PGT-SR Testing

For people with a chromosome structural rearrangement also called a translocation, PGT-SR (Preimplantation Genetic Testing for chromosomal structural rearrangements) can be performed to improve the chance of establishing a healthy pregnancy.

Chromosome rearrangements

The aim of PGT-SR

The aim is to achieve a pregnancy that is unaffected by a chromosome imbalance due to the inherited structural rearrangement/translocation.

Chromosome rearrangements can be inherited or can happen spontaneously (de novo). Many carriers of balanced chromosome rearrangements are healthy and are unaware of their carrier status until they try to have children. Carriers of balanced rearrangements are at risk of producing embryos with the incorrect amount of chromosomal material, these embryos usually do not lead to a successful pregnancy.

PGT-SR can help identify embryos with the correct amount of chromosomal material that are most likely to lead to a successful pregnancy and healthy live birth.

If a parent has an unusual chromosome rearrangement will it always be passed on?

Your next step

The first step is to contact the PGT team at Care with a copy of your chromosome result to perform the initial check that imbalances arising from the translocation can be detected at the embryo stage.

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 chromosome report (called a karyotype) to allow our team to provide a swift answer to your enquiry.
