If you are uncertain, contact us or visit the BSGM website to find your regional genetics centre. 

We accept referrals from outside our area on the basis of patient choice. This must be stated in writing by the referrer on NHS headed paper. However, as patients will often require follow-up, a referral to the appropriate regional genetics clinic is encouraged.

  • Why refer?

    Hereditary diseases are often rare and affected families require specialist advice and services. We offer urgent and routine consultations, as well as longer term follow-up. Our team work with a variety of medical specialties to provide joint clinics and seamless specialist services where possible.

  • Who to refer

    • Pregnant women who are affected, or who have a family history of an inherited condition.
    • Pregnant women seen before, who wish to review their screening and testing options. We liaise with the fetal medicine unit at St Thomas' and the relevant laboratories to minimise delays to patient care.
    • Children or adults with a genetic or chromosomal diagnosis.
    • Children with congenital anomalies and developmental delay; some tests may be arranged beforehand on discussion with the duty consultant or SpR.
    • Anyone with a genetic condition or family history who is seeking updated information, particularly before starting their family.
    • Individuals who have a personal or a strong family history of cancer, especially when the diagnosis is under age 50, bilateral, or includes rare combinations (breast/ovarian; colorectal/ovarian/uterine/GI).
  • When to refer

    • Consider referral to a regional genetics clinic at the time of diagnosis and at relevant times thereafter.
    • Refer as early as possible in pregnancy, preferably pre-conception.
    • Relatives may be referred to discuss future health and reproductive choices.
