Rare Disease Genetics Research

Below are some of our ongoing Rare Disease Genetics research studies. You can find out more about a particular study by clicking on the study title listed below. If you have any questions about the study, you can contact the research team using the details provided.

Research studies you may be eligible for if the underlying genetic cause for your disorder is known

Main aim:

To recruit a large group of patients with Di George syndrome and study them to see how frequently Di George syndrome causes Parkinson's disease. This will help us understand the cause of Parkinson's disease and perhaps suggest new treatments.

With any Whole Genome Sequencing (WGS) test ordered, a Record of Discussion (RoD) form will also need to be submitted. This document is to record the patient’s consent for genomic testing and their choice on taking part in research. Guidance on the patient choice conversation can be found here
 
This RoD form will be available for clinicians to download from this webpage. Once completed with the patient, it can be send to the lab with the corresponding test order form and sample.
Tests available to order will be listed in the National Genomic Test Directory. A test order form will soon be made available for clinicians on this webpage to download and complete. This form will include the address of the laboratory that the appropriate sample and completed form needs to be sent to.
 
Until the new Genomic Laboratory Service goes live, please continue to follow existing test order processes.
 
Later this year, the online test ordering tool for Whole Genome Sequencing will be integrated into the National Genomics Informatics System (NGIS) and clinicians will be able to search or filter to find a clinical indication, confirm eligibility criteria and start the test request process for their patient.
