Our service: The Molecular Biology service offers a range of tests useful in the diagnosis, prognosis and treatment stratification for patients with a range of genomic mutations. Germ line mutations in heritable thrombophilia (factor V Leiden and factor II prothrombin) and hereditary haemochromatosis (HFE genotyping) are available for both diagnosis of new patients and in the context of predictive testing within affected families. Please note that a family history is useful if available. Our service also includes analysis of somatic mutations in genes important in haematological malignancies, such as myeloproliferative neoplasms, leukaemia and lymphoma and also in Neuropathology and Oncology where certain mutations are used to direct treatment decisions. Some tests are referred out to other centres, in discussion with the Principal Clinical Scientist.
Please note that samples and extracted DNA can be stored by the laboratory for potential molecular analysis and for clinical trials, contact the laboratory for details.
Samples: Any fluid or tissue containing nucleated cells may be analysed and must be provided in a sterile container. Blood or bone marrow must be provided anticoagulated with either EDTA or citrate. Bone marrow trephine FFPE must be decalcified with EDTA. Please send 1xblood tubes for routine testing of inherited mutations (in addition to any other request) and 2x blood tubes for malignancy testing. Samples for RNA-based analysis MUST be received by the laboratory within 72 hours as RNA is very fragile and liable to degrade quickly. The table below shows tests available and those that use RNA for analysis.
Any remainder sample may be stored for potential use in patient monitoring for residual disease and may also be used as controls in further tests. All storage is in accordance with HTA guidelines. Patients may refuse consent for use of their samples using the appropriate UHPNT documentation.
Advice: The appropriateness of samples and their sending can be discussed with the laboratory. For more clinical advice and interpretation of results, please contact the Principal Clinical Scientist.
