This section of the website is all about the genetics of retinoblastoma (Rb).  The information contained here is designed to be quite general.  If you want more detailed information which is tailored to you as an individual, ask your GP to refer you to a local geneticist or one of the two geneticists who work as part of the retinoblastoma teams in the UK.

They can be contacted through the retinoblastoma treatment centres, websites below.

The information about genetics on our website was written by Megan Pritchard and reviewed by Dr Elisabeth Rosser and Dr Gerald Draper.


We are members of Genetic Alliance UK. If you would like to find out more about the work they do please visit their website:

The Genetic Alliance UK has some useful leaflets designed for people who are seeing or who will be seeing a geneticist. You can find these publications on their website.


The Retinoblastoma Genetics Screening Unit at Bart’s and the London NHS Trust has a website. This website has information about the type of testing they do. It also includes detailed information about genetics and a useful glossary of terms. This is a website that you, your GP, local genetic counsellor and ophthalmologist may find useful.
