If you are concerned about your health, the health of a family member, or your family history, you should first speak to your family doctor or GP. They may be able to answer your question, or they may refer you on to our service or another service that can help. 

If you are referred to our service, you will receive an appointment at one of our clinics.

100,000 Genomes Project

Our service is taking part in the 100,000 Genomes Project - a national project which has been set up to help clinicians across the country to better understand and treat rare diseases and common cancers.

By studying thousands of genomes, our scientists and healthcare workers can improve their knowledge of diseases and work towards finding more effective treatments. They can start to predict how well a person will respond to a treatment (known as personalised medicine).

Did you know...

  • over 330,000 new cancers are diagnosed every year
  • at least 80% of rare diseases are genetic.

If you know have a rare disease or cancer and want to become a part of the 100,000 Genomes Project, please speak to your GP, who can refer you to our Clinical Genetics Department.

Genetics: cancer referrals

To make a referral relating to cancer, please:

  • write to us at North West Thames Regional Genetics Service, Level 8V, Northwick Park and St Mark’s Hospitals, Watford Road, Harrow, HA1 3UJ
  • email us
  • fax your referral on 0208 869 3106

For advice on a referral relating to cancer, please contact us:

BRCA1 and BRCA2 expedited testing

We offer expedited testing of BRCA1 and BRCA2 is available for patients who meet the testing criteria. Please email or fax us your referral using the BRCA urgent referral form to avoid delay.

Process for referrals

If your patient meets our cancer referral criteria, we will send them a family history questionnaire. Once we have reviewed the questionnaire, we will offer them an appointment or send them a letter containing appropriate screening advice.

Please let your patient know that it's important for us to confirm the family history, where possible, in order to determine eligibility. Unfortunately, this can cause delay especially if we don't have enough information at the beginning of the process.

If your patient has an identified genetic cancer susceptibility gene, we will accept a referral. We will need a copy of the genetic test report from the family member who has been tested.

If your patient's family does not have an identified genetic cancer susceptibility gene, then we usually only offer an appointment to someone who is affected. In some cases, where there is no affected relative available for testing, we would consider assessing an unaffected individual. The affected relatives must be blood relations, but can be through the maternal or the paternal side.
