability of appropriate family members. If you’re wondering whether you can have PGT-M for an illness affecting you or your partner,you can check the HFEA list of licensed conditions here. If your condition isn’t on this list, we’ll investigate whether we can develop a test for it and then ask the HFEA for approval.
PGT-M for single gene disorders involves testing embryos created through in vitro fertilization (IVF) and then transferring unaffected embryos. The following schematic shows how a section of DNA can be tracked from the parents through to the embryos to identify healthy embryos for transfer.
PGT-M uses linkage analysis to diagnose embryos. When PGT-M is performed for an autosomal recessive condition, unaffected and carrier embryos are used for transfer.
To reduce the risk of multiple pregnancies which is associated with IVF/PGT-M treatment, single embryo transfer is recommended. At CARE, the safety of our patients is key to everything we do and because the risk of complications is higher in a twin pregnancy, we recommend single embryo transfer following PG-M treatment. This has resulted in our multiple pregnancy rates being among the lowest in the UK, whilst maintaining among the highest success rates. If you have any additional, unaffected embryos from your treatment then they can be kept frozen for possible transfer in the future.
If you are eligible for NHS funded treatment – please contact your local genetics service and request a referral to CARE Fertility Nottingham.
If you are considering PGT privately funded treatment speak with your Insurance provider in the first instance as they may be able to provide more information about financial assistance. You can contact our PGT team using the self-referral form, providing copies of genetic reports to allow our team to provide a swift answer to your enquiry.
