Clinical genetics services

Clinical genetics services

Our clinical genetics service serves over five million people. Our team works together to offer accurate information and support.


Regional genetics clinics offer services to diagnose and assess the risk of you or your family inheriting a genetic condition. It is not always possible to make a specific diagnosis for a family or child, however, a genetic assessment will help you to understand the possible diagnoses and treatment options.


Genetic counseling


Because diagnosis and testing will often have an impact on the wider family, the genetic counseling process includes an explanation and risk assessment with any available options for family members.


It may take time to adjust to new diagnoses and to decide on the best possible course of action. Our team will provide up-to-date and unbiased information. We suggest asking for an update when the affected person and family members reach reproductive age, and before a new pregnancy. Testing, risk-reducing treatment and research options change over time.


Commitment to research


The genetics clinic is part of the Division of Medical and Molecular Genetics at King’s College London. Our team are committed to genetic research and academic excellence.


100,000 Genomes project


The South London Genomic Medicine Centre (GMC), hosted by Guy’s and St Thomas’, is one of the centres taking part in the 100,000 Genomes Project.


The national programme will focus on cancer and rare diseases and will enable pioneering research to decode 100,000 human genomes, a scale not seen anywhere else in the world.


Find out how Guy's and St Thomas' are involved in the 100,000 Genomes Project.



Prenatal genetics course

We are running a three-day, skills-based course from Wednesday 4 March to Friday 6 March 2020 exploring the application of genetics and genomics in a prenatal setting.


It is aimed at midwives and other health professionals working in prenatal testing but with little training in genetics tools.


Topics covered include:


  • obtaining a family history
  • identifying high-risk family histories
  • approaches to genetic testing
  • consent taking and counseling skills associated with providing information and results.


Genetic counseling experience


Due to the high volume of requests, we are unable to offer shadowing or work experience within the genetic counseling team.


For individuals interested in a career in genetic counseling, we offer a half-day of talks about various aspects of the profession and the day-to-day life of a genetic counselor at Guy’s clinical genetics.
